Paddling
Paddling Index methodology v1.0 · calculated 2026-08-21Mona Lake has a substantially developed setting, moderate open-water exposure, substantial nearby higher-volume roads. Watercraft controls: Slow-no-wake zones.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Modest | 0.6 of 30 | 11% natural land cover within 150 m of shore (4% forest, 6% wetland; 81% developed) |
| Geometric wind exposure | Good | 13.2 of 25 | mean fetch 1,270 m · 3% of sampled water within 500 m of shelter · moderate open-water fetch |
| Watercraft controls | Slow-no-wake zones | 10.2 of 15 | Slow — no wake — designated zones only |
| Public access | Good | 12.8 of 15 | 1 site with DNR boating-facility records · 2 ramp lanes · 41 trailer spaces |
| Road isolation | Modest | 0.8 of 15 | substantial nearby higher-volume roads · 508 MDOT-classified segments within 1.2 km, peak 48,308 vehicles/day |
Additional paddling considerations
These describe the lake but are not part of the v1 Paddling Index and do not change the number above.
- Wake sensitivity
- Low — wide enough that wakes disperse over most of the lake
- Aquatic vegetation
- Low — approximately 1% mapped coverage · NAIP aerial imagery (NDVI)
- Observed motorized activity
- Unknown — No lake-level measurement of boat traffic is available. Legal permission to operate motors is not evidence of use.
- Wildlife habitat potential
- Limited — 4% forest and 6% wetland cover within 150 m of shore

What does non-native mean?
USGS records identify non-native species that have been documented for this lake or its shoreline. Non-native does not necessarily mean invasive, and historical records do not confirm current presence.
