White Swan Lake

White Swan Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

A TSI near 41 places White Swan Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. A maximum depth of 19 ft puts White Swan Lake in the middle of Minnesota's depth distribution. White Swan Lake covers 165 acres alongside 3.6 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Within Itasca County's 141 graded lakes, White Swan Lake ranks 82 — 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. Walleye are documented at White Swan Lake, one of 9 fish species on record for the lake. 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. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
