Survey readout
1000 Islands Lake is mapped to a depth of 45 ft on the Indiana DNR survey and covers about 193 acres in Greene County, Indiana. Coverage is sparse: about 80% 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. Depths come from the Indiana DNR survey of 2018.
Measured from the Indiana DNR lake bathymetry survey.

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 — 81% forest and 5% wetland cover within 150 m of shore
