Ninth Crow Wing Lake

Ninth Crow Wing Lake comes in at a B on the grading rubric — a respectable showing for a Minnesota lake of its size and depth. Clarity is the limiting factor — phosphorus is reasonable but suspended particles or algal cells keep water transparency below Minnesota norms.

A TSI near 44 places Ninth Crow Wing Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. At 65 ft of maximum depth, Ninth Crow Wing Lake stratifies reliably through the summer — the hypolimnion stays cooler and clearer than the surface layer suggests. The lake's 232 acres and 3.7 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Within Hubbard County's 77 graded lakes, Ninth Crow Wing Lake ranks 53 — below the local median, though not at the bottom.

No invasive species are currently listed at Ninth Crow Wing Lake — the lake remains off the Minnesota infested-waters roster. The fishery includes walleye alongside the lake's other 15 documented species — a notable draw for Minnesota anglers. No formal public access is documented at Ninth Crow Wing Lake — most use is by shoreline residents and their guests. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
