Included in the index

ComponentRatingPoints of weightMeasurement
Natural settingExcellent39.5 of 4393% natural land cover within 150 m of shore (91% forest, 0% wetland; 3% developed)
Geometric wind exposureMixed8.2 of 36mean fetch 2,590 m · 0% of sampled water within 500 m of shelter · long fetch in some directions
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.
Road isolationExcellent19.1 of 21relatively isolated from major roads · 2 Ontario Road Network segments within 1.2 km (traffic estimated from road class, not measured)

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 — 91% forest and 0% 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. 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).

Quick answers

Little Chiblow Lake — common questions

How deep is Little Chiblow Lake?

The deepest contour on the Ontario MNRF bathymetric survey of Little Chiblow Lake is 36.6 m (120 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 Little Chiblow Lake?

Little Chiblow Lake covers about 654 ha (1,616 acres) in Algoma District, Ontario.

Is there public access to Little Chiblow Lake?

No fishing access point for Little Chiblow 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.

Do First Nation rules apply on Little Chiblow Lake?

Little Chiblow Lake has 42% of its shoreline in Mississagi River 8, a First Nation reserve. Fishing, boating and access on reserve land and waters can be governed by the First Nation's own rules as well as Ontario's. Check with the First Nation before fishing or launching.
