Dynamite Lake
Langlade County, WisconsinLimited DataMesotrophic
Dynamite Lake sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. 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.
A TSI near 44 places Dynamite Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. The lake bottoms out at 28 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. At 100 acres, Dynamite Lake fits the Wisconsin median for monitored lakes, with partial shoreline records. Dynamite Lake ranks 31 of 32 in Langlade County — at the lower end of the locally monitored distribution.
An invasive species record — Rusty Crayfish — has been logged at Dynamite Lake; Wisconsin DNR maintains the official infested-waters list. The fishery is bass-led, with 3 documented species across the lake's records. A documented public access point at Dynamite Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
