178-acre lake in Frontenac County, Ontario. The lake tops out around 17 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. The season-by-season read for each species follows, from the map's own numbers.
On the chart, Buck Lake draws 177 acres inside 4.1 miles of shoreline. An index of 2.2 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 92% of this chart, as modeled. End to end it runs roughly 1.2 mi, about 0.5 mi across. You'll find it in Frontenac County. For a second option, Bull Lake lies 2 mi southwest.
Early season walleye use the shallows, holding in 4 to 15 ft. Expect a summer slide to 5 to 17 ft, then a winter hold in 5 to 17 ft. Put Break off the point first on the milk run — a drop-off near 8 ft that grades prime for fall. In summer the feeding windows fall in the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.

|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 5 to 17 ft | dusk & dawn | Break off the point (8 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 5 to 17 ft | dusk & night | Break off the point (8 ft) | Jigging rap, Jig + big minnow |
| Winter | 5 to 17 ft | dusk & dawn | Deep basin (14 ft) | Jigging spoon + minnow head, Rattle bait |
Spring yellow perch on Buck Lake hold shallow, usually 3 to 12 ft. They move out to 5 to 17 ft in summer and finish the year down in 5 to 17 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.

Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 5 to 17 ft; cold water stacks them in 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.

The spot to know is Break off the point, a drop-off in about 8 ft of water that rates prime for muskellunge in fall. Plan around the evening and early morning in the warm months. Summer baits: a double-10 bucktail or a topwater (walk-the-dog / creeper) gets it done.

A drop shot (goby/minnow) or a ned rig covers the summer program.
