31 / 100ModestData confidence: High

Lake Scugog has a mixed natural and developed setting, long open-water fetch, substantial nearby higher-volume roads.

Motor & speed rules	Not 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.

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: Moderate — 6% forest and 45% 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.

About these fish → the Fish of Ontario guide

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

Lake Scugog — common questions

How deep is Lake Scugog?

The deepest contour on the Ontario MNRF bathymetric survey of Lake Scugog is 6.1 m (20 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 Lake Scugog?

Lake Scugog covers about 6,679 ha (16,503 acres) in Durham Region, Ontario.

Is there public access to Lake Scugog?

The Ontario MNRF lists 9 fishing access points within 100 m of the shoreline of Lake Scugog: 8 boat launches and 1 shoreline access site. Recorded ownership: 4 privately owned. 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.
