Manuella Lake

On the LakeGrade scale Manuella Lake grades a B, with clarity at 10.0 ft and phosphorus readings still being added placing it above the Minnesota median.

A TSI near 44 places Manuella Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. At 51 ft of maximum depth, Manuella Lake stratifies reliably through the summer — the hypolimnion stays cooler and clearer than the surface layer suggests. At 293 acres, Manuella Lake fits the Minnesota median for monitored lakes, with 3.0 miles of shoreline. Manuella Lake ranks 2 of 23 in Meeker County, putting it in the upper tier of locally monitored lakes.

Manuella Lake carries an invasive watermilfoil record — boat-launch decontamination and shoreline care matter more here than at uninfested lakes. Walleye are documented at Manuella Lake, one of 16 fish species on record for the lake. Public access is available — the lake is on the Minnesota PCA public-access list. The lake has a partial ice record — 11 observed ice-outs, centered near Apr 11. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
