Paddling

Paddling Index methodology v1.0 · calculated 2026-09-16
91 / 100ExcellentData confidence: High

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

On a canoe route · portages mapped. Portage trails end at this shoreline, including Norway to Bear Lake Portage. 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
Moderate — narrow in places — wakes would carry across parts 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 — 68% forest and 21% wetland cover within 150 m of shore
Mapped wildlife habitat
Mapped — Ontario MNRF has mapped deer wintering 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

Norway Lake — common questions

How deep is Norway Lake?

The deepest contour on the Ontario MNRF bathymetric survey of Norway Lake is 12.2 m (40 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 Norway Lake?

Norway Lake covers about 38 ha (94 acres) in Lennox and Addington County, Ontario.

Is there public access to Norway Lake?

The Ontario MNRF lists 1 fishing access point within 100 m of the shoreline of Norway Lake: 1 boat launch. 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.
