Parkers Lake
Hennepin County, MinnesotaEutrophic
Parkers Lake earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.
At a TSI of 54, Parkers Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. A maximum depth of 37 ft puts Parkers Lake in the middle of Minnesota's depth distribution. Parkers Lake covers 100 acres alongside 1.8 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Among the 95 graded lakes in Hennepin County, Parkers Lake ranks 20 — in the top quartile locally.
Eurasian watermilfoil has been documented at Parkers Lake, requiring shoreline management to keep dense mats from crowding native vegetation. The fishery is bass-led, with 9 documented species across the lake's records. Public access is available — the lake is on the Minnesota PCA public-access list. The lake has a partial ice record — 19 observed ice-outs, centered near Apr 3. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.

From the 2017-06-12 survey
Parkers Lake is a 100-acre lake with a maximum depth of 37 feet, located in central Hennepin County, in the city of Plymouth. Parkers Lake is primarily managed for Largemouth Bass, but also supports catchable populations of Bluegill and Northern Pike. A Standard Survey (trap nets and gill nets) was conducted on…
