265-acre reservoir near Nogales. The lake tops out around 70 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Species by species, here's what the data says the year looks like.
Patagonia Lake's chart carries 6.9 miles of bank — one island included. A development index of 3.6 means a maze of bays and points: far more casting targets than a round bowl of the same size. 65% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 1.5 mi, about 0.6 mi across. It sits in Santa Cruz County. If the bite dies, Peña Blanca Lake is 15 mi to the southwest.
When the water first warms, rainbow trout slide up into 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 8 to 40 ft. If you only fish one area, make it Creek inflow: an inflow / creek mouth around 7 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a dodger + spoon (deep troll) or a flutter spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Creek inflow (7 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Creek inflow (7 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (18 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Old creek channel (35 ft) | Jigging spoon, Tube jig (white) |
Spring largemouth bass on Patagonia Lake hold shallow, usually 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 6 ft that grades prime for spring. The feeding windows run 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 (18 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (6 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Old creek channel (35 ft) | Blade bait, Jigging spoon |
Spring channel catfish on Patagonia Lake hold shallow, usually 3 to 12 ft. They move out to 8 to 25 ft in summer and finish the year down in 20 to 40 ft. Put Creek inflow first on the milk run — an inflow / creek mouth near 7 ft that grades prime for spring. The feeding windows run after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Creek inflow (7 ft) | |
| Summer | 8 to 25 ft | night & dusk | Creek inflow (7 ft) | |
| Fall | 10 to 30 ft | dusk | Old creek channel (35 ft) | |
| Winter | 20 to 40 ft | midday | Old creek channel (35 ft) |
Spring flathead catfish on Patagonia Lake hold shallow, usually 5 to 20 ft. By summer they slide out to 8 to 30 ft, and by winter most fish are in 20 to 45 ft. The chart's best answer is Old creek channel — creek channel, 35 ft, prime for fall. Prime time lands in after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | night & dusk | Creek inflow (7 ft) | |
| Summer | 8 to 30 ft | night & dusk | Old creek channel (35 ft) | |
| Fall | 10 to 35 ft | night & dusk | Old creek channel (35 ft) | |
| Winter | 20 to 45 ft | midday | Old creek channel (35 ft) |
Early season crappie use the shallows, holding in 2 to 8 ft. Summer is a 10 to 25 ft game here, winter a 15 to 35 ft one. The chart's best answer is Old creek channel — creek channel, 35 ft, prime for winter. Best bite is early morning and the evening. Tie on a jig trolled/spider-rigged or a small crankbait (trolled) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Shallow bay flat (6 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Shallow bay flat (6 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 15 to 35 ft | midday | Old creek channel (35 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Early season bluegill use the shallows, holding in 1 to 6 ft. Expect a summer slide to 4 to 15 ft, then a winter hold in 10 to 25 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 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) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow bay flat (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Shallow bay flat (6 ft) | Tiny spoon |
Patagonia Lake also holds common carp (3 to 15 ft in summer), green sunfish (2 to 12 ft in summer), redear sunfish (4 to 18 ft in summer). Pick any of them on the map above for rated spots and bait picks.
Count 8 structure marks on this chart. The deepest, Deep basin, sits near 60 ft.

Patagonia Lake is about 70 ft (21 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target rainbow trout, largemouth bass, channel catfish, flathead catfish, crappie, bluegill, common carp, green sunfish, redear sunfish on Patagonia Lake.
Creek inflow is the top-rated area: an inflow / creek mouth in about 7 ft of water that rates prime for rainbow trout in spring. The interactive chart above rates every spot for each species and season.
For rainbow trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Patagonia Lake is regulated by the Arizona Game & Fish Department. Check the official Arizona regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
