Paddling

60 / 100MixedData confidence: Medium

Brule Lake has a partly natural setting, generally sheltered geometry, limited nearby major-road exposure. 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
Low — wide enough that wakes disperse over most of the lake
Aquatic vegetation
Moderate — approximately 16% 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 — 43% forest and 20% 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).

Fishing rules for this lake Beta

Size and daily limits for the 2 species found here — 2 open to harvest.

These are hook-and-line size, daily limit and season rules. Gear, spearing and bow fishing, spawning closures and rod limits are set by other Fisheries Orders and are not shown here.

BluegillOpen to harvestMinimum size: no size limit · Daily limit: 25 (FO-215 · statewide inland) The 25 is in any combination of the sunfishes — Bluegill, Pumpkinseed, Black and White Crappie, Rock Bass, Green, Longear and Redear Sunfish, Warmouth and hybrids — not 25 of each (FO-215.23A).

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 · 2007–2025

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

Bluegill10″ · 2025 · spincasting · live bait
Bluegill10″ · 2025 · spincasting · live bait
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.

DNR stocking

state stocking record · 1980–1993

Fish the Michigan DNR has planted in this lake — what was added, distinct from what a survey netted above.

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.
