Fishing Jackfish Lake: what the data says

2,572-acre lake in Rainy River District, Ontario. The lake tops out around 60 ft. The depth data here comes from the Ontario MNRF survey of 1970, a decades-old survey (a transect sounding survey). The exact depth survey is published on its own because no defensible water-specific species roster was found.

Traced from the shoreline, Jackfish Lake runs 2,584 acres with 51 miles of edge, with 36 islands in the mix. A development index of 7.2 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 45% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 4.4 mi, about 3.1 mi across. The water lies in Rainy River District. The nearest mapped water is Footprint Lake, 3 mi to the south.
