DETROIT RESERVOIR
WATER QUALITY DATA REPORT
JUNE 1965~*PECEWBER 1965
I. Introduction
A cooperative water quality study between the Federal Water Pollution
Control Administration and the U. S, Army Corps of Engineers was initiated
in June 1964, The purveys, conducted on a monthly schedule, were aimed at
determining any significant changes in water quality attributed to the
effects of storage or the season3! variance of reservoir operations.
This report contain? a description of methods and procedures employed
and the raw data collected, Because field investigations are still
continuing, np attempt has been made to analyze data to date. A data
report for June 1964--May 1965 precedes this report.
II. Field Procedure
A. Stations
Present sampling stations (shown in Table 1) are pinpointed by
use of a depth indicator and established station identification markers.
Stations 1-7 are sampled from a boat and stations 8-10 are taken
from shore.
During late fall and winter, the reservoir drawdown prevents
access to boat launching facilities,, Only shore samples (stations 8-10)
are taken during this period.
B. Sampling
All sampling on the reservoir is done from a FWPCA boat.
-------
A-3
Once on station, a vertical temperature profile was obtained by
lowering a (450') bathythermograph to the bottom. The thertnocline
position together with conductivity readings recorded from a Whitney
conductivity - temperature probe determined the depths for collection
of chemical samples.
Water samples for chemical analysis were taken by a series of
three-liter Van Dorn bottles placed in tandem on a hydrographic wire.
Two-quart polyethylene bottles are filled with sample, then frozen on
dry ice until time of analysis at the Portland laboratory.
Dissolved oxygen samples were drawn off of the Van Dorn
samplers, then dosed and prepared for titration upon completion of the
day's sampling.
pH was determined in the field by using a Hellige Model 600-CA
color comparitpr, or later determined in the laboratory by the use of a
Beckman Model-G pH meter.
Light penetration as pejrcent of light remaining was obtained
by using a Whitney deck-sea cell, readings being recorded every two feet.
III. Laboratory Procedures
On the run conducted in July and all previous surveys, the chemical
analyses were performed in the field using a Hach Model DR-EL field
laboratory.
The following analytical methods were used at the Portland laboratory;
Orthp Phosphate--The Stannous chloride method as described in
"Standard Methods." I'
JL/ STANDARD METHODS FOR THE EXAMINATION OF WASTE WATER, llth Edition,
APHC, AWWA, WPCF, published by American Public Health Association.
-------
A-4
Total Phosphate--The method for total and polyphosphate as
described in "Standard Methods." Beginning with the 10-21 samples, a
new method was used in the detection of total phosphate. The method,
published by Menzel and Corwin (LIMNOLOGY AND OCEANOGRAPHY, Vol. 10,
No. 2, April 1965) has superior detection limits and is soon to be
accepted in all FWPCA laboratories as routine analytical procedure.
Nitrate--The phenoldisulfonic acid method as found in
"Standard Methods."
On all the above determinations, the photometric results were
obtained through the use of a Beckman Model-rDB spectrophotometer. The
readings were made with 1 cm optical cells.
IV. Data Presentation
The data is arranged by each survey with the first survey (6-17-65)
in front and proceeding through each survey tn sequence. The station
data (within each survey section) is arranged by station, starting
from the station nearest the dam (1,) and working upstream.
The data headings are explained as follows:
Station--Identified as to location, range, etc.
Date--Month, day, year station was occupied.
Time--The local time messenger was released on the most
significant cast.
Depth--Descent from surface (in feet) at which sample was
obtained.
Temperature--Temperature in °F recorded from bathythermograph
slide.
-------
A-5
Conductivity--Specific conductance in micromhos per centimeter.
pH--The logarithm of the reciprocal of the hydrogen ion concentration
in moles per liter.
D0--Concentration of dissolved oxygen milligrams per liter of
water.
DO/% Saturation,--Ratio of the amount of oxygen dissolved in the
sample, compared to the amount of oxygen necessary to saturate a sample of
the same water, as per calculations made by Whipple and Whipple.
