MLLPOA is exploring a QSI for Maple Lake
Sunfish numbers in Maple Lake are relatively low; however the size structure is above average for the area. Historical summer trap net surveys rarely sample Sunfish over 8 inches and do not appear to represent the true size structure of the Bluegill population. Recent studies found that targeted sampling around spawning time appears to give a better representation of the size structure of the Sunfish population. In 2015, a spring targeted survey sampled 614 Sunfish ranging in length from 3.4 – 9.8 inches with an average length of 6.5 inches. Seventy-two percent of the Sunfish sampled were longer than 6 inches and 12% were longer than 8 inches. Growth is average taking about 4 years to reach 6 inches and 6 years to reach 8 inches. Previous success on other lakes with a reduced bag leads us to believe that by reducing the bag limit to 5 or 10 will help protect and possibly improve the existing size structure.

Walleye Stocking 2020
The DNR completed their stocking program in Maple Lake on Friday October 9, 2020. This year the fish were released into Little Maple. The amount of fish was 396 pounds. This amount is based on the littoral zone of the lake which is 396 acres. The stocking program calls for 1 pound of fingerling Walleye per acre.
The MN DNR defines “Littoral Zone” as the shallow transition zone between dry land and the open water area of the lake. In Minnesota waters, the littoral zone extends from the shore to a depth of about 15 feet, depending on water clarity. The shallow water, abundant light, and nutrient-rich sediment provide ideal conditions for plant growth. Aquatic plants, in turn, provide food and habitat for many animals such as fish, frogs, birds, muskrats, turtles, insects, and snails.
Mike Polencheck works with the MN DNR to bring this program to Maple Lake. The lake association is on an “every other year” cycle with the DNR. As you recall, the ML-LPOA paid for Walleye stocking in 2019. This year, the DNR paid for the stock. In 2021 the ML-POA will pay.
400lbs of Walleye fingerling were introduced to Maple Lake at the Hwy 55 Beach access.
*Future stocking plans include MN DNR stocking our lake with Walleye Fry on even years. And MLLPOA stocking fingerling on odd years
