731-acre lake in Leeds and Grenville United Counties, Ontario. The lake tops out around 15 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Graham Lake draws 733 acres inside 9.4 miles of shoreline — one island included. A development index of 2.5 means a maze of bays and points: far more casting targets than a round bowl of the same size. End to end it runs roughly 3.8 mi, about 0.5 mi across. You'll find it in Leeds and Grenville United Counties. For a second option, Temperance Lake lies 1 mi north.
Spring yellow perch on Graham Lake hold shallow, usually 3 to 12 ft. They move out to 5 to 15 ft in summer and finish the year down in 5 to 15 ft. Put Deep basin first on the milk run — a deep basin near 13 ft that grades prime for fall. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.

|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |

Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 5 to 15 ft; cold water stacks them in 5 to 15 ft. Break off the point is the standout, a drop-off at roughly 5 ft, rated prime for fall 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.
