Andrew Lake
Kandiyohi County, MinnesotaLimited DataMesotrophic
Andrew Lake sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year.
The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. A maximum depth of 26 ft puts Andrew Lake in the middle of Minnesota's depth distribution. The lake's 759 acres and 4.7 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Andrew Lake ranks 10 of 35 in Kandiyohi County — solidly in the upper half of the local distribution.
Andrew Lake is on the Minnesota infested-waters list for zebra mussels — boaters should follow clean-drain-dry protocols when moving gear to or from the lake. Walleye are documented at Andrew Lake, one of 16 fish species on record for the lake. Public access is available — the lake is on the Minnesota PCA public-access list. Ice-out has been recorded 8 times at Andrew Lake, with a median around Apr 8. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.

From the 2024-06-24 survey
A standard survey of Lake Andrew was conducted in late June of 2024. A targeted survey is generally used for sampling a specific kind of fish or time of year (i.e., spawning season, fall season, etc.) unlike a standard survey which samples a wider range of fish species during the summer months using standard…
