5-acre lake in Maricopa County, Arizona. The lake tops out around 12 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 4 acres wrapped in 0.3 miles of bank. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. Maricopa County claims this one. Its nearest charted neighbour, Desert West Lake, is 7 mi to the south.
Early season rainbow trout use the shallows, holding in 3 to 12 ft. Even in summer they hold at 3 to 12 ft; winter keeps them in 2 to 12 ft. The chart's best answer is Shoreline break — drop-off, 5 ft, prime for winter. Best bite is early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Shoreline break (5 ft) | Inline spinner (silver), Small spoon |
| Summer | 3 to 12 ft | dawn & dusk | Shoreline break (5 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 3 to 12 ft | dawn & dusk | Shoreline break (5 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 2 to 12 ft | dawn | Shoreline break (5 ft) | Jigging spoon, Tube jig (white) |
When the water first warms, largemouth bass slide up into 2 to 10 ft. By summer they slide out to 4 to 12 ft, and by winter most fish are in 4 to 12 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a texas-rigged 10" worm or a deep-diving crankbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 4 to 12 ft | dawn & dusk | Shoreline break (5 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Squarebill crankbait (shad), Spinnerbait |

When the water first warms, channel catfish slide up into 3 to 12 ft. There's no big seasonal slide here — summer means 4 to 12 ft, winter 4 to 12 ft. If you only fish one area, make it Deep basin: a deep basin around 10 ft that scores prime in winter. In summer the feeding windows fall in after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (3 ft) | |
| Summer | 4 to 12 ft | night & dusk | Deep basin (10 ft) | |
| Fall | 4 to 12 ft | dusk | Deep basin (10 ft) | |
| Winter | 4 to 12 ft | midday | Deep basin (10 ft) |
When the water first warms, bluegill slide up into 1 to 6 ft. Summer is a 3 to 12 ft game here, winter a 4 to 12 ft one. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a small sponge spider (fly) or a micro tube jig rigged through the warm months.
| 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) |
| Summer | 3 to 12 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 4 to 12 ft | midday | Shoreline break (5 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 4 to 12 ft | midday | Deep basin (10 ft) | Tiny spoon |
Structure-wise the chart holds 3 features, led in depth by Deep basin at roughly 10 ft.
