1.3 CENERAL AQUATIC SURVEILLANCE Objective:

discharges.

Surveillance programs shall be conducted to detect and quantify Oconee's effects on water quality, fish, periphycon, plankton, and benthos.

1.3.1 WATER QUALITY Specification:
A.
Synoptic water quality surveys at nine (9) sampling stations on Lake Keowee, four (4) stations on Lake Hartwell, and a station on the Keowee River between the lakes shall be conducted. Sampling locations are shown on Fig. 1.3-1 and Fig. 1.3-2, and required sampling parameters are listed in Table 1.0-1.
Temperature and dissolved oxygen measurements shall be made at 0.3, 1.5, 5.0, 6.5, 8.0, 10.0 meters and there-af ter every 2.5 meters to one meter off the bottom for lake samples.
BOD measurements on Lake Keowee shall.be taken at 0.3 meters, 3.0 meters and bottom depths.
BOD measurements on Lake Hartwell shall be made on samples 19 14 6 which are a composite of water from 0.3 meters, mid-depth and bottom depths.
All other specified parameters shall be measured at a minimum of three depths for each lake sampling station. At sampling station 605 (Figure 1.3-2), the Keowee River shall be sampled from 0.3 meters.
Dissolved oxygen will also be measured weekly from May through November at three locations:
(1) the Oconee discharge, (2) the lake surface (0.3 meter depth) the Keowee intake structure, and (3) the Keowee tailrace during hydroelectric plant operation.
Water temperature recording stations shall be established B.
at stations 502, 503, and 504. Temperature shall be monitored in a multi-point vertical profile, accurate to 0.5 C. Sensors shall be placed at a depth of 0.3 meters below the surface, on the bottom, and at -a minimum of six (6) intervals to describe the temperature profile.
A fourth temperature recording station shall be established to monitor the waters discharged from Lake Keowee through the Keowee Hydro Plant.
Bases:
Water quality measurements will be used to:- (1) establish base line data, (2) determine effects from Oconee Nuclear Station on the water quality and, (3) provide supporting data for the benthos, plankton, periphyton, and fish sampling programs.

1.3.5 BENTH0S Specification 3
The benthic macroinvertebrate populations of Lakes Keowee and Hartwell shall be sampled four (4) times p'er year.
Sampling stations shall be lecated on the lake side of the skimmer wall (502), in the vicinity of the dis harge (discharge canal and 504), at control stations on Lake Keowee (501 a i 506), 19 14 6 and.in Lake Hartwell below Keowee Dam (604 and 606).
Quanitative samples shall be taken with a modified Peta-aan grab.
Qualitative samples (e.g.,
sweep netting) shall be'done along the shore nearest each of the stations listed above.
Benthic organisms collected shall be identified to the genus level where practicable.
Diversity indices shall be calculated as well as data on the standing crop of benthic organisms, such as number per square meter and/or grams per square meter.
Bases Benthic organisms are valuable as indicators of water quality near the bottom of a lake or river.
Their relative immobility and several-month life spans are qualities which help make them " continuous monitors" whose survival may be limited by extreme conditions even when average c~onditions are favorable.
They cannot avoid adverse conditions and are slow to re-
~
populate an area, so that detrimental effects are not easily erased.
Benthic organisms may also be an important source of food.for fish.
Inasmuch as the distribution and abundance of benthic organisms are greatly i
dependent upon the bottom type available to them, the bottom type at each sampling station will be classified and reported.
The benthic samples taken by the techniques proposed above should be representative of both deep and shallow areas of Lake Keowee and of the several habitats presented by the Keowee River below the dam.

1.6 PLUME MAPPING FOR TEMPERATURE AND DISSOLVED OXYGEN Obj ective:
To previde temperature and dissolved oxygen data for defining the discharge plume and for checking the accuracy of predictions of plume characteristics.
Specification:
At least four times per year, special sampling studies shall l1914@
be made to identify and characterize the cooling water discharge plume with respect to dissolved oxygen and temperature. Data shall be collected from a minimum of 30 sampling points, follow-ing a sampling pattern designed to achieve coverage of the plume.
Three of the surveys shall be conducted during periods when the following conditions are expected:
- 1) Maximum condenser cooling water discharge temperature 2)
M'ximum acreage of discharge plume a
- 3) Minimum condenser cooling water dissolved oxygen concen-tration.
Bases:
The mapping program will define the temperature and dissolved oxygen gradients in the plume, especially in the region near the discharge where momentum and mixing are the prevalent processes influencing the plume's horizontal and vertical
- dimensions.
This mapping program will effectively complement the surveillance program defined in Section 1.3.
