Sand Lake

Itasca County, MinnesotaMesotrophic

Sand Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Itasca County. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

Mesotrophic conditions dominate at Sand Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. At 60 ft of maximum depth, Sand Lake stratifies reliably through the summer — the hypolimnion stays cooler and clearer than the surface layer suggests. At 715 acres, Sand Lake fits the Minnesota median for monitored lakes, with 10.0 miles of shoreline. Sand Lake ranks 44 of 141 in Itasca County — solidly in the upper half of the local distribution.

Sand Lake is on the Minnesota infested-waters list for zebra mussels — boaters should follow clean-drain-dry protocols when moving gear to or from the lake. The state fisheries records do not list documented species for Sand Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Sand 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.

DNR Fisheries Survey Summary

2 surveys on file from MN DNR Fisheries. Most recent: 1986-07-17 (Standard Survey).

Top Species by Catch Rate

CPUE = catch per unit effort, averaged across surveys (excludes juvenile shoreline seining). Higher CPUE = more abundant in standardized sampling.
