Paddling

Paddling Index methodology v1.0 · calculated 2026-09-16
64 / 100MixedData confidence: Medium

Paradise Lake has a heavily wooded and largely undeveloped setting, notable open-water exposure, limited nearby major-road exposure.

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 — 87% forest and 6% wetland cover within 150 m of shore
Mapped wildlife habitat
Mapped — Ontario MNRF has mapped moose aquatic feeding areas and moose 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. 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.

Angler catch reports

Fish ON-Line · 2016

One angler has logged a trip here: 8 smallmouth bass and 1 lake trout, fished from shore, in July 2016.

Pictures are sized relative to each other. Illustrations are AI-generated representative adults in everyday colours, not photographs (provenance).

This is a single angler’s report — a snapshot of one trip, not a picture of the whole lake.

Trips are logged voluntarily by anglers in Ontario’s Fish ON-Line app. This is what people report catching, not a Ministry survey, and a species nobody has logged may still be here.

A logged catch does not mean it is legal to catch or keep: check the Ontario Fishing Regulations Summary for this lake’s zone and exceptions.
Quick answers

Paradise Lake — common questions

How deep is Paradise Lake?

The deepest contour on the Ontario MNRF bathymetric survey of Paradise Lake is 32 m (105 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 Paradise Lake?

Paradise Lake covers about 504 ha (1,244 acres) in Sudbury District, Ontario.

Is there public access to Paradise Lake?

No fishing access point for Paradise Lake appears in the Ontario MNRF fishing access point list (within 100 m of the shoreline). That is not the same as the lake being private -- the MNRF list is incomplete, and many municipal, marina and private launches are not in it.
