The lake has public boat landing access, making it easy to launch for a day on the water. The fishery includes Largemouth Bass, Panfish, and Trout. Note that invasive species (Curly-Leaf Pondweed, Eurasian Water-Milfoil) have been documented here — clean your boat before leaving.

Full table →Fishing Tips
- ·Trout hold in the deepest, coolest water during summer. Early morning stillwater fishing or bottom rigs near spring seeps is productive.
- ·Largemouth bass relate to shallow structure. Work topwater lures at dawn in summer, then switch to soft plastics rigged weedless around lily pads and fallen wood.
- ·Bluegill and crappie stack up in 8–15 ft of water near weedlines. Small jigs tipped with a waxworm are hard to beat.
- ·Panfish are often excellent for kids and beginners — look for them around any dock or submerged brush piles.
