Sunset Pond

Sunset Pond sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. Secchi readings are the weakest of the three parameters, suggesting suspended sediment or algal biomass dominates the optical signal.

A TSI in the eutrophic range signals a lake doing what nutrient-loaded waters do — supporting an active algal community at the cost of clear water. Sunset Pond is a shallow lake at 11 ft maximum depth, which means it warms quickly, mixes constantly, and amplifies nutrient inputs. The lake is compact at 44 acres, with 3.5 miles of shoreline and little volume to buffer nutrient inputs. Among the 48 graded lakes in Dakota County, Sunset Pond sits at rank 20, above the county median.

Sunset Pond carries an invasive watermilfoil record — boat-launch decontamination and shoreline care matter more here than at uninfested lakes. The state fisheries records do not list documented species for Sunset Pond, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Sunset Pond — most use is by shoreline residents and their guests. Multiple sampling years from Minnesota PCA volunteers and partner agencies back the grade, so the letter should hold steady absent a major watershed shift.
