380-acre reservoir near Kōloa. The lake tops out around 50 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 380 acres, worked by 3.4 miles of shoreline. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Littoral water — the productive band under ~15 ft — makes up 51% of this chart, as modeled. Call it 1 mi long by 0.8 mi wide at the broadest reach. Kauai County claims this one. Its nearest charted neighbour, Mauka Reservoir, is 2 mi to the northwest.
Spring largemouth bass on Waita Reservoir hold shallow, usually 2 to 10 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 15 to 35 ft. The chart's best answer is Shallow bay flat — weed flat, 6 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a texas-rigged 10" worm or a deep-diving crankbait.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (6 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (13 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (13 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (23 ft) | Blade bait, Jigging spoon |
When the water first warms, peacock bass (tucunaré) slide up into 2 to 12 ft. By summer they slide out to 3 to 15 ft, and by winter most fish are in 6 to 22 ft. If you only fish one area, make it Main-lake point: a point around 13 ft that scores prime in summer. In summer the feeding windows fall in midday and early morning. Keep a topwater (walking bait) or a jerkbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 12 ft | midday & dawn | Main-lake point (13 ft) | Topwater prop bait, Jerkbait (fire tiger) |
| Summer | 3 to 15 ft | midday & dawn | Main-lake point (13 ft) | Topwater (walking bait), Jerkbait |
| Fall | 3 to 15 ft | midday & dawn | Main-lake point (13 ft) | Jerkbait, Swimbait |
| Winter | 6 to 22 ft | midday | Break off the point (23 ft) | Slow jerkbait, Jig |
Spring channel catfish on Waita Reservoir hold shallow, usually 3 to 12 ft. By summer they slide out to 8 to 25 ft, and by winter most fish are in 20 to 40 ft.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Waihohonu Stream inflow (5 ft) | |
| Summer | 8 to 25 ft | night & dusk | Old creek channel (25 ft) | |
| Fall | 10 to 30 ft | dusk | Old creek channel (25 ft) | |

The chart's best answer is Shallow bay flat — weed flat, 6 ft, prime for spring. Best bite is early morning and the evening. Tie on a small sponge spider (fly) or a micro tube jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (6 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |

| Fall | 6 to 18 ft | midday | Shallow bay flat (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Break off the point (23 ft) | Tiny spoon |
Early season tilapia use the shallows, holding in 1 to 6 ft. Expect a summer slide to 2 to 10 ft, then a winter hold in 5 to 18 ft. Put Shallow bay flat first on the milk run — a weed flat near 6 ft that grades prime for spring. In summer the feeding windows fall in midday and early morning. Tie on a micro-jig near weed edges and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (6 ft) | Tiny jig + bread-ball tip, Small worm under float |
