Florida Lake
Kandiyohi County, MinnesotaMesotrophic
Florida Lake comes in at a B on the grading rubric — a respectable showing for a Minnesota lake of its size and depth. With clarity and phosphorus scored, the sub-grades cluster within a letter of each other, pointing to stable conditions rather than one specific stressor.
Mesotrophic conditions dominate at Florida Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. A maximum depth of 40 ft puts Florida Lake in the middle of Minnesota's depth distribution. At 705 acres, Florida Lake fits the Minnesota median for monitored lakes, with 4.4 miles of shoreline. Within Kandiyohi County's 35 graded waters, Florida Lake sits at rank 6, near the top of the local distribution.
Zebra mussels have been documented at Florida Lake, which alters the filter-feeding balance and can paradoxically increase water clarity while disrupting the food web. The fishery includes walleye among the lake's 18 documented species — a notable draw for Minnesota anglers. A documented public access point at Florida Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. 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.

DNR Fisheries Survey Summary
16 surveys on file from MN DNR Fisheries. Most recent: 2024-07-15 (Standard Survey).
Top Species by Catch Rate
| Species | Avg CPUE | Avg Weight |

From the 2024-07-15 survey
A standard survey of Lake Florida was conducted in July 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 methodology…
