Dog Lake

Dog Lake comes in at a B on the grading rubric — a respectable showing for a Wisconsin lake of its size and depth. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

A TSI near 45 places Dog Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. A maximum depth of 22 ft puts Dog Lake in the middle of Wisconsin's depth distribution. The lake's 202 acres and partial shoreline records put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Dog Lake ranks 107 of 140 in Oneida County — at the lower end of the locally monitored distribution.

Dog Lake has at least one documented invasive species (Rusty Crayfish), so boaters and anglers should observe clean-drain-dry steps when leaving the lake. The fishery includes walleye alongside the lake's other 6 documented species — a notable draw for Wisconsin anglers. 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.
