Big Rice Lake vs Kitchi West Arm Lake

Water quality, depth, fish species, and recreation comparison.

Kitchi West Arm Lake has a higher water quality grade (B, Good) than Big Rice Lake (C, Fair). Both are in Beltrami County, Minnesota.

Both Big Rice Lake and Kitchi West Arm Lake sit in Minnesota. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. These two are within a letter of each other on the rubric — Big Rice Lake (C) versus Kitchi West Arm Lake (B). The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.

With grades this close, the choice between the two lakes turns on non-water-quality factors: depth, fish species, public access, distance from home. The per-lake pages below cover all of those.
