Rates come from standard DNR survey gear (gill nets, trap nets, electrofishing), judged against statewide benchmarks for the same gear, so the same number of fish per net can read differently for two species. Where the standard gear can't count a species reliably, only presence and size are listed. Typical is the middle fish of those measured. Open a row for the full length spread, survey by survey.

How to fish Fifteen Lake through the year

Northern pike

Spring
Pike are in the shallow bays and along new weed growth. At 10 ft of clarity, fish them deeper and lighter than usual.
Early summer
Pike are on the outside weed edge and points.
Summer
Pike are on the deep weed edge and points near the coolest water they can find. With 64% of this lake 15 ft or shallower, the weed edge is the main event.
Fall
Pike are on the last green weeds and the breaks beside them, feeding heavily as the water drops.

Walleye

Spring
Walleye are shallow, on and just off the spawning flats and the first green weeds. At 10 ft of clarity, fish them deeper and lighter than usual.
Early summer
Walleye are setting up on the outside weed edge, points and shallow structure.
Summer
Walleye are working the weed edge, points and any wind-blown structure. With 64% of this lake 15 ft or shallower, the weed edge is the main event.
Fall
Walleye are packing onto the sharpest breaks and points as the water cools, in big schools with short windows.

The lake's maximum depth is approximately 24 feet and has a history of infrequent winterkills. There is a DNR maintained public access on the north shore. In June 2024, the fish community was assessed with night electrofishing, six gill nets, and nine trap nets.

Northern Pike have been historically abundant in Lake Fifteen, and this was also the case in 2024. Pike had an average length of just over 21 inches, with the largest measuring 37 inches.

Read the full DNR narrative

Unlike Northern Pike, Walleye abundance in Lake Fifteen has been historically low, despite consistent stocking of Walleye fry. Only three Walleyes were caught during the survey in 2024. Those captured had an average length of 21 inches, and a maximum length of 25 inches.

Bluegill abundance was lower than past surveys, with fish averaging 5.5 inches long. Although fish up to 8 inches were measured, most Bluegill were less than 7.5 inches long.

This survey was the first time night electrofishing for Largemouth Bass was completed in Lake Fifteen. The average length of Largemouth Bass sampled was 13 inches. The largest Bass captured was just over 20 inches.
