Round Lake

Round Lake earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. With clarity and phosphorus scored, the sub-grades cluster within a letter of each other, pointing to stable conditions rather than one specific stressor.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. At 72 acres, Round Lake sits below the Minnesota median: a small water where shoreline activity has an outsized effect on water quality. Round Lake ranks 13 of 49 in Ramsey County — solidly in the upper half of the local distribution.

Eurasian watermilfoil is established at Round Lake, which can dampen recreational access and pressure the native plant community. The state fisheries records do not list documented species for Round Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. A documented public access point at Round Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. Ice-out has been recorded 7 times at Round Lake, with a median around Apr 8. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
