Round Lake

Round 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.

Mesotrophic conditions dominate at Round Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. Round Lake reaches 20 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. Round Lake covers 127 acres alongside 1.7 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Round Lake sits at rank 10 of 16 in Morrison County, in the lower half of the local distribution.

No invasive species are currently listed at Round Lake — the lake remains off the Minnesota infested-waters roster. The fishery includes walleye alongside the lake's other 9 documented species — a notable draw for Minnesota anglers. A documented public access point at Round Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The lake has a partial ice record — 10 observed ice-outs, centered near Apr 17. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
