Paddling
Paddling Index methodology v1.0 · calculated 2026-09-16Rice Lake has a mixed natural and developed setting, long open-water fetch, substantial nearby higher-volume roads.
Why this score?5 components
Included in the index
| Component | Rating | Points of weight | Measurement |
|---|---|---|---|
| Natural setting | Mixed | 14.1 of 35 | 54% natural land cover within 150 m of shore (15% forest, 33% wetland; 30% developed) |
| Geometric wind exposure | Modest | 1.5 of 29 | mean fetch 12,641 m · 0% of sampled water within 500 m of shelter · long open-water fetch |
| 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. |
| Public access | Good | 15.0 of 18 | 9 MNRF fishing access points · boat ramp · ADA-accessible |
| Road isolation | Modest | 0.9 of 18 | substantial nearby higher-volume roads · 3407 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
- Moderate — 15% forest and 33% wetland cover within 150 m of shore
- Mapped wildlife habitat
- None mapped — Ontario MNRF has not mapped moose, deer or waterfowl habitat within 1 km of this lake. The province maps these areas where it has surveyed, so this is not evidence that wildlife is absent. · Ontario MNRF Wildlife Values Area.

Rice Lake — common questions
How deep is Rice Lake?
The deepest contour on the Ontario MNRF bathymetric survey of Rice Lake is 11 m (36 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 Rice Lake?
Rice Lake covers about 10,021 ha (24,762 acres) in Peterborough County, Ontario.
Is there public access to Rice Lake?
The Ontario MNRF lists 9 fishing access points within 100 m of the shoreline of Rice Lake: 9 boat launches. Recorded ownership: 2 municipal, 1 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. Check locally before you go.
Do First Nation rules apply on Rice Lake?
Rice Lake has 4% of its shoreline in Hiawatha First Nation 36, 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.
