White Swan Lake

Itasca County, MinnesotaLimited DataMesotrophic

White Swan Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. White Swan Lake reaches 19 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. The lake's 165 acres and 3.6 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 Itasca County's 141 graded lakes, White Swan Lake ranks 80 — below the local median, though not at the bottom.

White Swan Lake has no invasive species recorded in Minnesota state databases as of 2024, though prevention practices still apply at all access points. The fishery includes walleye among the lake's 9 documented species — a notable draw for Minnesota anglers. The lake lacks a documented public access point, so visitor use is limited. The lake has a partial ice record — 9 observed ice-outs, centered near Apr 13. 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.
