Bryant Lake
Hennepin County, MinnesotaMesotrophic
Bryant Lake sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.
A TSI near 50 places Bryant Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. Bryant Lake reaches 45 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 180 acres, Bryant Lake fits the Minnesota median for monitored lakes, with 3.4 miles of shoreline. Among the 95 graded lakes in Hennepin County, Bryant Lake ranks 14 — in the top quartile locally.
Zebra mussel presence at Bryant Lake means the lake's clarity numbers carry an asterisk — filtered water is not the same as nutrient-poor water. The fishery includes walleye alongside the lake's other 11 documented species — a notable draw for Minnesota anglers. Public access is available — the lake is on the Minnesota PCA public-access list. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.

From the 2023-08-21 survey
A targeted survey of nearshore fish species in Bryant Lake was conducted on August 21-22, 2023, by Index of Biological Integrity (IBI) Program staff. Sampling sites were evenly spaced around the lake, and each was sampled by backpack electrofishing and seining with a 50-foot or 15-foot seine, where possible. Backpack…
