George Lake
Kandiyohi County, MinnesotaMesotrophic
George Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Kandiyohi County. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.
A TSI near 40 places George Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. A maximum depth of 34 ft puts George Lake in the middle of Minnesota's depth distribution. At 228 acres, George Lake fits the Minnesota median for monitored lakes, with 2.7 miles of shoreline. Within Kandiyohi County's 35 graded waters, George Lake sits at rank 1, near the top of the local distribution.
Zebra mussel presence at George Lake means the lake's clarity numbers carry an asterisk — filtered water is not the same as nutrient-poor water. Walleye are documented at George Lake, one of 15 fish species on record for the lake. A documented public access point at George Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. Ice-out has been recorded 16 times at George Lake, with a median around Apr 14. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.

From the 2025-05-07 survey
A targeted survey was conducted on George Lake during early May of 2025 as part of the ongoing statewide Quality Sunfish Initiative. Ten standard lake survey trapnets were set at historical stations to target Bluegill and Black Crappie. Special regulations for several area lakes (Nest, Long by Hawick, Diamond, George…
