Carlson-Tande Dam Lake vs Tolna Dam Lake
Water quality, depth, fish species, and recreation comparison.
Carlson-Tande Dam Lake has a higher water quality grade (C, Fair) than Tolna Dam Lake (D, Poor). Both are in Wisconsin.
Carlson-Tande Dam Lake and Tolna Dam Lake are both in North Dakota — a same-state head-to-head where the comparison comes down to lake-specific differences in depth, watershed, and monitoring history rather than the broader state-level water-quality regime. These two are within a letter of each other on the rubric — Carlson-Tande Dam Lake (C) versus Tolna Dam Lake (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.
