122-acre lake near Custer. The lake tops out around 138 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.
Traced from the shoreline, Toxaway Lake runs 124 acres with 3.2 miles of edge, with a single island in the mix. Index 2 on the shoreline: a few honest points and pockets, nothing labyrinthine. Roughly 28% of the water is 15 ft or less as modeled, the band where the food chain lives. The basin spans about 0.9 mi end to end and 0.4 mi across at its widest. The water lies in Custer County. The nearest mapped water is Pettit Lake, 5 mi to the east.
Start shallow in spring: rainbow trout sit in 5 to 20 ft that time of year. Warm water sends them out to 8 to 30 ft; cold water stacks them in 8 to 40 ft. Top water on the chart: Main-lake point, a point in the 35 ft range, prime in fall. Fish it in early morning and the evening and you'll meet the bite. Throw a dodger + spoon (deep troll) or a flutter spoon until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Shallow bay flat (6 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (35 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (62 ft) | Jigging spoon, Tube jig (white) |
