     This basin  status report is one of   27   scheduled for
 completion  in Region X of EPA for the calendar year 1975.  The
 information presented herein is based upon all of the documented
 data available to EPA at the time of the report distribution.

     Several of  these reports include a minimal amount of infor-
 mation which may not be enough to adequately evaluate the water
 quality status of the basin.  We feel that it is important to dis-
 tribute these reports regardless of the availability of data since
 the knowledge of a lack of data is also important to the decision
 makers.

     A report update is scheduled annually,  therefore, additional
 data made available in 1975 will be included in the next report.

     We welcome comments on this report as well as information con-
 cerning additional data and/or sources where additional data might
 be obtained.  Any correspondence can be addressed to Bill Schmidt,
 Chief, Water Quality Monitoring Section, 1200 Sixth Avenue,  Seattle,
Washington, 98101.  Telephone (206) (442-1193).

                          YAKIMA PROFILE SUMMARY
 A.   Ambient Profile Discussion:

      Long term analyses  using  the  "two-year running average" technique,—
 were completed from 1968 to  the  present  time for stream flow, nitrite +
 nitrate (NC^+NCU-N), ammonia (NH^-N),  total phosphorus (T-P), dissolved
 orthophosphate [Ortho-P), specific  conductance  (Cond), total coliforms
 (T-Coli), and  dissolved  oxygen (DO) at two stations on the Yakima River.
 The stations are located at  Kiona  (1), 30 miles above the mouth, and at
 Parker  (2), just below the Yakima metropolitan area at R.M. 104.6.  These
 analyses  indicated  the following:

      1.  Of the parameters studied, except for DO, most values were
          higher at  Kiona (1) than at Parker (2).

      2.  Although no major long  term trends in N02+N03-N levels are
          discernable, those  levels  at  Parker have approached, and
          those in the lower  river have greatly, exceeded the potential
          algal  bloom limiting  concentration of .30 mg/1.

      3.  Ammonia levels  have increased greatly at both stations, then
          leveled off in  1974.  This increase is approaching the.0.2
          mg/1  level  which is considered an indication of organic
          pollution.

      4.  T-P and Ortho-P levels  have generally shown a slight de-
          crease over the past  four years.  For both parameters, all
          levels at  both  stations were  above the potential  algal  bloom
          limiting concentrations of .05 mg/1 and .01 mg/1, respe'c-
          tively.  T-P concentrations appear to be inversely related
          to river flow based on  data at Kiona indicating point source
          effects, however the  same  relationship is not as  clear at
          the station at  Parker.
  V

      5.   Specific conductance  levels appear to be flow-related, par-
          ticularly  in the lower  river.

      6.   T-Coli  populations  have consistently exceeded State of Wash-
          ington water quality..standards at both locations.  Due to a
          lack  of point source  data, however, the sources of the bac-
          teria  are not known at  this time.

      7.   Daytime  DO  values were well above State standards at both
          stations.   It appears, however, that diurnal  DO fluctu-
          ations  produced  some  nighttime levels that violated State
          standards at a  few  locations.
          (See  Graph  18,  Cause-Effect section).

I/ Two year  running  average  technique  is explained in the  Ambient Profile
   section of this report.

-------
 B.  Source Profile Discussion;

     1.   Considering the total BOD and suspended  solids  loading  from known
         M&I sources in the basin, industrial  sources  contribute about  2/3
         of the BOD and 1/2 of the SS.  Major  contributors are Boise
         Cascade at Yakima and the Yakima  industrial treatment plant (BOD  &
         SS), U&I Sugar at Toppenish (BOD  & NH3-N), and  the Prosser  indus-
         trial treatment plant (BOD, SS, T-P & NH3-N).   All these discharge
         directly to the Yakima  River.  BOD and SS data  on the tributaries
         and drains are not available.

     2.   The principal municipal contributors  are the  treatment  plants  at
         Yakima (municipal), Ellensburg, and Richland  (directly  to the  river),
         and at Union Gap, Toppenish,  and  Sunnyside (via a major creek  or
         drain).

     3.   Data taken by the U.S.  Bureau of  Reclamation May - October  1974
         indicate that most of the basin's known  nutrient loadings,  during
         the irrigation season,  are provided by the tributaries  and  irrigation
         drains below Yakima.  Of  these, the loadings from the Main  (Marion)
         Drain, Toppenish Creek  and Sulphur Creek Wasteway are especially
         high.  Wide Hollow Creek,  although not a significant contributor
         of nitrates, is responsible for 1/4 of the basin's known ammonia,
         plus considerable T-P loading.  Because  data for most of Winter
         1973-1974 are not available,  the  trib./drain loadings cannot be
         determined for this period.  Individual point source loadings are
         shown on Tables 2, 3, & 4.

