Lake Nokomis vs Tomahawk Riverlake Nokomis

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

Lake Nokomis has a higher water quality grade (C, Fair) than Tomahawk Riverlake Nokomis (D, Poor). Both are in Oneida County, Wisconsin.

Both Lake Nokomis and Tomahawk Riverlake Nokomis sit in Wisconsin. 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 — Lake Nokomis (C) versus Tomahawk Riverlake Nokomis (D). 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.
