Fishing French River: what the data says

497-acre lake in Sudbury District, Ontario. The lake tops out around 53 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. The exact depth survey is published on its own because no defensible water-specific species roster was found.

On the chart, French River draws 500 acres inside 21.4 miles of shoreline, broken up by 30 islands. A development index of 6.8 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 50% of the water is 15 ft or less, the band where the food chain lives. Call it 3.7 mi long by 1 mi wide at the broadest reach. The water lies in Sudbury District. For a second option, Eastern Outlet (French River) lies 1 mi southeast.
