Paddling

Paddling Index methodology v1.0 · calculated 2026-09-16
80 / 100Very GoodData confidence: Medium

Labelle Lake has a heavily wooded and largely undeveloped setting, generally sheltered geometry, limited nearby major-road exposure.

Natural settingExcellent37.7 of 4388% natural land cover within 150 m of shore (78% forest, 1% wetland; 0% developed)
Geometric wind exposureVery Good27.2 of 36mean fetch 726 m · 9% of sampled water within 500 m of shelter · generally short fetch
Motor & speed rulesNot modelled—Canada publishes vessel motor and speed restrictions as federal legal schedules, not map data, so they are not part of the Ontario index. Check local signage and Transport Canada rules before going out.
Public accessNot listed—No publicly listed MNRF fishing access point within 100 m of this shoreline. Municipal, private and informal launches are not all in this source, so this is not evidence that access is poor — the component is excluded and the remaining weights are renormalized.

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
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 — 78% forest and 1% wetland cover within 150 m of shore
Mapped wildlife habitat
None mapped — Ontario MNRF has not mapped moose, deer or waterfowl habitat within 1 km of this lake. The province maps these areas where it has surveyed, so this is not evidence that wildlife is absent. · Ontario MNRF Wildlife Values Area.

How this index is calculated. The Paddling Index is a relative composite derived from lake geometry and public land-cover, access and road-network 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 for Ontario lakes: natural setting 35%, geometric wind exposure 29%, public access 18%, road isolation 18%. Motor and speed restrictions are not modelled for Ontario, and road traffic is estimated from road class, not measured. Where a component has no data the remaining weights are renormalized and the confidence rating is lowered; below Medium confidence no number is shown. Ontario scores are relative to other Ontario lakes and are not directly comparable with Paddling Index scores on our sister sites, which use different data sources and include a watercraft-rules component. Sources: Ontario MNRF bathymetry outline (0 m contour or survey index polygon), Ontario Land Cover v1.0, Ontario MNRF (Open Government Licence – Ontario) (2020) and Ontario Road Network (Open Government Licence – Ontario); traffic estimated by road class, not measured (2026-09). Conditions change quickly — check current weather and local conditions before going out.
Quick answers

Labelle Lake — common questions

How deep is Labelle Lake?

The deepest contour on the Ontario MNRF bathymetric survey of Labelle Lake is 15.2 m (50 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 Labelle Lake?

Labelle Lake covers about 43 ha (105 acres) in Frontenac County, Ontario.

Is there public access to Labelle Lake?

No fishing access point for Labelle Lake appears in the Ontario MNRF fishing access point list (within 100 m of the shoreline), but Labelle Lake lies inside Frontenac Provincial Park (Ontario Parks), which runs its own facilities and is not covered by that data. Check with the park for launch details.
