About Rock Lake
Rock Lake is a prized trout lake in the Kenosha County Northwoods — cold, clear, and ideal for fly fishing, a intimate 44-acre lake reaching 33 feet at its deepest. The lake has public boat landing access, making it easy to launch for a day on the water. Anglers primarily target Largemouth Bass. Note that invasive species (Eurasian Water-Milfoil, Purple Loosestrife) 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.
