Stone Lake

Stone Lake comes in at a B on the grading rubric — a respectable showing for a Minnesota lake of its size and depth.

A TSI near 43 places Stone Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. The lake bottoms out at 30 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. At 101 acres, Stone Lake fits the Minnesota median for monitored lakes, with 1.7 miles of shoreline. Stone Lake ranks 7 of 40 in Carver County, putting it in the upper tier of locally monitored lakes.

Eurasian watermilfoil is established at Stone Lake, which can dampen recreational access and pressure the native plant community. Stone Lake's fishery is anchored by muskellunge, with 7 documented species in total — a destination water for muskie anglers. The lake lacks a documented public access point, so visitor use is limited. The lake has a partial ice record — 17 observed ice-outs, centered near Mar 30. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
