12-acre reservoir near Lahaina. The lake tops out around 25 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, Crater Reservoir draws 11 acres inside 0.7 miles of shoreline. A shoreline index of 1.4 says round and simple: fish relate to depth changes here, not shoreline features. Roughly 48% of the water is 15 ft or less as modeled, the band where the food chain lives. Figure 0.3 mi of water from one end to the other. You'll find it in Maui County. Closest neighbour on DepthScout: Waiale Reservoir, 11 mi east of here.
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 8 to 25 ft for winter. The spot to know is Main-lake point, a point in about 8 ft of water that rates prime for largemouth bass in fall. Plan around early morning and the evening in the warm months. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Main-lake point (8 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (11 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 | 8 to 25 ft | midday | Break off the point (11 ft) | Blade bait, Jigging spoon |
In spring, bluegill run shallow here, mostly 1 to 6 ft. Midsummer fish sit out in 4 to 15 ft before dropping to 10 to 25 ft for winter. Winter bluegill concentrate at Deep basin, a prime-rated deep basin around 21 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small sponge spider (fly) or a micro tube jig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | open water | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | open water | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Break off the point (11 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (21 ft) | Tiny spoon |
Start shallow in spring: tilapia sit in 1 to 6 ft that time of year. Warm water sends them out to 2 to 10 ft; cold water stacks them in 5 to 18 ft. Top water on the chart: Break off the point, a drop-off in the 11 ft range, prime in winter. Fish it in midday and early morning and you'll meet the bite. Throw a micro-jig near weed edges until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Main-lake point (8 ft) | Tiny jig + bread-ball tip, Small worm under float |
| Summer | 2 to 10 ft | midday & dawn | open water | Micro-jig near weed edges |
| Fall | 3 to 12 ft | midday | Break off the point (11 ft) | Small jig tipped with worm |
| Winter | 5 to 18 ft | midday | Break off the point (11 ft) | Slow micro-jig, warm outflows |
