General Fishing Information

Rainbow trout are usually targeted in the spring and early-summer shortly after they're stocked. Good baits to try are worms, minnows, and artificial natural baits (like Gulp or PowerBait) fished under a bobber. Spinners, small stickbaits, spoons and flies will also work especially in the flowing water where the upper Salmon River and power companies discharge canal enter the reservoir. Largemouth bass can be caught on Texas rigged worms, spinnerbaits and crankbaits worked along the shoreline.


Special fishing regulations apply (leaving DEC website to official Fishing Regulations Guide vendor website).

Fisheries Management

Lighthouse Hill Reservoir is stocked annually with approximately 4,050 year-old rainbow trout (8-9").
