South Lindstrom Lake
Chisago County, MinnesotaEutrophic
South Lindstrom Lake comes in at a B on the grading rubric — a respectable showing for a Minnesota lake of its size and depth. Clarity is the limiting factor — phosphorus is reasonable but suspended particles or algal cells keep water transparency below Minnesota norms.
Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. South Lindstrom Lake reaches 34 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. The lake's 455 acres and 3.9 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Among the 31 graded lakes in Chisago County, South Lindstrom Lake sits at rank 10, above the county median.
South Lindstrom Lake carries an invasive watermilfoil record — boat-launch decontamination and shoreline care matter more here than at uninfested lakes. Walleye are documented at South Lindstrom Lake, one of 14 fish species on record for the lake. A documented public access point at South Lindstrom Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. Ice-out has been recorded 6 times at South Lindstrom Lake, with a median around Apr 15. The grade is supported by multiple sampling years from Minnesota PCA volunteers and partner agencies, giving the letter a reasonably stable foundation.

From the 2022-07-18 survey
South Lindstrom Lake is a moderately fertile 499-acre lake located in southern Chisago County bordering the city of Lindstrom. The lake is broadly connected to Chisago Lake by a natural channel. The connection between the two lakes facilitates fish movement and the two lakes are considered one for management purposes.…
