About Grenlie Lake
Grenlie Lake is a consistent bass fishery tucked into Waupaca County — the kind of lake that rewards anglers who know it, a intimate 6-acre lake reaching 40 feet at its deepest. Access is limited, which keeps boat traffic low — a plus for solitude seekers. Anglers target Largemouth Bass and Panfish. Note that invasive species (Purple Loosestrife) have been documented here — clean your boat before leaving.

Full table →Fishing Tips
- ·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.