C.  Cause-Effect Discussion:

     1.   The water quality of the Yakima River is adversly influenced
         by sources between Selah (R.M. 118) and  the mouth.

     2.   Non-irrigation season concentrations  are generally greater
         than those during the irrigating  season, with the exception
         of pH, T-Coli and temperature.

     3.   Most nutrient concentrations exceed potential algal bloom
         levels from Yakima to^the mouth.  The detrimental effects
         of municipal and industrial  sources plus that of the trib-
         utaries and drains in the Yakima  area are reflected in  the
         graphs of these parameters.   Similarly,  the considerable
         nutrient input of the drains between  Toppenish  and Mabton
         is also very noticeable.

     4.   Municipal  and industrial  sources  and  Wide Hollow Creek  cause
         a  dramatic increase in  NF^-N  levels in the Yakima area.
         U&I  Sugar at Toppenish  plus  the other drains between Top-
         penish and Mabton contribute  to a further increase down-
         stream.

     5.   A  progressive increase  in  conductivity,  and to  a lesser ex-

-------
                                   -3-

         tent turbidity, is obvious from the upper reaches to the mouth.
         The increase in the irrigation season levels between Top-
         penish and Mabton is particularly obvious.

     6.  Most total coliform samplings violated the State water quality
         standards below Ellensburg during the period evaluated.   Due
         to a lack of point source data, it is not clear at this  time
         what is causing these high levels.

     7.  Graph 16 shows no DO violations since these samples were taken
         during daytime hours; however, diurnal  data taken earlier
         (Graph 18) shows violations of State water quality standards
         on the middle and lower reaches of the river.   The diurnal  DO-
         percent saturation level  variations, and the chlorophyll-A
         data on Graph 19 are indicative of algal  bloom  activity  at
         various locations from immediately upstream of  Roza Dam  to
         the mouth.

D.   Three tributaries to the mainstem Yakima are designated as separate
State water quality segments.  Available data for selected parameters
were graphed, over the same time period as the cause-effect graphs,  for
the downstream station on each tributary.   Winter 1973-74 data was not
available for the Wilson Creek and Naches  River stations.

     1.  Wilson Creek:
         Spring and summer. N02+N03-N levels approached,  and at one point
         exceeded, the potential  algal  bloom concentration.   Phosphorus
         concentrations exceeded the potential  algal  bloom levels
         throughout the 1974 irrigation season.   pH levels were'within
         the water quality limits  over the period for which data  was
         available.

     2.  Naches River:
         The water quality of the  Naches River,  as measured near  the
         mouth, appears to be quite good.   N02+N03-N concentrations  were
         well below the potential  algal  bloom level.  T-P levels  were
         generally below, and Ortho-P levels averaged at,  their re-
         spective potential  bloom  concentrations,  with the highest
         occuring in the spring.   Ammonia  levels were low, and pH values
         were well  within the limits of the State standard throughout
         the period.

     3.  Wide Hollow Creek:
         Nutrient levels in  Wide Hollow Creek greatly exceeded their
         respective potential  algal  bloom  levels,  especially during
         the winter.  Some winter/spring NHs-N concentrations ap-
         proached or exceeded that level  considered as being indic-
         ative of organic pollution.  Total  coliform levels were  well
         above the Washington water quality standard over the entire
         period studied;  pH values were rather high, reaching the upper
         limit of the State  standard in late July and early August.

                          YAKIMA KTVEK BASIN
                             INTRODUCTION
       "The Yakima Subregion,  an area covering '6,062  square  miles
 and representing about 2 percent of the total area of the Columbia-
 North-Pacific Region, lies totally within  the State  of Washington.
 About-45 square miles are water and 6,017  are land.

       The Cascade Range, rising on the western border of the
 Yakima Subregion to elevations  of six to eight thousand feet,
 is flanked for many miles on  the east by southeastward trending
 upwarped ridges.  The Wenatchee Mountains,  largest of the uplifts,
 comprise the northern border  of the subregion.  The  Yakima  River
 flows east and south through  the Kittitas Valley from its ruggedly
 glaciated headwaters area. South of the valley, the river  cuts
 through  the flanking Manastash  and Uratanum  Ridges  in a deep canyon.
 The river enters the middle valley above Yakima through a gap cut
 in Selah Ridge and leaves it  through Union  Gap in  Ahtanum Ridge.
 Cleman and Cowiche Mountains, TietonT"Selah/ Yakima,  and Ahtanum
 Ridges border the" middle valley.   Rattlesnake Hills  crossing eastern
 Yakima and northern Benton Counties  and Horse Heaven Hills  to the
 south are prominent features bordering the  lower valley in  its
 80-mile  reach from Union Gap  to the  Columbia River.   The Yakima
 River joins the Columbia River  at an elevation of  340 feet.  The-
valley bottoms, the adjoining terraces, and the surrounding gentle
 slopes contain the subregion's  agricultural land.

