August Lake Fishing Regulations
August Lake follows Minnesota statewide fishing regulations — no lake-specific special rules in DNR records.
On the LakeGrade scale August Lake grades a B, with clarity at 4.7 ft and 13 µg/L of phosphorus placing it above the Minnesota median. Secchi readings are the weakest of the three parameters, suggesting suspended sediment or algal biomass dominates the optical signal.
A TSI near 48 places August Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. August Lake reaches 19 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 229 acres, August Lake fits the Minnesota median for monitored lakes, with 6.0 miles of shoreline. Within Lake County's 159 graded lakes, August Lake ranks 91 — below the local median, though not at the bottom.
