Unnamed Lake

On the scoring rubric Unnamed Lake grades a D: clarity at 1.3 ft and 78 µg/L of phosphorus keep it in the lower bracket for Wright County. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

The hypereutrophic status — TSI 70 — reflects sustained heavy nutrient loading from the surrounding watershed and frequent algal pressure. The lake bottoms out at 38 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. At 97 acres, Unnamed Lake sits below the Minnesota median: a small water where shoreline activity has an outsized effect on water quality. Unnamed Lake sits at rank 45 of 64 in Wright County, in the lower half of the local distribution.

Zebra mussels have been documented at Unnamed Lake, which alters the filter-feeding balance and can paradoxically increase water clarity while disrupting the food web. The fishery includes walleye alongside the lake's other 17 documented species — a notable draw for Minnesota anglers. Public access is available — the lake is on the Minnesota PCA public-access list. Ice-out has been recorded 7 times at Unnamed Lake, with a median around Apr 13. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
