Sampling Technique - Towed Boat Electrofishing


Located in Franklin County, Falling Spring Branch can be characterized as a fertile limestone spring. Falling Spring Branch offers anglers diverse angling opportunities. Anglers may choose to fish for wild trout in the Catch and Release Fly-Fishing Only section or fish for stocked trout in either the Delayed Harvest Artificial Lures Only section or in the section open to angling under Statewide Regulations.

Anglers are fortunate to have a greenway along significant portions of Falling Spring Branch, which offers protection from the effects of development within the watershed as well as guaranteed access to the stream corridor. The Greenway Association and Trout Unlimited have been instrumental in securing these greenways and assisting with stream habitat improvement projects.

Biologists and technicians from the Pennsylvania Fish and Boat Commission Fisheries Management Division conducted a survey of three historic sites in the Catch and Release Fly-fishing Only Section of Falling Spring Branch in August. This survey will provide insight for future fisheries management plans.

Falling Spring Branch supports populations of wild rainbow and brown trout. Wild rainbow trout collected during the survey were between 2 and 21 inches in total length. Wild brown trout ranged from between 3 and 19 inches in total length. Other species found during the survey include white sucker, tiger trout, brook trout, pearl dace and redbreast sunfish. A summary table depicting the total trout caught during the survey is provided below.
