Fish Species:

Lake Trout, Rainbow Trout, Smallmouth Bass, Largemouth Bass


Sylvia Lake is not only deep, it has very steep sides with limited near shore habitat. Smallmouth bass are abundant and can be caught along most of the shoreline area where steep drops and rock rubble habitat abounds. Largemouth bass are present, but prime habitat is somewhat restricted to the South end near the outlet. Lake trout are native stocks whereas the rainbow trout are stocked annually. Fishing deep will be effective for both species, but the rainbows have been known to feed at the surface even in the summer.
