19-acre lake in Cochrane District, Ontario. The lake tops out around 50 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Here is how the season plays out for each species, straight from the data behind the map.
The drawn water covers 19 acres wrapped in 1.1 miles of bank. With a 1.8 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 44% of the surface on the model — that's where the groceries are. End to end it runs roughly 0.5 mi. Cochrane District claims this one. Pintail Lake sits 1 mi northwest — the closest neighbouring chart.
Spring brook trout on Bittern Lake hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Break off the point first on the milk run — a drop-off near 23 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
