Measured from the Michigan DNR inland-lake contour survey.

Deepest sounding: 19 ft
Mean depth: 2.8 ft · estimated
Surface area: 42 acres
Estimated volume: 116 acre-ft · 38M gal
Shoreline: 2.47 mi · irregular
Aquatic vegetation: 58% of surface · NDVI estimate
Public access: No public DNR launch identified

Additional depth details4 contours

Contour depths: 0–19 ft
Recorded point soundings: 19 ft, 15 ft

88.8% of the surface sits over water shallower than 10 ft; the survey shows 2 distinct basins. Depth, area and volume are estimated from the interpolated survey surface — historical reference, not measurement.

76 / 100GoodData confidence: Medium

Little Brush Lake has a mostly natural, lightly 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	Very Good	25.5 of 35	76% natural land cover within 150 m of shore (40% forest, 33% wetland; 19% developed)
Geometric wind exposure	Excellent	29.4 of 29	mean fetch 361 m · 94% 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	12.2 of 18	limited nearby major-road exposure · 9 MDOT-classified segments within 1.2 km, peak 1,085 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: Moderate — narrow in places — wakes would carry across parts of the lake
Aquatic vegetation: High — approximately 58% 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 — 40% forest and 33% 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 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.

Beta. This panel is newly published. Every value is parsed from the Michigan DNR fisheries orders and hand-checked against the printed digest, but the coverage and wording are still under review. If anything here disagrees with the Michigan DNR's Fisheries Orders or its printed digest, the DNR is right — the signed Fisheries Order is the legal text; the digest summarises it.

Notable catches

Master Angler program · 2021

One Master Angler catch is on record for this lake: 14.5″ crappie in 2021 on artificial lure.

Master Angler entries are fish that met the program’s minimum size and were registered by the angler — they show what this lake has produced, not what a day here will produce. A catch on record is history, not a species listing: “Fish you might catch” lists only species with current evidence. Source: Michigan DNR Master Angler data.
