L'TRODUCTION The ecology of York Haven Pond near the Three Mile Island Nuc'. ear Station (TMDG) has been under investigation since February 1974.
Studies initiated in April 1974 include cualysis of a=bient water quality, ichthyoplanl: ton (far-field), ichthyoplankton entrain =ent, macroinvertebrates, fish population dynamics, impinge =ent of fishes, creel survey, and ther=al plu=e capping. The data coding program was initiated in January 1979.
This report discusses the progress of investigations conducted in February 1979.

MACROTNVERTEERATES Objective: To describe the diversity and distribution of the benthic macroinvertebrates occurring at the five benthos sa=pling s tations near TMINS.
Progress: Sa=pling was not atte=pted in Fel ruary due to ice and high river flows. Data are currently being analy_ed and tabulated for the 1978 report.
TRAPNET Objectives:
(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 radio-environmental studies; and (5) To determine 2 eproductive status for fishes throughout the year.
Progress: Sampling was not attempted in February due to ice and high river flows. Data are currently being analyzed and tabulated for the 1978 report.
SE INE Objectives:
(1) To determine the species composition of fish upstrcam and downstream from the TMINS Discharge vulnerable to seine; (2) To deternine the relative condition factor for important species; and (3) To determine the reproductive status for fishes throughout the year.
258 18L
3 Progress: Sa=pling was not attempted in February due to ice and high river flows. Data are currently being analyzed and tabulated for the 1978 report.
DfPINCEMENT OF FISH Objectives:
(1) To determine the numbers and species impinged on the river water intake screens; (2) To determine day-night differences in impingemant frequency; and (3) To determine the extent of mortality of L= pinged fish.
Progress:
Impinge =ent surveys were conducted at the TMINS Unit 1 Intake on 8-9 February and 28 February - 1 March (Table 1). No surveys were conducted at the Unit 2 Intake due to ice in the trash bin.
Six tesse11ated darter were taken during the 8-9 February survey; 5 were dead. The total was comprised of 1 young, 4 juvenile, and 1 adult. Biomass was 4.3 g ( <' 0.1 lbs Tables 2 and 3.
The 28 February -
1 March survey yielded 51 fish of 7 species weighing 417.4 g (0.9 lb).
The group consisted of 12 young, 19 juvenile, and 20 adult; 29 specicens were alive and 22 dead (Tables 4 and 5).
The total estbnated impingement for TMINS in February was 798 fish weighing 5,903.8 g (13.0 lb).
ELECTROFISHIPC Objectives:
(1) To provide specimens for fish movements studies, population esticates, food habits, and radiation analysis; and (2) To determine the relative abundance of fishes vulnerable to electrofishing 258 187
4 in various parts of York Haven Pond.
Progress: Sa=pling was not atte=pted in February due to ice and high river flows. Data are currently being analyzed and tabulated for the 1978 report.
MOVEME?TTS OF FISHES Objective: To determine if fishes in waters receiving the TMINS effluent mix with fishes from other areas.
Progress: No sa=pling was atte=pted in February due to ice and high river flows. One tagged rock bass was recaptured by a fisherman.
It had moved 12.0 km downstream over York Haven Dam to the Brunner Island Steam Electric Station dische rge canal.
FOOD RGITS OF FISHES Objectives:
(1) To investigate food habits of the white sucker, rock bass, redbreast sunfish, smallmouth bass, and tessellated darter; and (2) To determine differences in food habits due to size of fish and location of capture.
Progress: Data are currently being analyzed and tabulated for the 1978 report.
CREEL SURVEY Objectives:
(1) To determine tne extent and success of sport fishing; and (2) To determine information on angler residence and use of catch.
258 188
5 Progress: Creel surveys were conducted on 8, 11, 24, and 27 February (Table 1) only at York Haven Generating Station due to ice t.nd high river flows. The seven anglers interviewed fished 6.75 hours8.680556e-4 days <br />0.0208 hours <br />1.240079e-4 weeks <br />2.85375e-5 months <br /> and caught two carp; both were released (Table 6).
The mean catch per effort was 0.30.
All the anglers interviewed were residents of York County. Most of the anglers reported they eat some of their catch.
AMBIENT WATER QUALITY Objective: To determine concentrations of selected water qtsality parameters in ambient river areas and the TMINS effluent.
Progress: Sampling was not atte=pted in Fr.aruary due to ice and high river ficws. Data are currently being analyzed and tabulated for the 1978 report.
DATA CODING Objective: To code data collected during 1974 through 1978 for those programs listed in the Generation Procedures.
Progress: The 1978 macroinvertebrate and ichthyoplankton entrain =ent data were transmitted to Metropolitan Edison Company; notification of delivery was obtained.
Ichthyoplankton far-field data for 1977 and 1978 were transmitted to Metropolitan Edison Co=pany La the form of computer cards. Data from 1978 seine, trapnet, and icpingement programs were coded, checked for quality assurance, and are awaiting transmission approval. Water quality and thermal plume data 258 189
6 for 1978 were coded. Programs currently being coded include population estimates 1978, creel survey 1978, and macroinvertebrate 1977.
