INTRODUCTION The ecology of York Haven Pond near the Three Mile Island Nuclear

~

Station (TMINS) has been under investigation since February 1974.

' Studies-initiated in April 1974 include analysis of ambient water

~

quality, ichthyoplankton (far-field), ichthyoplankton entrainment, macroinvertebrates, fish-population dynamics, impingement of fishes,

- creelisurveys, and-thermal plume mapping.-

This report discusses the progress of investigations conducted in January 1981.

2 COMPLIANCE WITH ENVIRONMENTAL TECHNICAL SPECIFICATIONS (ETS)

Objectives: To determine compliance with the nonradiological (aquatic) environmental monitoring pr.ograms specified in sections 3.1.1.a.'(4), 3.1.2.a., 4.2, and 4.6.1 of the ETS and to insure that said _ programs are performed as detailed in the Generation Procedures Manual.

Progress:

Ice cover on York Haven Pond throughout January pre-vented compliance with the following programs: macroinvertebrates, trapnet,-seine, electrofishing, and ambient water quality (Table 1).

Creel surveys were conducted only at the York Haven Generating Station area; all other areas were inaccessible due to ice cover.

The: impingement program was successfully completed at both Unit 1.and 2.(during all time periods) in January.

A program by program sumenry of the progress for January follows.

FMCROINVERTEBRATES Objective: To describe the diversity and distribution of the benthic.macroinvertebrates. occurring at the five benthos sampling

. stations near TMINS.

Progress: Ice cover prevented sampling throughout January (Table 1).

Progress on the 1980 annual report 1. '.uded the entering of all

. data on-the computer and the. completion of running tables, analysis of_ variance computations,.and a first draft of the methods section.

'ICHTHYOPLANRTON.

Objectives:

(1) To -determine the species composition, abundance,-

and distribution of ichthyoplankton in York Haven Pond; and (2) To Linvestigate ichthyoplankton entrained'at TMINS Unit.1 and 2 Intakes.

3 FAR-FIELD

-Progress:

Running tables were co=pleted and typed and most figures were finished.

The first draft of the results section of the 1980 annual report'was completed.

ENTRAINMENT Progress:- Work on all figures was completed.

Revisions were made to the ~section for the 1980 annual report and it was resubmitted to the-project director.-

TRAPNET -

0bjectives:

(1) To determine - the distribution and relative

' abundance of fishes in the Three Mile' Island area vulnerable to trapnet;. (2) To provide specimens for movements studies; (3) To

- monitor the occurrence of diseased fishes; (4) To provide specimens

, for radiation analysis; and ' (5) To determine reproductive status for fishes-throughout the year.

Progress:

Ic cover prevented sampling throughout' January (Table z

-1). ~ Most summary tables 'for the '1980 annual' report were finished as

' vere condition factors'for the pu=pkinseed, bluegill, and black

~

crappie.

' SEINE-Objectives:

(1) To determine the species composition of fish

upst'eam and~ downstream from the TMINS. Discharge vulnerable to seine; r

(2) To. determine the relative condition factor for important species; and (3) Tofdetermine the reproductive status for fishes throughout the year.

Progress:

Ice cover' prevented sampling.throughout-January (Table 1). 'All^ summary tables an'd condition factor tables for the spottail

~

4

4 shiner and spotfin shiner were completed.

The first drafts of the methods and results sections of the 1980 annual report were finished.

~

IMPINGEMENT OF FISH Objectives:

(1) To determine the numbers and species impinged on the river water intake screens; (2) To determine day-night differences in impingement frequency; and (3) To determine the extent of mortality of impinged fish.

Progress:

Impingement surveys were conducted on 6-7 and 21-22 January at the TMINS Unit 1 and 2 Intakes (Table 1).

Unit 1 impinged 17 fish of'5 species weighing 37.2 g.

Most fish were young and all but seven were dead (Tables 2 through 5).. Fish biomass and numbers were highest during. the 6-7 January survey. More fish were collected at 1200 h than during the other survey periods.

The estimated impinge-ment for Unit-1 for January was 264 fish weighing 576.6 g (1.3 lb).

Unit 2 impinged 6 fish of 5 species weighing 17.3 g (Tables 6 through 9).

Most fish were juvenile and all but one were dead.

Fis'h numbers were identical for both surveys; however, biomass was highest

~

.during the 21-22 January survey. The esti=ated impingement for Jan-uary from Unit 2 was 93 fish weighing 268.2 g (0.6 lb).

The= total esticated-impingement at TMINS during January was 357 fish weighing 844.8 g '(1.9 lb).

Work was: initiated on the section for the 1980 annual report.

Statistical analyses which were performed included Kendall's tau correlations, t-tests, an'd nonparametric binomial tests. First drafts of the introduction and methods sections were finished.

5 ELECTROFISHING Objectives:

(1) To provide specimens for radiation analysis and movements' studies; and (2) To determine the relative abundance of fishes vulnerab'le to electrofishing in various parts of York Haven Pond.

Progress:

Ice cover prevented sampling throughout January (Table 1).

Rough tables for the 1980 annual report were completed and fish length and weight data were entered on the computer.

MOVEMENTS OF FISHES

.0bjective: To determine if fishes in waters receiving the TMINS effluent mix with fishes from other areas.

y Progress:

No fisherman recaptures were reported in January.

Rough tables and all statistical analyses for the 1980 annual report were completed.

CREEL SURVEYS Objectives:

(1) To' determine the extent and success of sport 4

fishing; and (2) To determine information on angler residence and use of catch.

Progress:

Surveys were conducted on 5, 10, 18, and 30 January e

(Table 1).only at the York Haven Generating Station; ice conditions prevented surveys in the General Reservoir, West Dam, and East Dam areas.

No anglers were interviewed in January (Table 10).

Suc=ary tables and the first draft of the methods section for

.the 1980 annual report were completed.

MBIENT WATER QUALITY Objective:

To determine concentrations of selected water quality para =eterscin ambient river areas and the TMINS effluent.

Progress: - Ice cover prevented sampling throughout January-(Table

1).. Work;was' initiated on the section for the 1980 annual report.-
