Paddling

Paddling Index methodology v1.0 · calculated 2026-09-16
86 / 100Very GoodData confidence: High

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

On a canoe route · portages mapped. Portage trails end at this shoreline. Portages carry canoes over land between waters, and the ground around the lake in the 3D view is terrain those trails cross. Trail condition, length and elevation change are not measured here — check the park or canoe-route map before you go. Trails: OpenStreetMap (ODbL).

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 — 93% forest and 2% wetland cover within 150 m of shore
Mapped wildlife habitat
Mapped — Ontario MNRF has mapped moose aquatic feeding area, moose wintering area and waterfowl staging or nursery areas within 1 km of this lake. These are habitat records from provincial surveys, not animal counts; areas with nothing mapped may still hold wildlife. · 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.

Quick answers

Cinder Lake — common questions

How deep is Cinder Lake?

The deepest contour on the Ontario MNRF bathymetric survey of Cinder Lake is 34 m (112 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 Cinder Lake?

Cinder Lake covers about 102 ha (253 acres) in Haliburton County, Ontario.

Is there public access to Cinder Lake?

The Ontario MNRF lists 2 fishing access points within 100 m of the shoreline of Cinder Lake: 1 boat launch and 1 shoreline access site. Recorded ownership: 1 municipal. The list includes municipal and privately owned sites, and some may charge a fee or restrict parking, so it confirms a place anglers use rather than a public right of way. Check locally before you go.
