Schultz Lake

On the LakeGrade scale Schultz Lake grades a B, with clarity at 8.5 ft and 20 µg/L of phosphorus placing it above the Minnesota median. Secchi readings are the weakest of the scored parameters, suggesting suspended sediment or algal biomass dominates the optical signal.

A TSI near 47 places Schultz Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. 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. Schultz Lake ranks 3 of 36 in Dakota County, putting it in the upper tier of locally monitored lakes.

Eurasian watermilfoil is established at Schultz Lake, which can dampen recreational access and pressure the native plant community. The state fisheries records do not list documented species for Schultz Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Schultz Lake — 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.
