Boom Lake
Oneida County, WisconsinLimited DataOligotrophic
On the LakeGrade scale Boom Lake grades a B, with clarity at 14.8 ft and phosphorus readings still being added placing it above the Wisconsin median. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.
Trophically, Boom Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. Boom Lake reaches 30 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. The lake's 365 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. Boom Lake sits at rank 98 of 140 in Oneida County, in the lower half of the local distribution.
An invasive species record — Chinese Mystery Snail — has been logged at Boom Lake; Wisconsin DNR maintains the official infested-waters list. Walleye are documented at Boom Lake, one of 6 fish species on record for the lake. Public access is available — the lake is on the Wisconsin DNR public-access list. 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.
