Survey readout

Bay Lake, East is mapped to a depth of 46 ft on the Michigan DNR survey and covers about 73 acres in Alger County, Michigan.

Measured from the Michigan DNR inland-lake contour survey.

Deepest sounding: 46 ft
Mean depth: 22.7 ft · estimated
Surface area: 73 acres
Estimated volume: 1,658 acre-ft · 540M gal
Shoreline: 2.66 mi · irregular
Aquatic vegetation: 6% of surface · NDVI estimate
Public access: No public DNR launch identified

Additional depth details6 contours

Contour depths: 0–46 ft
Recorded point soundings: 46 ft

26.8% of the surface sits over water shallower than 10 ft; 64.9% is deeper than 20 ft. Depth, area and volume are estimated from the interpolated survey surface — historical reference, not measurement.

Paddling

Paddling Index methodology v1.0 · calculated 2026-08-21

61 / 100MixedData confidence: Medium

Bay Lake, East has a mixed natural and developed setting, well sheltered geometry, limited 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	Mixed	14.8 of 35	45% natural land cover within 150 m of shore (9% forest, 36% wetland; 14% developed)
Geometric wind exposure	Excellent	25.6 of 29	mean fetch 583 m · 26% 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	Very Good	11.4 of 18	limited nearby major-road exposure · 6 MDOT-classified segments within 1.2 km, peak 885 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: Low — wide enough that wakes disperse over most of the lake
Aquatic vegetation: Low — approximately 6% 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: Moderate — 9% forest and 36% wetland cover within 150 m of shore

Compare Michigan lakes by Paddling Index →

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 Watercraft Control Areas (2026-08), USGS/MRLC NLCD Land Cover (2021), MDOT Annual Average Daily Traffic (2025) and MI DNR bathymetric survey outline (0 ft isobath). Conditions change quickly — check current weather and local conditions before going out.

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.
