Paddling

Paddling Index methodology v1.0 · calculated 2026-08-21
78 / 100GoodData confidence: High

Alderman Lake has a heavily wooded and largely undeveloped setting, well sheltered geometry, 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
High — narrow throughout — passing wakes would reach most of the water
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 — 21% forest and 72% 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.

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.

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.
