Gaslyn Lake

Gaslyn Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. Of the three parameters, phosphorus is the worst — at 32 µg/L of phosphorus, it keeps the lake susceptible to algal blooms in warm years.

A TSI near 46 places Gaslyn Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. Gaslyn Lake is a shallow lake at 12 ft maximum depth, which means it warms quickly, mixes constantly, and amplifies nutrient inputs. At 161 acres, Gaslyn Lake fits the Wisconsin median for monitored lakes, with partial shoreline records. Gaslyn Lake ranks 60 of 70 in Burnett County — at the lower end of the locally monitored distribution.

An invasive species record — Chinese Mystery Snail — has been logged at Gaslyn Lake; Wisconsin DNR maintains the official infested-waters list. Bass fishing is part of the appeal: the species list runs to 3, anchored by largemouth and/or smallmouth bass. A documented public access point at Gaslyn Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The grade is supported by multiple sampling years from the Wisconsin DNR Citizen Lake Monitoring Network, giving the letter a reasonably stable foundation.
