Trude Lake sits just upstream of the Turtle-Flambeau Flowage, giving owners access to thousands of acres of wild water while still maintaining a more controlled, residential home base.

In a region dominated by flowage-style water, Trude stands out as one of the stronger options due to its setting, scenery, and balance between quiet home-lake use and easy access to the larger system. For buyers looking in the Mercer/Turtle-Flambeau corridor, it consistently ranks near the top of the list.

This is a summary based on available information.

Trude Lake is known as a strong walleye and musky fishery with bass, pike, and panfish also available, benefiting from its connection to the Turtle‑Flambeau system. Anglers focus on points, reefs, and the narrows toward the flowage, using jigs, rigs, crankbaits, and big musky baits. The combination of lake structure and river influence creates multiple seasonal patterns, from weedline bites to deeper rock and current‑edge fish. Many anglers base on Trude and treat the Turtle‑Flambeau as an additional playground just downstream.
