                                INTRODUCTION
     As part of the National Acid Precipitation Assessment Program, the
U.S. Environmental Protection Agency initiated the National Surface Water
Survey (NSWS) in 1983.  The NSWS, which includes both lakes and streams, has
three primary goals and three distinct phases:  (1) quantify the present
chemical status of surface waters in the U.S. (Phase I), (2) assess the
temporal and spatial variability in aquatic chemistry and define the key
biological resources associated with surface waters (Phase II) and
(3) identify temporal trends in surface water chemistry and biology
(Phase III).
     The ELS-I was designed to provide the information needed to assess the
chemical status of lakes in areas of the eastern U.S. containing the
majority of low alkalinity systems.  Lakes were selected statistically from
the population of lakes within the northeastern, southeastern and upper
midwestern regions of the U.S.  Variables thought to Influence or be
influenced by surface water acidification were measured using standardized
methods.  The ELS-I data base may be used to Investigate correlative
relationships among chemical variables on a regional basis and to estimate
the chemical status of lakes within a specific region.
     The primary objectives of the ELS-I were to:

     (1)  determine the percentage (by number and area) and location of
          lakes that are acidic in potentially sensitive regions of the
          eastern U.S.;
     (2)  determine the percentage (by number and area) and location of
          lakes that have low acid neutralizing capacity in potentially
          sensitive regions of the eastern U.S.; and
     (3)  determine the chemical characteristics of lake populations in
          potentially sensitive regions of the eastern U.S. and provide the
          data base for selecting lakes for future studies.

-------
     Sampling for the ELS-I was completed in the fall of 1984.  The purpose
of this report, entitled Chemical Characteristics of Lakes in the Eastern
United States, is to present the results obtained during that survey.  The
report consists of three volumes, Volume I:  Population Descriptions and
Physico-chemical Relationships: Volume II:   Lakes Sampled and Descriptive
Statistics for Physical and Chemical Variables: and Volume III:  Data
Compendium of Site Characteristics and Chemical Variables.  This volume,
Volume II, provides supplemental information that was not presented in
detail in Volume I.  The additional information includes data for those
lakes that were part of the probability sample ("regular" lakes; Volume I,
Section 2.2.3) and those lakes that were not ("special interest" lakes;
Volume I, Section 2.2.5).
     This volume of the report is presented as nine sections including this
Introduction (Section 1).  Descriptions and definitions of parameters
presented here are given in Section 2.  Section 3 provides a map of the
eastern United States showing the three regions in which sampling was
conducted (Northeast, Upper Midwest and Southeast).  Three maps of these
regions, on which the eleven subregional boundaries are delineated, are
included.  Additionally, maps showing the locations of sampled lakes within
each state are presented.  Regular lakes, sorted by lake identification code
(Lake ID) and by lake names within states,  are listed in Sections 4 and 5,
respectively.  Similar lists for special interest lakes are given in
Sections 6 and 7.  Section 8 lists the U.S. Geological Survey maps used in
the selection of probability sample lakes (Volume I, Section 2.2).  The
final section (Section 9) includes estimates of selected physical and
chemical variables, based on the probability sample lakes, for the
subpopulation of lakes <2000 ha.  These estimates are presented as plots of
cumulative frequency [F(x)] and areal [G(x)] distributions (Volume I,
Section 4.3).  The distributions include those for physical variables
(Volume I, Section 4.4), primary variables  (Volume I, Section 4.7), and
secondary variables (Volume I, Section 4.8).  The reference values and
population estimates pertaining to these values are provided for the six

-------
primary variables, ANC, pH, sulfate, calcium, extractable aluminum, and
dissolved organic carbon (Volume I, Sections 4.5 and 4.6).  No reference
values for the physical variables or the secondary variables are given.
     The data presented here are a subset of the ELS-I data base.
Information concerning the distribution of the complete data set is
presented in the Notice (page ii).  The correct use and interpretation of
these data require an understanding the ELS-I design described in detail in
Volume I, Section 4.1.2.1.  Explanation of the cumulative distributions is
given in Volume I, Section 4.3 and in this volume, in Section 9.

