Brookfield Lake vs Marceline Lake
Water quality, depth, fish species, and recreation comparison.
Brookfield Lake has a higher water quality grade (B, Good) than Marceline Lake (F, Very Poor). Both are in Linn County, Wisconsin.
Both Brookfield Lake and Marceline 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. Brookfield Lake (B) is materially cleaner than Marceline Lake (F). A gap that wide is unlikely to close in a single year of remediation work; it reflects multi-decade differences in the lakes themselves.
For a recreational visitor, the wider grade gap is decisive — Brookfield Lake is the better water-quality choice. For a researcher, the gap is the interesting part: what is different about the two watersheds, and which of those differences is mutable?
Brookfield Lake
Murky, only visible to about 4.4 ft.
Marceline Lake
Very murky, less than 1.9 ft of visibility.
Side-by-Side Metrics
| Metric | Brookfield Lake | Marceline Lake |
|---|---|---|
| Overall Grade | B (Good) | F (Very Poor) |
| Water Clarity | 4.4 ft | 1.9 ft |
| Phosphorus | 19.7 µg/L | 110.9 µg/L |
| Chlorophyll-a (Algae) | 4.9 µg/L | 25.7 µg/L |
| Maximum Depth | - | - |
| Surface Area | 106 acres | 65 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | mesotrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Brookfield Lake wins on overall water quality with a Grade B versus Marceline Lake's Grade F. Water clarity: 4.4 ft vs 1.9 ft. For fishing diversity, Brookfield Lake also leads with 0 species.
