H.S. Truman Res. Nr. Dam Lake vs Pomme de Terre L. Lake

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

H.S. Truman Res. Nr. Dam Lake has a higher water quality grade (C, Fair) than Pomme de Terre L. Lake (D, Poor). Both are in Wisconsin.

Both H.S. Truman Res. Nr. Dam Lake and Pomme de Terre L. Lake sit in Missouri. 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 — H.S. Truman Res. Nr. Dam Lake (C) versus Pomme de Terre L. 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.
