Wright Lake
Otter Tail County, MinnesotaLimited DataOligotrophic
Wright Lake comes in at a B on the grading rubric — a respectable showing for a Minnesota lake of its size and depth.
Trophically, Wright Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. A maximum depth of 32 ft puts Wright Lake in the middle of Minnesota's depth distribution. At 67 acres, Wright Lake sits below the Minnesota median: a small water where shoreline activity has an outsized effect on water quality. Wright Lake sits at rank 62 of 97 in Otter Tail County, in the lower half of the local distribution.
Zebra mussels have been documented at Wright Lake, which alters the filter-feeding balance and can paradoxically increase water clarity while disrupting the food web. Walleye are documented at Wright Lake, one of 14 fish species on record for the lake. A documented public access point at Wright Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
