13-acre reservoir near Kīlauea. The lake tops out around 25 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 13 acres wrapped in 0.8 miles of bank. A middling shoreline index (1.7) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 41% of this chart, as modeled. Kauai County claims this one. If the bite dies, Puu Ka Ele Reservoir is 2 mi to the southwest.
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 8 to 25 ft. Put Main-lake point first on the milk run — a point near 8 ft that grades prime for fall. In summer the feeding windows fall in early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
| 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 |
Come spring, look for peacock bass (tucunaré) tight to the bank in 2 to 12 ft. Expect a summer slide to 3 to 15 ft, then a winter hold in 6 to 22 ft. Start at Main-lake point. It's a point holding about 8 ft of water and rates prime come spring. Prime time lands in midday and early morning. A topwater (walking bait) or a jerkbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 12 ft | midday & dawn | Main-lake point (8 ft) | Topwater prop bait, Jerkbait (fire tiger) |
| Summer | 3 to 15 ft | midday & dawn | Main-lake point (8 ft) | Topwater (walking bait), Jerkbait |
| Fall | 3 to 15 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Swimbait |
| Winter | 6 to 22 ft | midday | Break off the point (11 ft) | Slow jerkbait, Jig |
Spring bluegill on Waiakalua Reservoir hold shallow, usually 1 to 6 ft. They move out to 4 to 15 ft in summer and finish the year down in 10 to 25 ft. Put Deep basin first on the milk run — a deep basin near 21 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a small sponge spider (fly) or a micro tube jig.
| 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 |
Spring tilapia on Waiakalua Reservoir hold shallow, usually 1 to 6 ft. By summer they slide out to 2 to 10 ft, and by winter most fish are in 5 to 18 ft. The chart's best answer is Break off the point — drop-off, 11 ft, prime for winter. Prime time lands in midday and early morning. The summer box starts with a micro-jig near weed edges.
| 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 |
Structure-wise the chart holds 3 features, led in depth by Deep basin at roughly 21 ft.
