Lake Nipissing

Lake Nipissing is a lake in the Canadian province of Ontario. It has a surface area of 873.3 km2, a mean elevation of 196 m above sea level, and is located between the Ottawa River and Georgian Bay. Lake Nipissing is the third-largest lake entirely in Ontario. It is relatively shallow for a large lake, with an average depth of only 4.5 m. The shallowness of the lake makes for many sandbars along the lake's irregular shoreline. The lake reaches a maximum depth of 64 m near the mouth of the French River, off the shore of Blueberry Island. The lake has many islands most of which are protected under the Protection of Significant Wetlands scheme, controlled by the Ministry of Natural Resources and Forestry.

The largest population centre on the lake's shoreline is the city of North Bay. North Bay sits along the lake's northeastern shoreline. Other notable towns include Callander. The larger towns toward the western end of the lake are Sturgeon Falls, Garden Village, Cache Bay and Lavigne.
