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.
Mesotrophic conditions dominate at East Pike Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. East Pike Lake reaches 40 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. East Pike Lake covers 554 acres alongside 9.4 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. East Pike Lake ranks 63 of 128 in Cook County — solidly in the upper half of the local distribution.
East Pike Lake has no invasive species recorded in Minnesota state databases as of 2024, though prevention practices still apply at all access points. 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. The lake lacks a documented public access point, so visitor use is limited. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
