Fireman'S Lake
Carver County, MinnesotaMesotrophic
Fireman'S Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.
A TSI near 46 places Fireman'S Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. A maximum depth of 23 ft puts Fireman'S Lake in the middle of Minnesota's depth distribution. At 9 acres, Fireman'S Lake sits below the Minnesota median: a small water where shoreline activity has an outsized effect on water quality. Within Carver County's 40 graded waters, Fireman'S Lake sits at rank 6, near the top of the local distribution.
Fireman'S Lake carries an invasive watermilfoil record — boat-launch decontamination and shoreline care matter more here than at uninfested lakes. The fishery is panfish-dominated — bluegill, crappie, and sunfish among the 8 species documented for the lake. The lake lacks a documented public access point, so visitor use is limited. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.

Firemen's Pond is a 9-acre lake in the middle of downtown Chaska. In 2016 the City of Chaska completed a project that upgraded the surrounding park which has increased access to a large portion of the shoreline for fishing. A portion of the pond is designated for swimming and sits adjacent to a playground and a picnic…
