About Lake Montesian
Lake Montesian offers the classic northern Wisconsin combo: northern pike and bass in a Green County setting that draws anglers and families alike, a intimate 10-acre lake reaching 15 feet at its deepest. Access is limited, which keeps boat traffic low — a plus for solitude seekers. Anglers primarily target Panfish. Note that invasive species (Curly-Leaf Pondweed, Hybrid Eurasian / Northern Water-Milfoil, Purple Loosestrife) have been documented here — clean your boat before leaving.

Full table →Fishing Tips
- ·Northern pike are ambush predators — target weed edges, fallen timber, and points with large spoons or swimbaits.
- ·Spring pike fishing (ice-out through June) can be outstanding as they move into shallow, warming bays to spawn.
- ·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.
