Little Wood Lake

Burnett County, WisconsinLimited DataEutrophic

Little Wood Lake comes in at a B on the grading rubric — a respectable showing for a Wisconsin lake of its size and depth.

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 23 ft puts Little Wood Lake in the middle of Wisconsin's depth distribution. The lake's 196 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. Little Wood Lake sits at rank 33 of 57 in Burnett County, in the lower half of the local distribution.

An invasive species record — Chinese Mystery Snail — has been logged at Little Wood Lake; Wisconsin DNR maintains the official infested-waters list. The fishery is bass-led, with 3 documented species across the lake's records. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
