East Pike Lake
Cook County, MinnesotaLimited DataMesotrophic
East Pike Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.
A TSI near 41 places East Pike Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. East Pike Lake reaches 40 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 554 acres, East Pike Lake fits the Minnesota median for monitored lakes, with 9.4 miles of shoreline. East Pike Lake ranks 63 of 128 in Cook County — solidly in the upper half of the local distribution.
No invasive species are currently listed at East Pike Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for East Pike Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at East Pike Lake — most use is by shoreline residents and their guests. 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 2025-08-08 survey
Temperature and dissolved oxygen (DO) measurements were collected from the deepest basin in East Pike Lake on August 8th, 2025, to evaluate the quantity and quality of cold, oxygenated water (i.e., oxythermal habitat) available to Lake Whitefish, the most sensitive coldwater species present in this lake (Cisco, also…