                    DESCRIPTION/DEFINITION OF PARAMETERS
     To satisfy the objectives of the ELS-I, a number of physical and
chemical parameters were measured using standardized protocols (Volume I,
Sections 2.4 through 2.7).  The physical parameters such as lake and
watershed areas (Volume I, Section 2.4) were measured because of their
importance in interpreting chemical data collected from lakes.  The chemical
parameters measured (Volume I, Section 2.5) included those that are
considered to be relevant to evaluating the potential response of lakes to
acidic deposition and those that are most useful  in characterizing the
chemical status of a population of lakes.  The ELS-I data base contains the
values of each of these parameters, as well as extensive information on the
location and identification of the lakes sampled.
     Table 2-1 lists, in alphabetical order, the  names and units of the
parameters presented in this volume.  Additionally, the name of each
parameter as it appears in the data base is given.  Brief definitions and/or
descriptions of the methods used in their determination are given for the
parameters.  More extensive descriptions are given in Volume I, Section 2
and in Hi 11 man et al. (1986).

Acid neutralizing capacity is a measure
of the amount of acid necessary to
neutralize the bicarbonate, carbonate,
hydroxyl, and other bases in a sample.
Acid neutralizing capacity was measured
in the analytical laboratory in an
unfiltered, unacidified aliquot, using
acidimetric titration and modified Gran
analysis (Hillman et al. 1986;
Kramer 1984).

Extractable aluminum is an estimate of
labile, monomeric aluminum.  Aluminum
in an unacidified, filtered sample was
complexed with 8-hydroxyquinoline and
extracted with methyl-isobutyl ketone
(MIBK) in the field laboratory.  The
aluminum was then measured in the
analytical laboratory, using the method
described in Hillman et al. (1986).
Values were converted from mg L'1 to
ug L'1 for data analysis.

Total aluminum was measured in the
analytical laboratory in an unfiltered,
acidified (HN03) aliquot (EPA 202.2,
AAS, atomic absorption spectroscopy,
graphite furnace).  Values were
converted from mg L'l to ug L'1 for
data analysis.

Ammonium ion was measured in the
analytical laboratory in a filtered,
acidified (H2S04) aliquot (EPA 350.1,
colorimetric, automated).  Values
were converted from mg L'1 to ueq  L-1
for data analysis.

mg L-1 to ueq L'1 for data analysis.

Chloride ion was measured in the
analytical laboratory in an aliquot
from a filtered, unacidified sample
(ASTM 1984; O'Dell et al. 1984, ion
chromatographic methods).  Values were
converted from mg L"1 to ueq L'1 for
data analysis.

True color is a measure  of the dissolved
and colloidal substances  in water that
reduce light transmission.  True color
was measured in the  field laboratory  in
a centrifuged aliquot  (to remove
particles), using a  Hach model CO-1
Comparator (EPA  110.2, modified).

Conductance is a measure  of the
resistance of a water  sample to an
electrical current.  Conductance was
measured  in the  analytical laboratory
using  a conductivity cell  (EPA 120.1).

Date  sampled is  the  date on which the
lake  sample was  collected.

Sampling-site depth  was  measured using
a weighted line,  and was not necessarily
the maximum lake  depth.

Dissolved inorganic carbon was measured
in the field laboratory.  The sample was
drawn directly into a syringe from the
Van Dorn water sampler at the lake site,
filtered, and analyzed, without exposure
to the atmosphere, using a Dohrmann
model DC-80 carbon analyzer with an
infrared spectrophotometric detector
(EPA 415.2, modified).

Dissolved organic carbon was measured in
the analytical laboratory in a filtered,
acidified (H2S04) aliquot (EPA 415.2,
infrared spectrophotometric detector).

