Rating depth structure for largemouth bass.
Recent public catches load as you reach this section.
23-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 rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Brady Lake runs 23 acres with 1.4 miles of edge. The shoreline is moderately structured (index 2.1) — enough points and pockets to pattern. 67% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. The basin spans about 0.6 mi end to end. You'll find it in Frontenac County. The nearest mapped water is Loon Lake, 2 mi to the east.
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Warm water sends them out to 5 to 17 ft; cold water stacks them in 5 to 17 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 5 to 17 ft | dawn & dusk | Break off the point (8 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 17 ft | midday | Break off the point (8 ft) | Blade bait, Jigging spoon |
Spring rock bass on Brady Lake hold shallow, usually 2 to 10 ft. They move out to 4 to 17 ft in summer and finish the year down in 5 to 17 ft.

Spring puts bluegill in skinny water — 1 to 6 ft is the zone. Warm water sends them out to 4 to 15 ft; cold water stacks them in 5 to 17 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring bluegill. Plan around early morning and the evening in the warm months. A small sponge spider (fly) or a micro tube jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |

The summer box starts with a micro tube or a sponge spider (fly).
