Additional depth details2 contours

Contour depths: 0–10 ft
Recorded point soundings: 10 ft

96.7% 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 Depth, area and volume are estimated from the interpolated survey surface — historical reference, not measurement.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 2026-09-23

90 / 100ExcellentData confidence: Medium

Hankard Lake has a heavily wooded and largely undeveloped setting, well sheltered geometry, little nearby major-road exposure. 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	Excellent	35.3 of 35	99% natural land cover within 150 m of shore (19% forest, 80% wetland; 0% developed)
Geometric wind exposure	Excellent	29.4 of 29	mean fetch 223 m · 100% of sampled water within 500 m of shelter · short fetch in most directions
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	Excellent	16.4 of 18	relatively isolated from major roads · 3 MDOT-classified segments within 1.2 km, peak 196 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: High — narrow throughout — passing wakes would reach most of the water
Aquatic vegetation: High — approximately 51% 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 — 19% forest and 80% 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. Sources: MI DNR bathymetric survey outline (0 ft isobath), USGS/MRLC NLCD Land Cover (2021), MI DNR Watercraft Control Areas (2026-08) and MDOT Annual Average Daily Traffic (2025).

Quick answers

Hankard Lake — common questions

How deep is Hankard Lake?

What is the average depth of Hankard Lake?

The estimated mean depth of Hankard Lake is 4.8 ft, calculated from the survey contours.

Is there public access to Hankard Lake?

No public launch for Hankard Lake appears in the Michigan DNR access data, but Hankard Lake lies inside Waterloo Recreation Area (Michigan DNR), which runs its own facilities and is not covered by that data. Check with the park for launch details.
