Ghost Lake

Ghost Lake comes in at a B on the grading rubric — a respectable showing for a Minnesota lake of its size and depth.

A TSI near 40 places Ghost Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. A maximum depth of 30 ft puts Ghost Lake in the middle of Minnesota's depth distribution. The lake's 105 acres and 1.9 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Ghost Lake sits at rank 81 of 141 in Itasca County, in the lower half of the local distribution.

No invasive species are currently listed at Ghost Lake — the lake remains off the Minnesota infested-waters roster. The fishery includes walleye among the lake's 6 documented species — a notable draw for Minnesota anglers. Public access is available — the lake is on the Minnesota PCA public-access list. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
