925-acre lake in Cochrane District, Ontario. The lake tops out around 20 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Every species below gets its seasonal read from the same numbers driving the chart.
Obobka Lake maps at 929 acres behind 17.2 miles of shoreline, with 25 islands in the mix. An index of 4 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 87% of this chart. End to end it runs roughly 3.8 mi, about 1 mi across. Cochrane District claims this one. Truax Lake sits 4 mi southwest — the closest neighbouring chart.
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Summer pushes them deeper, 6 to 20 ft, and winter fish settle into 6 to 20 ft. The spot to know is Break off the point, a drop-off in about 19 ft of water that rates prime for walleye in fall. Warm-month bites cluster around the evening and early morning. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
