Kraemer Lake

Stearns County, MinnesotaMesotrophic

Kraemer Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

A TSI near 49 places Kraemer Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. A maximum depth of 30 ft puts Kraemer Lake in the middle of Minnesota's depth distribution. At 195 acres, Kraemer Lake fits the Minnesota median for monitored lakes, with 2.5 miles of shoreline. Kraemer Lake ranks 23 of 55 in Stearns County — solidly in the upper half of the local distribution.

Kraemer 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 14 documented species — a notable draw for Minnesota anglers. 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.
