Beaverdam Run Reservoir

Beaverdam Run Reservoir is a 360-acre impoundment in Cambria County that is owned by Highland Sewer and Water Authority. It was opened to public fishing in July of 2000 through the efforts of many parties including Highland Sewer and Water Authority, Beaverdam Conservation Group, Southern Alleghenies Conservancy, and the Pennsylvania Fish and Boat Commission. Big Bass and Panfish Enhancement regulations have been used on the impoundment since its opening. 

Beaverdam Run Reservoir is a very infertile impoundment that had a pH of 6.6 and alkalinity of 2 mg/l during PFBC survies in April and May, 2001. The fish populations in Beaverdam Run Reservoir were reflective of the unproductive water.

Brown bullheads and yellow perch were the most abundant species. Brown bullheads were abundant and available in quality sizes with 93% greater than 10 inches. Beaverdam Run Reservoir would be an excellent lake to fish for bullheads. Yellow perch were collected in high numbers, but 87% of them were between 6 and 8 inches long. Seventy-three legal (9 inches or greater) yellow perch were captured including five perch between 13-15 inches. Bluegills, black crappie, and rock bass were collected in low numbers but quality-sized fish were present.

Total number of bass collected was low with 51 largemouth bass and 5 smallmouth bass. However, nice bass can be found in Beaverdam Run Reservoir. Of the 51 largemouth bass we captured, 63% were greater than 12 inches and 49% were greater than 15 inches including 12 fish greater than 18 inches long. Anglers may not catch many bass in Beaverdam Run Reservoir, but they may hook a trophy.

One interesting finding was the collection of an American eel near the mouth of Big Cedar Run. The American eel is native to the Susquehanna River and Delaware River drainages in Pennsylvania, but is not native to the Ohio River drainage, which includes Beaverdam Run Reservoir. The American eel was over 36 inches long.

Beaverdam Run Reservoir provides angling opportunities for bullheads, yellow perch, and largemouth bass. Low densities of smallmouth bass, bluegill, black crappie, and rock bass also exist in the lake. The infertile nature of Beaverdam Run Reservoir is a major factor limiting the fish populations in the lake. All information collected during this survey will be used to develop a fisheries management plan for the lake.