       The larger glacial lakes  fed  from the mountain headwater
 area have been improved  as storage reservoirs.  The  Yakima  River
 is  the outlet of Keechelus Lake,  the westernmost of  three such
 lakes.   Ten miles downstream the  Yakima River is joined by  the
 Kachess  River,  a larger  reservoir outlet; and 10 miles  farther
 down its  course the Yakima is joined by the Cle Elum River  flowing
 from Cle  Elura Lake, largest on  the Yakima syste.ni.  Teanaway River,
Swauk Creek,  and several  smaller  creeks contribute drainage from
the  Wenatchee Mountains.   Taneura, Manastash, and Umtanum Creeks
flow eastward between parallel  ridges to join 1;he Yakima from the
west.

       Joining  the  Yakima below its deep canyon section, the Naches
River  also  taps  a large  and productive.watershed east  of the Cascade
summit.  :0f its  tributaries, Bumping River, flowing  from the lake
of that name,  and Tieton  River, outlet of Rimrock  Lake  (Tieton Dam),
and-Clear Lake  reservoirs  are the most important.  Below Union Gap

-------
the major  tributaries of the Yakima are Ahtanum, Toppenish,  and
Satus Creeks  entering from the west.

       Geology of the subregion is relatively simple as the  entire
area is underlain by a great thickness of flows of dark gray to
black basaltic lava.  Fairly large exposures of rock may be  found
along the  larger stream valleys and at higher elevations on  the
hills.  A  few layers of sediments are interbedded in the lava.

       A period of deformation followed deposition of the lava', and
anticlinal ridges and closed basins developed in the lava.   Coarse,
heavy sediments accumulated in the depressions.  When a drainage
system again  developed and streams began to entrench thjeir channels,
the major  streams cut deep, steep-walled canyons through the ridges.
Much of the sediment was removed from the basins.  Gravel deposits
were left  in  many of the" valleys.

       During glacial time, the. main river system was dammed, and
the canyons and deeper basins were flooded.   Thick deposits of silty
to sandy sediments of glacial origin accumulated in the lake.  After
the dam broke and the streams were again free to cut their channels
to former  depths, much of the lake sediment was eroded.  Remnants
still remain  throughout the area.

       Since  the disappearance of the lake,  windblown materials" have
blanketed most -of the area.  Some of the material is of local origin,
while other material has been transported from-outside the-subregion.
Much of the soil, especially^ in the upland areas,—has developed from
the windblown mantle.  This has left predominant soils of medium
textured sandy loams and silty loams of considerable depth.   The
soils have developed under scant rainfall and have a high content of
the mineral elements of fertility.
                          Precipitation

       There is a sharp reduction in precipitation as the elevation
decreases in an easterly direction from the summit of the Cascade
Range.

       For example, within a distance of 20 miles, annual precipita-
tion decreases from 92 inches at Stampede Pass (elevation 3,958 feet)
to 22 inches at Cle Elura (elevation 1,920 feet).   Within the next
20 miles, it decreases to 9 inches at Ellensburg (ele"vafibn"~
1,727 feet).  Annual precipitation ranges from less than 10 inches
in th« lower valleys to 100 inches or more at the crest of the
mountains.  Approximately 50 percent of the precipitation falls in
the four months October through January, and 75 percent in the
period October through March.  Total Rainfall for the two driest
months, July.and August, is less than 5 percent of the annual.

fiMBIEIMT PROFILE

-------
                        PROFILE GRAPH EXPLANATION
     The two-year running average technique is a graphical  representation
of long term ambient data designed to smooth out irregularities in the
data.  The technique has no statistical significance; however, it does
show long term trends in the data.

     Data from 1968 to 1974 was first reduced to consecutive monthly
averages.  Then the monthly averages for two years, January 1968 to
December 1969, were averaged and the point plotted at December 1969
(using the flow graph as an example).  Next, the time plot  was advanced
3 months and the monthly averages for that corresponding two-year period
April 1968 to March 1970, were averaged and the point plotted at March
1970.  This process was continued at 3 month increments until  September
1974, and 20-21 points in all  were plotted per graph.  Total  coliform
points represent geometric means as dictated by convention.
