Survey readout

Winslow Lake is mapped to a depth of 25 ft on the Michigan DNR survey and covers about 258 acres in Iron 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).

Deepest mapped contour: 25 ft
Mean depth: 8.9 ft · estimated
Surface area: 258 acres
Estimated volume: 2,301 acre-ft · 750M gal
Shoreline: 4.97 mi · irregular
Aquatic vegetation: 11% of surface · NDVI estimate
Public access: Boat Launch

Additional depth details5 contours

Contour depths: 0–25 ft
Recorded point soundings: 25 ft

58.8% of the surface sits over water shallower than 10 ft; 5.2% 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 Depth, area and volume are estimated from the interpolated survey surface — historical reference, not measurement.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

68 / 100MixedData confidence: Medium

Winslow Lake has a heavily wooded and largely undeveloped setting, generally 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	Excellent	29.2 of 35	81% natural land cover within 150 m of shore (41% forest, 40% wetland; 8% developed)
Geometric wind exposure	Very Good	16.7 of 29	mean fetch 1,154 m · 5% of sampled water within 500 m of shelter · generally short fetch
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	13.0 of 18	limited nearby major-road exposure · 4 MDOT-classified segments within 1.2 km, peak 117 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 11% 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 — 41% forest and 40% 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.

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 · 2004–2017

Master Angler catches recorded on this lake — too few to show a pattern, so they are listed individually.

Bluegill11.5″ · 2017 · ice fishing

Bluegill10.2″ · 2004 · spincasting · worm

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.

Stocking: Fishery Resource History The earliest records of fisheries management in Winslow Lake occurred in 1934 with stocking of Walleye fry, followed by additional stockings of Walleye, Largemouth Bass, and Bluegill in 1937, and Walleye again in 1938 and 1939.

This survey reported catch counts without lengths. Source: Michigan DNR Status of the Fishery Resource report.
