Loiten Lake

Loiten Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season.

A TSI near 42 places Loiten Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. The lake bottoms out at 49 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. At 94 acres, Loiten Lake sits below the Minnesota median: a small water where shoreline activity has an outsized effect on water quality. Among the 187 graded lakes in St. Louis County, Loiten Lake ranks 43 — in the top quartile locally.

Loiten Lake has no invasive species recorded in Minnesota state databases as of 2023, though prevention practices still apply at all access points. The fishery is bass-led, with 3 documented species across the lake's records. 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.
