Howard Lake
Wright County, MinnesotaEutrophic
Howard Lake sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.
A TSI in the eutrophic range signals a lake doing what nutrient-loaded waters do — supporting an active algal community at the cost of clear water. Howard Lake reaches 39 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 745 acres, Howard Lake fits the Minnesota median for monitored lakes, with 4.7 miles of shoreline. Howard Lake ranks 29 of 64 in Wright County — solidly in the upper half of the local distribution.
Eurasian watermilfoil has been documented at Howard Lake, requiring shoreline management to keep dense mats from crowding native vegetation. The fishery includes walleye alongside the lake's other 16 documented species — a notable draw for Minnesota anglers. Public access is available — the lake is on the Minnesota PCA public-access list. The lake has a long ice-out record — 109 observations on file, with a median ice-out around Apr 13. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.

From the 2024-08-19 survey
A targeted survey of nearshore fish species in Howard Lake, was conducted on July 29-July 31st, 2024, by Area Fisheries 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 electrofishing was…