Elevation of the lake surface was
determined from USGS topographic maps
or was estimated from topographic
contour lines.

the analytical laboratory in a filtered,
unacidified aliquot, using an ion-
selective electrode (ISE, EPA 340.2,
modified).  Values were converted from
mg L-l to ueq L-l for data analysis.

Dissolved iron was measured in the
analytical laboratory,  in a filtered,
acidified (HN03) aliquot (EPA 236.1,

Lake ID is a seven-character, unique
identification code assigned to each
lake.  The first character is a digit
representing the Region (1, 2, or 3);
the second is a letter indicating the
subregion; the third is a digit, giving
the alkalinity map class; and the
fourth, a dash.  The last three digits
are the assigned lake number.

Lake name was taken from the USGS
topographic maps or, in some cases,
substituted with more recent information
from state sources.  When a number of
small water bodies were identified by
only one name on the map, a qualifier
was  added to the name, such as
"southern," to  identify the lake
sampled.  When  no name was listed,
"(NO NAME)" was entered into the data
base as the lake name.

Latitude was read from the USGS
topographic maps in DD-MM-SS  (degrees-
minutes-seconds) format.

Longitude was  read  from the  USGS
topographic maps in DDD-MM-SS  format.

Dissolved magnesium was measured in  the
analytical  laboratory  in  a filtered,
acidified  (HN03) aliquot  (EPA  242.1,
AAS, flame  or  furnace).   Values were
converted  from mg L'1  to  ueq  L"1 for
data analysis.

Dissolved manganese was measured in  the
analytical  laboratory  in  a filtered,
acidified  (HN03) aliquot  (EPA  243.1,
AAS, flame).   Values were converted
from mg  L"1  to ug L'1  for data
analysis.

Nitrate  ion was measured  in the
analytical laboratory  in  a filtered,
unacidified aliquot, using ion
chromatography (ASTM 1984; O'Dell et al.
1984).   Samples taken  before November 2,
1984, were analyzed in a  slightly
different manner  (see  Volume I,
Section  3.5.2).   Values were converted
from mg  !_•1 to ueq L- 1 for data
analysis.

Closed system pH  was measured in the
field laboratory, using an Orion
model 611 meter and an Orion Ross
combination pH electrode  in a syringe
sample unexposed  to the atmosphere
(EPA 150.1).

Total phosphorous was measured in the
analytical laboratory  in  an unfiltered,
acidified (H2S04) aliquot, using either
of two automated, colorimetric,
phosphomolybdate  methods:  for normal
phosphorus levels, using  a 15-mm
absorption cell,  or for low levels, a
preliminary method using  a 50-mm
absorption cell (USGS  1-4600-78).
Values were converted  from mg L'1 to
ug I/1 for data analysis.

Dissolved potassium was measured in the
analytical laboratory  in  a filtered,
acidified (HN03)  aliquot  (EPA 258.1,
AAS, flame).  Values were converted
from mg  L- l to ueq !_•l  for data
analysis.

Secchi disk transparency was determined
by averaging the depths of Secchi disk
disappearance and reappearance.  When
the Secchi disk was visible on the lake
bottom,  that value was  entered.

                                  SECTION 3

                         NAPS SHOWING LAKE LOCATIONS
     This section provides maps showing the study area and location of all
lakes (both probability sample or regular lakes, and special Interest lakes)
sampled during the ELS-I.  Figure 3-1 shows the regions and subregions that
defined the areas of interest for the ELS-I.  Figures 3-2 to 3-4 show these
three regions of interest, their subregions (as indicated by letter
designation), and the three alkalinity map classes.  These three factors
(region, subregion, and alkalinity map class) served as the stratification
factors for the statistical design of the Survey (Volume I, Section 2.2.1).
     The alkalinity map classes shown in Figures 3-2 to 3-4 are based on
maps by Omernik and Kinney (1985), Omernik and Griffith (1985) and
Omernik  (1985).  These areas represent map units that contain lakes, the
majority of which were anticipated to exhibit alkalinity values within
expected ranges.  These map classes are not based on ELS-I measured lake
ANC values.
     Figures 3-5 to 3-22 show maps of each state with subregion boundaries,
as appropriate, and locations of the sampled lakes.  The subregion
boundaries shown here may differ slightly from the original base maps used
to delineate subregions.  Lakes selected as part of the probability sample
(regular lakes) are distinguished from special interest lakes by open
squares and "+" symbols, respectively.  Maritime states such as Maine and
Massachusetts show offshore lakes that were located on islands not
represented on these maps.  The map of Michigan (Figure 3-10) does not show
two lakes that were sampled on Isle Royale located in Lake Superior.

