Goose Lake

Hennepin County, MinnesotaHypereutrophic

Goose Lake grades an F: water clarity, phosphorus, and chlorophyll-a all rate poorly, placing it among the most stressed lakes monitored in Minnesota. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

Hypereutrophic conditions mean the lake is operating at the upper end of the productivity scale, with all the bloom risk that implies. Goose Lake is a shallow lake at 8 ft maximum depth, which means it warms quickly, mixes constantly, and amplifies nutrient inputs. Goose Lake is small — 11 acres alongside 0.6 miles of shoreline — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Goose Lake sits at rank 69 of 95 in Hennepin County, in the lower half of the local distribution.

Goose Lake has no invasive species recorded in Minnesota state databases as of 2022, though prevention practices still apply at all access points. The fishery is panfish-dominated — bluegill, crappie, and sunfish among the 2 species documented for the lake. The lake lacks a documented public access point, so visitor use is limited. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.

DNR Fisheries Survey Summary

3 surveys on file from MN DNR Fisheries. Most recent: 2022-07-06 (Standard Survey).

Top Species by Catch Rate

CPUE = catch per unit effort, averaged across surveys (excludes juvenile shoreline seining). Higher CPUE = more abundant in standardized sampling.

Length Distributions

From the 2022-07-06 survey

Boundary Creek Pond is part of Fishing in the Neighborhood. It is an eleven-acre lake, and the maximum depth is 8 feet. The lake was last stocked in 2014 and the pier was removed in 2022. The City of Maple Grove has planned to replace it in 2023. Only 2 fish species were captured in 2022. Black Bullhead and Black…
