Sixth Crow Wing Lake
Hubbard County, MinnesotaMesotrophic
Sixth Crow Wing Lake comes in at a B on the grading rubric — a respectable showing for a Minnesota lake of its size and depth. 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.
A TSI near 47 places Sixth Crow Wing Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. The lake bottoms out at 40 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. At 346 acres, Sixth Crow Wing Lake fits the Minnesota median for monitored lakes, with 3.8 miles of shoreline. Within the 77 graded lakes of Hubbard County, Sixth Crow Wing Lake sits at rank 68, near the bottom of the county list.
No invasive species are currently listed at Sixth Crow Wing Lake — the lake remains off the Minnesota infested-waters roster. The fishery includes walleye alongside the lake's other 14 documented species — a notable draw for Minnesota anglers. A documented public access point at Sixth Crow Wing Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The lake has a partial ice record — 6 observed ice-outs, centered near Apr 15. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
