Survey readout
Algonquin Lake is mapped to a depth of 45 ft on the Michigan DNR survey and covers about 242 acres in Barry County, Michigan.
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: Carter Lake. Their launches are not marked on the model — only Algonquin Lake’s own are.
61.4% of the surface sits over water shallower than 10 ft; 20.5% is deeper than 20 ft; the survey shows 2 distinct basins. Depth, area and volume are estimated from the interpolated survey surface — historical reference, not measurement.

Paddling
Paddling Index methodology v1.0 · calculated 2026-08-21Algonquin Lake has a substantially developed setting, generally sheltered geometry, substantial nearby higher-volume roads. No special watercraft restriction is identified in the current source.

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
- Low — approximately 8% 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 — 21% forest and 8% wetland cover within 150 m of shore

What does non-native mean?
USGS records identify non-native species that have been documented for this lake or its shoreline. Non-native does not necessarily mean invasive, and historical records do not confirm current presence.
