56-acre lake in Renfrew County, Ontario. The lake tops out around 7 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. The season-by-season read for each species follows, from the map's own numbers.
The outline encloses 56 acres, worked by 1.6 miles of shoreline. A middling shoreline index (1.6) gives it some bays to work without being a maze. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. End to end it runs roughly 0.6 mi, about 0.3 mi across. It sits in Renfrew County. If the bite dies, Dicks Lake is 1 mi to the southwest.
