Betty Lake

Betty Lake earns a D — measurements through 2024 show persistent nutrient pressure that limits clarity through the summer. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. A maximum depth of 29 ft puts Betty Lake in the middle of Minnesota's depth distribution. The lake's 154 acres and 2.2 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Within Meeker County's 23 graded lakes, Betty Lake ranks 16 — below the local median, though not at the bottom.

No invasive species are currently listed at Betty Lake — the lake remains off the Minnesota infested-waters roster. The fishery includes walleye alongside the lake's other 15 documented species — a notable draw for Minnesota anglers. The lake lacks a documented public access point, so visitor use is limited. The lake has a partial ice record — 22 observed ice-outs, centered near Apr 8. 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.
