183-acre lake in Muskoka District Municipality, Ontario. The lake tops out around 85 ft. The depth data here comes from the Ontario MNRF survey of 2010 (an MNRF lake survey). Below is the species-by-species picture, pulled from the same data the map uses.
Spring cisco (lake herring) on Grandview Lake hold shallow, usually 10 to 40 ft. They move out to 40 to 80 ft in summer and finish the year down in 20 to 60 ft.