                                  SECTION 4

                       REGULAR LAKES SORTED BY LAKE ID
     This section (Table 4-1) lists all regular lakes (those that were part
of the probability sample), sorted by Lake ID.  Each Lake ID,is a unique
seven-character code.  The first character Identifies the region In which
the lake is located (1, 2, or 3); the second character,  the subregion (A
through E); the third character, the alkalinity map class (1, 2, or 3);  the
fourth character, a dash; and the last three, the assigned lake number.   A
lake with the ID of 1A1-010 1s located 1n region 1 (the  Northeast),
subregion A (the Adlrondacks), was selected from alkalinity map class 1
(<100 ueq L" ), and is the tenth lake numbered 1n this group.  Some lakes
were dropped 1n the selection process or were not sampled (Volume I,
Section 2.2.4); therefore, the assigned lake numbers are not consecutive.
For a description of the lake selection process, see Volume I,  Section 2.2.
     The additional Information provided in Table 4-1 includes  lake name as
it appears on the USGS map; the name of the state in which the  lake is
located (given as the two-character postal code); latitude and  longitude (in
degrees-minutes-seconds); and the large scale USGS topographic  map, the  size
of the map (referred to in the tables as scale) and map  name.  The scale and
map name refer to those maps actually used to locate and characterize the
selected lakes.

                                  SECTION 6

                  SPECIAL INTEREST LAKES SORTED BY LAKE ID
     This section (Table 6-1) lists all  special  Interest lakes (those not
part of the probability sample) sorted by Lake ID.   Each Lake ID is a unique
seven-character code.  The first character Identifies the region in which
the lake is located (1, 2, or 3); the second character,  the subregion (A
through E); the third character, the alkalinity map class (1, 2, or 3);  the
fourth character, a dash; and the last three; the assigned lake number.   A
lake with the ID of 1A1-010 is located 1n region 1  (the Northeast),
subregion A (the Adirondacks), was selected from alkalinity map class 1
(<100 ueq L"1), and is the tenth lake numbered 1n this group.  Some lakes
were not sampled; therefore, the assigned lake numbers are not consecutive.
For a description of how the special Interest lakes were chosen, see
Volume I, Section 2.2.5.
     The additional information provided 1n Table 6-1 Includes lake name as
it appears on the USGS map; the name of the state in which the lake is
located  (given as the two-character postal code); latitude and longitude (in
degrees-minutes-seconds); and the large scale USGS topographic map, the size
of the .map (referred to on the table as scale) and the map name.  The scale
and map  name refer to those maps actually used to locate and characterize
the selected lakes.

            SPECIAL INTEREST LAKES SORTED BY STATE AND LAKE NAME
     This section (Table 7-1) lists all  special  interest lakes  (those  not
part of the probability sample),  sorted  by state and lake name.
     The table includes:  the name of the state  in which the lake is
located, the lake name as it appears on  the appropriate USGS map,  the  lake
ID as described in Section 5, the latitude and longitude (in
degrees-minutes-seconds) and the  date the lake was sampled.

                                  SECTION 8

                            US6S TOPOGRAPHIC NAPS
     Two types of USGS maps were used In the Survey, small-scale and
large-scale.  The small-scale .maps (1:250,000) were used 1n the initial lake
selection process and the large-scale maps (1:24,000, 1:25,000, and
1:62,500) were used for characterization of lakes and watersheds, refinement
of the lake selection process (Volume I, Section 2.2), and location of lakes
for sampling.

