Lords Lake
Pine County, MinnesotaLimited DataMesotrophic
Lords Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.
Mesotrophic conditions dominate at Lords Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. A maximum depth of 42 ft puts Lords Lake in the middle of Minnesota's depth distribution. At 527 acres, Lords Lake fits the Minnesota median for monitored lakes, with 7.2 miles of shoreline. Lords Lake ranks 9 of 20 in Pine County — solidly in the upper half of the local distribution.
Eurasian watermilfoil is established at Lords Lake, which can dampen recreational access and pressure the native plant community. Muskie are on the species list at Lords Lake, alongside the lake's 13 other documented fish. A documented public access point at Lords Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The lake has a partial ice record — 18 observed ice-outs, centered near Apr 20. 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.
