Gaskin Lake
Cook County, MinnesotaLimited DataMesotrophic
Gaskin Lake comes in at a B on the grading rubric — a respectable showing for a Minnesota lake of its size and depth. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.
Mesotrophic conditions dominate at Gaskin Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. The lake's 82 ft maximum depth is in the upper tier for Minnesota — deep enough for cold-water fish to find refuge in summer. The lake's 372 acres and 12.9 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Gaskin Lake ranks 65 of 137 in Cook County — solidly in the upper half of the local distribution.
Gaskin Lake has no invasive species recorded in Minnesota state databases as of 2025, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Gaskin 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.
