Bass Lake
Becker County, MinnesotaMesotrophic
Bass Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. Clarity is the limiting factor — phosphorus is reasonable but suspended particles or algal cells keep water transparency below Minnesota norms.
The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. A maximum depth of 28 ft puts Bass Lake in the middle of Minnesota's depth distribution. The lake's 204 acres and 3.3 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Bass Lake ranks 41 of 93 in Becker County — solidly in the upper half of the local distribution.
No invasive species are currently listed at Bass Lake — the lake remains off the Minnesota infested-waters roster. The fishery includes walleye alongside the lake's other 9 documented species — a notable draw for Minnesota anglers. A documented public access point at Bass Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The lake has a long ice-out record — 31 observations on file, with a median ice-out around Apr 22. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.
