Paddling

Paddling Index methodology v1.0 · calculated 2026-09-21
90 / 100ExcellentData confidence: High

Olinger Lake has a heavily wooded and largely undeveloped setting, well sheltered geometry, limited nearby major-road exposure. Watercraft controls: Electric motors only.

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
Moderate — narrow in places — wakes would carry across parts of the lake
Aquatic vegetation
Low — approximately 7% 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 — 93% forest and 2% wetland cover within 150 m of shore
How this index is calculated. The Paddling Index is a relative composite derived from lake geometry and public environmental, access, roadway and watercraft-control data. It is not a user review, a safety rating, or a prediction of an individual outing. Differences of a few points should not be treated as meaningful — an 84 and an 82 are broadly comparable. Components and weights: natural setting 30%, geometric wind exposure 25%, watercraft controls 15%, public access 15%, road isolation 15%; observed motorboat activity is weighted 0% because no defensible lake-level measurement exists. Where a component has no data the remaining weights are renormalized and the confidence rating is lowered; below Medium confidence no number is shown.

Quick answers

Olinger Lake — common questions

How deep is Olinger Lake?

The deepest contour on the Indiana DNR bathymetric survey of Olinger Lake is 21 ft. That is the deepest depth the historical survey map records, which may differ from the deepest point of the lake itself.

How big is Olinger Lake?

Olinger Lake covers about 18 acres in Orange County, Indiana.

Is there public access to Olinger Lake?

Yes, from shore. The Indiana DNR lists a public access site on Olinger Lake: a shoreline fishing site. The DNR notes that an entry fee applies. DNR directions: "Off of SR 145, approximately 0.37 mile N of the junction of SR 145 and CR 875."
