894-acre lake in Kenora District, Ontario. The lake tops out around 20 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Long Lake draws 898 acres inside 22.9 miles of shoreline — 13 islands included. An index of 5.4 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. End to end it runs roughly 4.7 mi, about 1.6 mi across. The water lies in Kenora District. For a second option, Catastrophe Lake lies 2 mi east.
Come spring, look for walleye tight to the bank in 4 to 15 ft. They move out to 6 to 20 ft in summer and finish the year down in 6 to 20 ft. If you only fish one area, make it Deep basin: a deep basin around 18 ft that scores prime in winter. Best bite is the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.

|---|---|---|---|---|