8.1  SMALL-SCALE NAPS

     Table 8-1 1s a 11st of all small-scale (1:250,000) USGS topographic
maps used In the ELS-I for Initial lake selection sorted by map name.  Parts
of states covered by the maps are Indicated In the middle column.
Publication dates provide unique map Identification; multiple publication
dates Include dates of map revisions.

8.2  LARGE-SCALE NAPS

     Table 8-2 1s a list of all large-scale (1:24,000, 1:25,000 and
1:62,500) USGS topographic maps used In the ELS-I for lake selection, sorted
by map name.  Publication dates provide unique map Identification;  multiple
publication dates Indicate dates of map revisions.

                                  SECTION 9

      POPULATION ESTIMATES FOR SELECTED PHYSICAL AND CHEMICAL VARIABLES
     The primary data outputs from the ELS-I data base are cumulative
distributions for total lake number and total lake area in any population or
subpopulation of lakes explicitly defined by the investigator.  The
distributions presented here were generated from sample data using the
procedures described below (Sectlc., 9.1) for the subpopulation of lakes
<2000 ha within the target population.
     The variables described in this section are those listed in Section 2
(Table 2-1).  The statistics and distributions describing the subpopulations
of lakes are given in Section 9.2.  Cumulative frequency distributions are
presented as F(x) or l-F(x), and area! distributions as G(x) or l-G(x),
depending on whether low or high concentrations (or values), respectively,
are of primary interest (Figures 9-1 through 9-179).

9.1  APPLICATIONS OF THE DESIGN

9.1.1  Defining the Target Population
     The identity of the map population, subsequently refined by the
exclusion of non-target lakes (Volume I, Section 2.2.4), defines the target
population.  The number of lakes comprising the target population is not
known, but rather estimated, because non-target lakes were identified only
in the probability sample.  In contrast, the map population, because of its
operational definition as all lakes appearing on 1:250,000-scale USGS maps
(Volume I, Section 2.2.2), is known precisely and serves as the point of
reference.  The map population is larger than the target population by
virtue of the exclusion criteria set forth for non-target lakes.  The sample
frame is the structure imposed on the map population by stratification and
generation of the list.  The frame population and sample selection are
                                      187

-------
  stratum-specific,  as  is  the  estimation  process.   Sample  data must  be
  weighted  by  stratum-specific weights when extrapolating  from sample results
  to estimates of  population parameters.  The method of extrapolating to the
  population is given in Section 9.1.2 and its importance  is discussed in
  Volume  I, Section  4.1.2.1.
      In the broadest  sense,  the target  population is all those lakes
  appearing on 1:250, 000-scale USGS topographic maps that could be sampled to
 yield data to satisfy the objectives of the ELS- I.  However, the inherent
  flexibility of the design permits any subpopulation of lakes from this
 overall target population to be defined on the basis of any criteria
 established from the attributes or measured variables for any lake.  The
 definition of these still smaller populations can be determined to answer a
 particular question.   For example,  a subpopulation of interest  can be
 defined as that  set of lakes  characterized  by elevation  greater than 300  m.
 Or the  subpopulation might be defined  on the  basis of sulfate or dissolved
 organic carbon concentrations greater  than  or equal  to X.   Estimates of
 subpopulation characteristics can be made in  the  same manner as  for the
 entire  target population  by applying the proper weights.

 9-1>2   Estimating the  Target  Population  Size and Associated Variance
        from Sample  paja
     The number of  target  lakes (N)  within an alkalinity map class  stratum
 is estimated  by the equation:
                               *   A
                                 -Nn,
where:
       *
      N  = the number of lakes in the stratum map population, and
      Nn "   e estimated number of non- target lakes in the stratum
N  is known from the initial map population (Volume I,  Section 2.2.2)
     A                                                              ' '
     Nn must be calculated from the equation:
                         Nn - (N*/n*)  [n+ (n   /q)]f
                                      188

-------
where:
     n  - the total number of lakes in the probability sample selected
          from the map population within the alkalinity map class stratum
    nnb = t*ie num^er °f lakes selected in the probability sample determined
          to be non-target by the examination of large-scale maps

    n   = the number of lakes in the probability sample determined to be
          non-target during field sampling
             *
               - n«k - n« \
                              proportion of completion, i.e. the proportion
n  • nnb " no
where:
                 " nnh   /    °f lakes selected for visitation that were
                    nD        actually visited.
     n  - the number of lakes not visited, representing incompleteness
          in the field sampling.


