Survey readout
Martiny Lake is mapped to a depth of 40 ft on the Michigan DNR survey and covers about 2,082 acres in Mecosta County, Michigan. Coverage is sparse: about 58% of this lake lies well away from any surveyed contour, so most of the shape shown there is interpolated between distant measurements rather than mapped.
Measured from the Michigan DNR inland-lake contour survey (depths read from the survey's isobath field; this lake's summary-depth column is blank in the source).

Other waters with a public launch on this map: Pretty Lake, Jehnsen Lake. Their launches are not marked on the model — only Martiny Lake’s own are.
81.5% of the surface sits over water shallower than 10 ft; 13.2% is deeper than 20 ft; the survey shows 3 distinct basins. Depth, area and volume are estimated from the interpolated survey surface — historical reference, not measurement.

Paddling
Paddling Index methodology v1.0 · calculated 2026-08-21Martiny Lake has a mostly natural, lightly developed setting, notable open-water exposure, nearby higher-volume roads. No special watercraft restriction is identified in the current source.
Why this score?5 components

|---|---|---|---|
| Natural setting | Very Good | 21.1 of 30 | 76% natural land cover within 150 m of shore (26% forest, 48% wetland; 22% developed) |
| Geometric wind exposure | Mixed | 5.8 of 25 | mean fetch 2,608 m · 3% of sampled water within 500 m of shelter · long fetch in some directions |
| Watercraft controls | None identified | 7.5 of 15 | No special watercraft restriction identified in the current DNR source. Motors permitted, subject to general law. |
| Public access | Good | 12.8 of 15 | 3 sites with DNR boating-facility records · 3 ramp lanes · 44 trailer spaces |

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 64% 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
- High — 26% forest and 48% wetland cover within 150 m of shore
