Little Sand Lake

On the LakeGrade scale Little Sand Lake grades a B, with clarity at 8.2 ft and 27 µg/L of phosphorus placing it above the Minnesota median. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

Mesotrophic conditions dominate at Little Sand Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. The lake bottoms out at 19 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. At 353 acres, Little Sand Lake fits the Minnesota median for monitored lakes, with 3.7 miles of shoreline. Within Itasca County's 141 graded lakes, Little Sand Lake ranks 94 — below the local median, though not at the bottom.

Zebra mussel presence at Little Sand Lake means the lake's clarity numbers carry an asterisk — filtered water is not the same as nutrient-poor water. Walleye are documented at Little Sand Lake, one of 13 fish species on record for the lake. A documented public access point at Little Sand Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
