Christianson Lake
Lake County, MinnesotaEutrophic
On the scoring rubric Christianson Lake grades a D: clarity at 2.0 ft and 36 µg/L of phosphorus keep it in the lower bracket for Lake County. Secchi readings are the weakest of the three parameters, suggesting suspended sediment or algal biomass dominates the optical signal.
At a TSI of 61, Christianson Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. At only 8 ft deep, Christianson Lake is shallow — wind keeps the water column mixed and sediment resuspension drives phosphorus levels harder to manage. Christianson Lake covers 150 acres alongside 2.8 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Christianson Lake ranks 134 of 142 in Lake County — at the lower end of the locally monitored distribution.
No invasive species are currently listed at Christianson Lake — the lake remains off the Minnesota infested-waters roster. Walleye are documented at Christianson Lake, one of 5 fish species on record for the lake. A documented public access point at Christianson Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. 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.
