Why Bass Lake has no grade

We grade a lake only when its monitoring record clears the evidence bar: at least three phosphorus or chlorophyll-a samples in the last ten years, scored against EPA National Lakes Assessment thresholds for this lake’s ecoregion. For Bass Lake, the only measurement available is water clarity, which is not a water-quality indicator on its own — EPA's National Lakes Assessment does not grade clarity. Sampling here has recorded water clarity, phosphorus and algae (chlorophyll-a).

Not Rated is not an F. It is EPA Integrated Reporting Category 3 — insufficient information. The water here may be excellent or poor; nobody has measured enough of it to say. Everything below that has been measured is still reported on this page.

Sampling is run by MPCA and volunteer programs, and published through the EPA Water Quality Portal. Read the full grading methodology.

Bass Lake is a 126-acre lake in Becker County, Minnesota with a maximum depth of 50 feet. Limited fish-species data available. Public access is available with 1 public boat landing.

CPUE = catch per unit effort, averaged across surveys (excludes juvenile shoreline seining). Higher CPUE = more abundant in standardized sampling.

From the 1987-08-10 survey

BLUEGILL, NORTHERN PIKE AND LARGEMOUTH BASS NUMBERS ARE ALL ABOVE STATE AND LOCAL MEDIANS. YELLOW BULLHEAD NUMBERS ARE OVER TWICE THE STATE AND LOCAL AVERAGES WITH YELLOW PERCH NUMBERS FALLING BELOW BOTH OF THE MEDIANS.
