Variety Lake

Cass County, MinnesotaLimited DataMesotrophic

On the LakeGrade scale Variety Lake grades a B, with clarity at 10.5 ft and phosphorus readings still being added placing it above the Minnesota median. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. Variety Lake reaches 29 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 160 acres, Variety Lake fits the Minnesota median for monitored lakes, with 2.7 miles of shoreline. Within Cass County's 133 graded lakes, Variety Lake ranks 97 — below the local median, though not at the bottom.

No invasive species are currently listed at Variety Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Variety Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The lake lacks a documented public access point, so visitor use is limited. 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 1987-07-06 survey

The gillnet catch of northern pike (20.4/GN) indicates a high population. The 1981 and 1967 assessments catch of northern pike were 7.8 and 14.3 respectively. Quality size fish were present and growth rates were good. The bulk of northern pike ranged in length from 16 to 21 inches.The trapnet catch of bluegill was…
