Lost Valley Lake vs Peaceful Valley Lake
Water quality, depth, fish species, and recreation comparison.
Lost Valley Lake and Peaceful Valley Lake both received the same overall water quality grade of C (Fair). Both are in Gasconade County, Wisconsin.
Lost Valley Lake and Peaceful Valley Lake are both in Missouri — 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 — Lost Valley Lake (C) versus Peaceful Valley Lake (C). 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.

Side-by-Side Metrics
| Metric | Lost Valley Lake | Peaceful Valley Lake |
|---|---|---|
| Overall Grade | C (Fair) | C (Fair) |
| Water Clarity | 3.9 ft | 4 ft |
| Phosphorus | 22.7 µg/L | 25.7 µg/L |
| Chlorophyll-a (Algae) | 7.2 µg/L | 9.1 µg/L |
| Maximum Depth | - | - |
| Surface Area | 39 acres | 164 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | eutrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Both lakes earn the same Grade C. The tiebreakers come down to clarity (Lost Valley Lake: 3.9 ft, Peaceful Valley Lake: 4 ft) and what you want from the lake. Lost Valley Lake matches its peer on species count.
