Auburn Dam
April 17, 2003
Sampling Gear: Daylight Electrofishing


On April 17 biologists from the Pennsylvania Fish and Boat Commission’s (PFBC) southeast region office conducted a daylight electrofishing survey of Auburn Dam. The purpose of the survey was to collect samples of largemouth bass and yellow perch for flesh contamination analysis, specifically PCB’s. Previous flesh contamination analyses have resulted in one meal per month consumption advisories on bluegill and brown bullhead caught from Auburn Dam as a result of PCB’s. The survey also allowed the sampling crew to produce information on largemouth bass abundance for comparison with other waters in the region.

During 1 hour and 38 minutes of electrofishing PFBC biologists collected 51 largemouth bass with 37 being greater than or equal 12 inches long and 20 being greater than or equal to 15 inches long. The largest bass was 18 inches long. Pennsylvania Fish and Boat Commission biologists typically compare bass populations between impoundments based upon the total catch of bass, the catch of bass > 12 inches, and the catch of bass > 15 inches per hour of electrofishing. In southeastern Pennsylvania the average total catch of bass is 50/hr, the catch of bass > 12 inches is 12/hr, and the catch of bass > 15 inches is 3.5/hr. At Auburn Dam the total catch rate of largemouth bass was 33 bass/hr. The catch rate of largemouth bass > 12 inches long was 21 bass/hr and the catch rate of largemouth bass > 15 inches long was 11 bass/hr. A quality largemouth bass population was clearly present in Auburn Dam.

The 163 acre impoundment on the Schuylkill River was constructed in 1950 as part of the Schuylkill River Desilting Project and is located between the towns of Auburn and Landingville in Schuylkill County.
