Measured from the Michigan DNR inland-lake contour survey.

Deepest mapped contour: 15 ft
Mean depth: 5.3 ft · estimated
Surface area: 19 acres
Estimated volume: 102 acre-ft · 33M gal
Shoreline: 1.1 mi · irregular
Aquatic vegetation: 18% of surface · NDVI estimate
Public access: No public DNR launch identified

Additional depth details3 contours

Contour depths: 0–15 ft
Recorded point soundings: 15 ft

81.7% 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 Depth, area and volume are estimated from the interpolated survey surface — historical reference, not measurement.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 2026-08-21

84 / 100Very GoodData confidence: High

Spring 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.

Included in the index

Component	Rating	Points of weight	Measurement
Natural setting	Excellent	24.2 of 30	81% natural land cover within 150 m of shore (35% forest, 44% wetland; 14% developed)
Geometric wind exposure	Excellent	25.0 of 25	mean fetch 332 m · 100% of sampled water within 500 m of shelter · short fetch in most directions
Watercraft controls	None identified	7.5 of 15	No special watercraft restriction identified in the current DNR source. Motors permitted, subject to general law.

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: Moderate — approximately 18% 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 — 35% forest and 44% 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 Boating Access Sites (2026-08), 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.

Fish you might catch

from active stocking

No recent catch, survey, or stocking data for this lake.

Historically stocked, no recent evidence: Brook Trout (last planted 2010), Rainbow Trout (last planted 2007), Arctic Grayling (last planted 1993) — not shown above.

Compiled from Michigan DNR stockings within the last 10 years. Silhouettes are stylized and scaled to typical adult sizes relative to one another. Presence is not a promise — fishing isn’t a sure thing.

Quick answers

Spring Lake — common questions

How deep is Spring Lake?

The deepest contour on the Michigan DNR bathymetric survey of Spring Lake is 15 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 Spring Lake?

Spring Lake covers about 19 acres in Marquette County, Michigan.

What is the average depth of Spring Lake?

The estimated mean depth of Spring Lake is 5.3 ft, calculated from the survey contours.

Is there public access to Spring Lake?

No public launch for Spring Lake appears in the Michigan DNR access data. That is not the same as the lake being private -- municipal and private ramps are not in that source.
