There is an exit to Whonnock Creek on the south-east side originally closed off by a sandbar (beaver dam) that was replaced in 2008 by a man-made berm and fish channel.

In the past beavers regulated the water level of the lake — now the city does that.

Whonnock Lake is a rural-residential neighbourhood in eastern Maple Ridge, British Columbia, Canada, located about 40 miles (64 km) east of Vancouver in the upland area of Whonnock south of the Dewdney Trunk Road.