     Some of the lakes scheduled for field visitation subsequently were not

visited by field crews (Volume I, Section 2.2.4).  The group of lakes that

were not visited contained an unknown number of lakes that would be

classified as non-target.  It was subsequently necessary to expand the

number of non-target lakes observed by the field crews (n  ) by q to yield
                                                         na
an estimate of the total  number of non-target lakes in the field sample

(including the number of non-target lakes expected within n ).

     Weighting, or expansion, factors are necessary to estimate the

population of lakes in the target population and are calculated as follows:

                             A  ***      it
                         W = N/n     -  N /n'

where:
      ***    *
     n    = n  " nnb " nna " no' the number °f lakes visited and
            characterized as target, i.e., the number of lakes from which

 Rearranging the equation yields

      The total  area of target lakes  (A)  is  estimated  similarly:
                               A    — ,
                               A -  W£A.,
 with  summation  over all  lakes in the  stratum  sample.
                   A     A
      Variances  of N and  A,  for single strata,  are estimated by:
      A  A       *   it                   -t
      V(H)  -  [N (N  -  n')/(n'  -  l)][n   /n'][(n'  - n    )/n'], and

      V(A)  -  [N*(N*  -

 For multiple  strata,  estimates  and variances are additive,
      N  - £ Nh, V(N)  -£v(Nh), A = E Ah, and Y(A) = £ 0(Ah).
 Standard errors (of estimates)  are the square roots of variances.  (To use
 the above  formulae, see Table 4-4, Volume I, Section 4.2.2, and calculate n'
 from  n' -  N*/VI.)
      In all analyses, the sample was treated as a simple random sample
 within  strata.  The ordering of the lakes and the systematic selection
 process increase  precision over a random sample.   Therefore, estimates of
 precision  are conservative.

 9.1.3  SubDODulations
      Estimations of subpopulation parameters require more structure than the
 basic population estimates and are generally of more scientific interest.
 For example,  each observed value of X defines a subpopulation of lakes
 having a value of X < that value (lakes < 300 m,  lakes < pH 6.5, etc.).
 Estimates and corresponding variances can be constructed for these
 subpopulations over any combination of strata if the identification of the
 subpopulation is explicit.
     For economy of computation, the algorithms used in generating all  the
statistics  for the Survey are quite different,  but  are mathematically
identical  and best understood by formulae generated  as a simple modification
                                      190

of the single stratum equations, given in Section 9.1.2:
                   ***                ^-»     x-^
     replace each n    by n  and each 2^ by  2-, •,
              ***
                  hv r

where:
          nz  = the number of sampled lakes in the subpopulation z and
        2 z  = the summation over the sample lakes in the subpopulation z.

     A useful generalization, appropriate for any subpopulation and any
combination of strata, is that

                         N = £w, and A = 2>A,

where summation is over the appropriate subset of sample lakes in the
appropriate strata, and where the weights (W) are assigned according to the
stratum in which the lake belongs in the map population.
     A further generalization used in the data analyses leads to similar
formulae for mean and variance of any variable, X, over any subpopulation
and combination of strata:
     Mean(X) =   WX/, an(J Var1ance(x) =

These are estimates of the parameters of the population of lakes defined by
the set of sample lakes in the summation, and characterized by the
distribution, F(X) (Section 9.2.2).
     The importance of the weighting factors cannot be overemphasized.   As
is shown by example in Volume I, Section 4.1.2, and stated several times in
this report (for example, Section 9.1.2), estimating population parameters,
or examining relationships among variables with the expectation that these
relationships are representative of the population, from sample data without
accounting for weights can lead to erroneous calculations and incorrect
interpretation.
                                      191

