Other waters with a public launch on this map: Lake Huron, Thunder Bay River. Their launches are not marked on the model — only Ninth Street Pond’s own are.
96.9% of the surface sits over water shallower than 10 ft. Depth, area and volume are estimated from the interpolated survey surface — historical reference, not measurement.

Paddling
Paddling Index methodology v1.0 · calculated 2026-08-21Ninth Street Pond has a substantially developed setting, moderate open-water exposure, substantial nearby higher-volume roads. No special watercraft restriction is identified in the current source.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Modest | 0.7 of 35 | 12% natural land cover within 150 m of shore (4% forest, 6% wetland; 76% developed) |
| Geometric wind exposure | Good | 15.0 of 29 | mean fetch 1,317 m · 3% of sampled water within 500 m of shelter · moderate open-water fetch |
| Watercraft controls | None identified | 8.8 of 18 | No special watercraft restriction identified in the current DNR source. Motors permitted, subject to general law. |
| Public access | Not listed | — | No DNR-listed access site. Township, county and road-end launches are not in this source, so this is not evidence that access is poor — the component is excluded and the remaining weights are renormalized. |
| Road isolation | Modest | 0.9 of 18 | substantial nearby higher-volume roads · 275 MDOT-classified segments within 1.2 km, peak 17,191 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
- High — approximately 57% 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
