334-acre lake in Leeds and Grenville United Counties, Ontario. The lake tops out around 15 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 339 acres, worked by 9.6 miles of shoreline, broken up by 4 islands. An index of 3.7 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. End to end it runs roughly 2 mi, about 0.7 mi across. Leeds and Grenville United Counties claims this one. Its nearest charted neighbour, Graham Lake, is 1 mi to the south.
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 5 to 15 ft, and winter fish settle into 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
