Plantagenet Lake

Plantagenet Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

Mesotrophic conditions dominate at Plantagenet Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. Plantagenet Lake is unusually deep for Minnesota at 65 ft, which buffers the lake against summer warming and helps the deep water stay oxygenated. At 2,531 acres, Plantagenet Lake is one of the larger lakes in Hubbard County, with 11.0 miles of shoreline supporting multiple distinct use patterns. Within the 77 graded lakes of Hubbard County, Plantagenet Lake sits at rank 65, near the bottom of the county list.

Plantagenet Lake is on the Minnesota infested-waters list for zebra mussels — boaters should follow clean-drain-dry protocols when moving gear to or from the lake. Muskie are on the species list at Plantagenet Lake, alongside the lake's 20 other documented fish. Public access is available — the lake is on the Minnesota PCA public-access list. The lake has a partial ice record — 12 observed ice-outs, centered near Apr 24. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
