Plum Lake

View of Plum Lake, the 1108 acre lake in St. Germain, Wisconsin

Plum Lake is a large, deep, clear 1,100-plus-acre lake west of St. Germain, widely regarded as one of the premier lakes in the area.

With excellent clarity, substantial depth, long stretches of natural shoreline, and low shoreline density for its size, Plum delivers true big-water scenery without the intensity of busier resort chains. Its central location—about 10 minutes to St. Germain and roughly 25 minutes to Eagle River, Minocqua, and Boulder Junction—makes it uniquely positioned: quiet and scenic, yet regionally accessible. For buyers seeking high water quality, privacy, and scale without sacrificing convenience, Plum consistently ranks near the top of the list.

Times are approximate. I just took a rough average from different points around the lake.

This is a summary based on available information.

Plum Lake supports the usual mix of walleyes, muskies, bass, pike, and panfish that favor deeper, clearer Northwoods waters. Anglers often work offshore structure, drop‑offs, and mid‑lake bars with jigs, rigs, and deep‑running crankbaits, especially when targeting walleyes and smallmouth bass. Clear water pushes many fish deeper during the day, so dawn, dusk, and nighttime trolling or casting can be especially productive. The relatively light development and lower boat pressure compared to busier chains give patient anglers room to explore and refine subtle patterns.

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.
