Two Rivers Lake
Stearns County, MinnesotaLimited DataMesotrophic
Two Rivers Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season.
Mesotrophic conditions dominate at Two Rivers Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. Two Rivers Lake is unusually deep for Minnesota at 63 ft, which buffers the lake against summer warming and helps the deep water stay oxygenated. Two Rivers Lake covers 583 acres alongside 6.6 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Two Rivers Lake ranks 18 of 55 in Stearns County — solidly in the upper half of the local distribution.
Two Rivers Lake is on the watch list for starry stonewort, an invasive macroalga that is difficult to control once established. The fishery includes walleye among the lake's 17 documented species — a notable draw for Minnesota anglers. A documented public access point at Two Rivers Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. Ice-out has been recorded 5 times at Two Rivers Lake, with a median around Apr 7. 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 2024-07-08 survey
A targeted survey of nearshore fish species in Two Rivers Lake was conducted beginning July 8th, 2024, by Index of Biological Integrity (IBI) Program staff. Sampling sites were evenly spaced around the lake, and each was sampled by backpack electrofishing and seining with a 50-foot or 15-foot seine, where possible.…