-------
 9.1.4  Restrictions
      The use and Interpretation of any data set are restricted by the
 design,  the quality of the data obtained  and the sampling  protocols.   The
 frame and target populations and the period of sampling  are  the primary
 considerations influencing the proper interpretation of  the  ELS-I data.
      The period of sampling restricts conclusions to the fall  of 1984.
 Until  Phases II and III are completed,  the  accuracy of extrapolating  the
 index sample to other times of the year or  to other years  will  not be known.
      Additional  restrictions result from  the sampling frame.   Most simply,
 no  conclusions can be drawn for lake populations  not included  in the
 original  frame.   Lakes less than 4 ha in  surface  area are  generally not
 shown  on 1:250,000-scale USGS maps used to  establish the frame  population.
 Consequently,  the ELS-I omitted lakes less  than 4 ha because lakes of this
 size  are generally not represented at this  map  scale.  However,  small lakes
 may represent  an  important  resource that  could  not  be sampled  practically or
 statistically  in  this  study.   Therefore,  no  direct  conclusions  can  be drawn
 about  this  population  of lakes.
     As  was  noted 1n  Section  9.1.3,  it  is essential  to the accurate
 interpretation  of the  data  to identify  clearly  any  population for  which
 inferences  are made.   However,  there  is considerable flexibility  in defining
 a population to be  described  if it  is a subset of the original  target
 population.

 9.2  DESCRIPTIVE  STATISTICS AND  CUMULATIVE DISTRIBUTIONS

     The primary  objectives of the  ELS-I were to  characterize the chemistry
 of  lakes in potentially  sensitive regions of the U.S., to estimate the
 numbers of low ANC  and  low pH lakes, to identify where those lakes are and
 to describe their characteristics.  The Survey addresses these objectives by
 its stratified design permitting description of the populations of lakes in
 each of the 33 strata, representing the throe alkalinity map classes within
 each of the 11 chosen subreglons (Volume I,  Sections 2.1  to 2.3).  These
 strata represent the basic analytic units, but analyses  also may be
performed on any combinations of strata that have meaning to the
 investigator within regions, subregions, or  subpopulations.

                                      192

-------
9.2.1  Population Distributions
     Each population described 1s summarized on a single page of output for
each variable as the cumulative distributions, supplemented by descriptive
statistics.  Tables of summary statistics are generated from these outputs.
The differences among the strata of the design can be inspected by using a
combination of the distribution plots and tabular information provided on
these data outputs.
     Data presentations as cumulative distributions enhance the utility and
flexibility of the ELS-I data base.  Specifically, low pH or low ANC, for
example, are not unequivocally or universally defined.  Thus, several
reference values (Volume I, Sections 4.5 and 4.6) for each of the primary
variables were chosen, primarily to facilitate comparisons among strata,
subregions, regions, or subpopulations.  However, the strength of the
designed output, as well as of the Survey design, is that any reference
value can be evaluated, providing flexibility in interpretation of the
output.  As the understanding of acidification processes improves, these
values can be changed, ensuring the future utility of the ELS-I data base.
The considerations noted in Volume I, Section 4.1.2.2, however, are
important in selecting additional reference values.

