Arvilla Lake

Arvilla Lake grades an F: water clarity, phosphorus, and chlorophyll-a all rate poorly, placing it among the most stressed lakes monitored in Minnesota. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

Hypereutrophic conditions mean the lake is operating at the upper end of the productivity scale, with all the bloom risk that implies. Arvilla Lake is a shallow lake at 9 ft maximum depth, which means it warms quickly, mixes constantly, and amplifies nutrient inputs. At 138 acres, Arvilla Lake fits the Minnesota median for monitored lakes, with 2.3 miles of shoreline. Arvilla Lake ranks 20 of 23 in Meeker County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Arvilla Lake — the lake remains off the Minnesota infested-waters roster. 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. Ice-out has been recorded 19 times at Arvilla Lake, with a median around Apr 7. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
