The meandering 6.3-mile shoreline features points, bays, and narrows that give it strong visual interest and make it particularly appealing for paddling and small-boat cruising.

This is a summary based on available information.

Fishtrap and neighboring High Lake support a multi-species fishery highlighted by walleyes, muskies, bass, pike, and panfish, with the connecting channel allowing fish to move freely between basins. Weedlines, points, and channel edges between the two lakes are prime spots, especially in low-light windows and shoulder seasons. Clear water encourages many anglers to focus on 8–16 foot edges with jigs, live bait rigs, and smaller crankbaits, while muskies and pike patrol bars and saddles that link shallow and deep water. For cabin owners, Fishtrap Lake offers the sense of being on a small chain, with enough water and structure variety to stay interesting across seasons without feeling crowded.

I had AI give me the coordinates for the launches I had on file. They are not super accurate, but should give a rough idea of where you can find the landings. If no coordinates were available at all I didn't link to the map.
