Upper Egg Lake

On the scoring rubric Upper Egg Lake grades a D: clarity at 3.0 ft and 53 µg/L of phosphorus keep it in the lower bracket for Becker County. Secchi readings are the weakest of the three parameters, suggesting suspended sediment or algal biomass dominates the optical signal.

At a TSI of 61, Upper Egg Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. 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. Upper Egg Lake ranks 98 of 102 in Becker County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Upper Egg Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Upper Egg Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. A documented public access point at Upper Egg Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
