Lake of the Falls vs Turtle Flambeau Flowage Lake
Water quality, depth, fish species, and recreation comparison.
Lake of the Falls and Turtle Flambeau Flowage Lake both received the same overall water quality grade of B (Good). Both are in Iron County, Wisconsin.
Both Lake of the Falls and Turtle Flambeau Flowage Lake 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 of the Falls (B) versus Turtle Flambeau Flowage 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.

Verdict
Both lakes earn the same Grade B. The tiebreakers come down to clarity (Lake of the Falls: 5.4 ft, Turtle Flambeau Flowage Lake: 6 ft) and what you want from the lake. Lake of the Falls matches its peer on species count.
