Clear Lake 2

The LakeGrade rubric puts Clear Lake 2 at a C: clarity at 131.2 ft, 61 µg/L of phosphorus, and a TSI of 43 signal an intermediate trophic state. Phosphorus is the parameter holding the grade back — runoff from the surrounding watershed appears to keep nutrient levels elevated through the summer.

Mesotrophic conditions dominate at Clear Lake 2: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake's surface area is not consistently recorded across state datasets — physical context remains partial. Among the 10 graded lakes in Goodhue County, Clear Lake 2 sits at rank 5, above the county median.

Clear Lake 2 has no invasive species recorded in Minnesota state databases as of 2025, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Clear Lake 2, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The lake lacks a documented public access point, so visitor use is limited. Multiple sampling years from Minnesota PCA volunteers and partner agencies back the grade, so the letter should hold steady absent a major watershed shift.