9.2.2  Definitions of the Descriptive Statistics;  Interpretation of
       F(x) and G(x) Data Output
     Each population description (Figures 9-1 through 9-179) is identified
by the variable and by the subset of lakes constituting the population being
examined.  A subset may represent all lakes in the Survey unit, for example,
a single stratum (1A1), a subregion (1A), a region (1), or a subpopulation.
                                     A     A
     The basic population estimates, N and A, and their estimated standard
                                                     A
errors are presented in the headings of the output.  N is defined as the
                                                                       A
estimated total number of lakes in the population being described, and A is
the estimated sum of the total lake area, over all lakes in that population
(denoted only as N and A on the output).  The indicated sample size
(equivalent to n***, Volume I, Section 2.3.2) is the number of sampled lakes
in the target population.  Reference values (X j, X-, X 3) chosen for
comparative analyses complete the heading material.
                                      193

-------
      9.2.2.1  Distributions--Interpretation of the distribution F(x) is
 given in Section 4.3, Volume I.  This section describes the distribution
 l-F(x).  For any reference value for variable X, l-F(x) is interpreted as
 the estimated proportion of lakes having a value of X >x.  The distribution
 l-F(x) is calculated as the ratio of NX, the estimated number of lakes
 having a value of X >x, to N.  The upper 95 percent confidence bound on N ,
 also scaled by dividing by N, is shown as a dashed line on Figures 9-1
 through 9-179.  Although only a one-sided upper 95 percent confidence bound
 is shown, a two-sided 90 percent bound can be made by using the existing
 bound and one equidistant below the distribution curve. This procedure
 would also provide a lower 95 percent one-sided bound.
      The function l-G(x) is interpreted similarly,  as the  estimated
 proportion of lake area in the population having a value of X >x,  for any
 variable X.   This cumulative area!  curve and its confidence curve  are
 determined analogously to the l-F(x)  curve.
      An example of interpreting these distributions is  derived from
 Figure 9-1.   At the value of extractable Al  = 50 ug L"1 for clearwater lakes
 <2000 ha, F(50) = 0.05 (calculated  and shown in the figure as p   = 0.052);
 the upper bound is read from the dashed line as 0.06.   These values are
 multiplied by the estimated total number of  lakes  in  the population,  4584,
 to yield 229  (calculated and shown  in the figure as N     237)  as  the
 estimated number of lakes in the population  with an upper  confidence  bound
 for that number,  275 (shown in  the  figure as Ncul  = 326).   The  calculated
 values  and those derived from the figure differ due to  the imprecision  of
 obtaining the proportions (0.05 and 0.06)  from  the  curve.   Reading  values
 from the curves is  suitable only for  obtaining  rough  estimates, due to  the
 introduction  of potential  error.  Precise  computation requires  the  use  of
 the  data base and  the  appropriate algorithms.
      Similarly,  at  extractable  Al = 50  ug  L"1,  the  l-G(x)  curve yields  0.02
 (calculated and  shown  in  the  figure as gc] = 0.025) and  0.03, which
multiplied by total  lake  area in the population  (277,621 ha) yields
5,552 ha  (calculated and  shown  in the figure to be A   = 6,959 ha)   and
8,329 ha  (shown  in the figure to be Acul = 10,769 ha) for the estimate and
upper bound for the lake area above extractable Al = 50 ug  L"1.  Again,
deriving estimates from the distribution plots is discouraged.

                                      194

     9.2.2.2  ££a£Mi£$--Associated with  each  distribution  are  the
following descriptive statistics:


     t    Mean and standard deviation,  appropriately weighted to reflect the
          estimated distribution,  l-F(x) [or  F(x)].  There are no comparable
          statistics for l-G(x)  [or G(x)].

     t    MIN and MAX are the  minimum and  maximum values of  variable X
          observed 1n samples  for  the population or subpopulation beinq
          examined.                                                   y

     t    The median is  the estimated value of  variable X such that half the
          number of lakes,  or  half the  lake area, in the population are
          above (or below)  this  value.

     t    The quintlies  (Qlf Q., Q3,  Q4, Q5)  are the values  of X that
          partition the  distribution  into  5 equal parts (e.g., the 4th
          quintile 1s the 80th percentile; Q5 1s the maximum value).  These
          values are particularly  useful in comparing differences among
          subpopulations.                                             3

     •    For each of the designated  reference  values of variable X, denoted

          where   pc  -  the estimated proportion of lakes,

                 NC  -  the estimated number of lakes,

                Ncu  "  the upper con^ X  for < X ).
