Rose Valley Lake
Spring 2003


Rose Valley Lake

Rose Valley Lake is a 389 acre reservoir located in Lycoming County and is managed by the Pennyslvania Fish and Boat Commission for public fishing and boating. There are three public boat launches and motors are restricted to electric power only. Rose Valley Lake is in the Big Bass Program and all other species are under standard regulations for Commonwealth Inland Waters.

The 2003 field season got off to a good start when Fisheries Management Area 3 and Warmwater Unit personnel traveled to Rose Valley Lake to sample the walleye, yellow perch and chain pickerel populations with trapnets (click here for June 2003 report). Although the weather was cold, damp and sometimes downright miserable, the catches in our trapnets were good (see Table 1 below). Yellow perch were comparable to previous surveys with excellent numbers of larger fish. Walleye numbers were a little below the last survey (1997) but still there are good numbers of legal fish available for anglers. Chain pickerel seem to be declining to historic levels following the population boom of the late 1990’s.

Non-target species of note include bluegill, black crappie, largemouth bass and golden shiners. We will return to trapnet and night electrofish in late May to target these species when water temperatures warm into the range ideal for sampling these warmwater fish. Just for comparison, bluegill numbers were slightly below the last survey, but the catch of large 8+ inch bluegill is up. Black crappie remain down in Rose Valley Lake compared to the high numbers back in the mid-1980’s. The number of largemouth bass captured in trapnets was interesting. In general, bass are rarely captured by trapnets, however we caught 81 largemouth bass with 15 of them over legal size of 15 inches. Night electrofishing in May will show us more about the bass. Rose Valley Lake maintains a strong forage base of golden shiners of all sizes.
