We conducted electrofishing surveys at 15 representative stations during June and July
2007 over approximately 27 km of Tenmile Creek and its South Fork in Greene Co., PA.
At each station, areal dimensions were recorded, selected water quality parameters
analyzed, and the site was georeferenced. A total of 10,094 fishes representing seven
families, 37 species, and four hybrids were collected over the entire survey. Percids and
minnows dominated riffle areas while the runs and pools harbored catastomids, minnows,
and centrarchids. We did not capture any state “Species of Special Concern”. Voucher
collections from all stations were preserved and stored in the fish museum at California
University of Pennsylvania. All stations exhibited pH values in excess of 8.0 and
elevated conductivity levels ranging from 440 to 4,500 μS/cm, a likely result of
discharges from mine drainage and municipal wastewater treatment facilities scattered
throughout the watershed.
