Hatch Lake

Hatch Lake sits at the top of the Minnesota PCA grading rubric with an A, a mark reached by the cleanest lakes in Minnesota. 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.

Trophically, Hatch Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. Hatch Lake is unusually deep for Minnesota at 88 ft, which buffers the lake against summer warming and helps the deep water stay oxygenated. The lake's 226 acres and 4.4 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Within Itasca County's 141 graded waters, Hatch Lake sits at rank 15, near the top of the local distribution.

Hatch Lake has no invasive species recorded in Minnesota state databases as of 2024, though prevention practices still apply at all access points. The fishery includes walleye alongside the lake's other 15 documented species — a notable draw for Minnesota anglers. No formal public access is documented at Hatch Lake — most use is by shoreline residents and their guests. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
