650-acre reservoir near Utuado. A three-armed reservoir on the Río Grande de Arecibo near Utuado, reached by public launch boats, holding largemouth and peacock bass, tilapia, catfish and sunfish. The lake tops out around 69 ft. The depth chart comes from U.S. Geological Survey bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
Lago Dos Bocas's chart carries 9.2 miles of bank. A development index of 3.5 means a maze of bays and points: far more casting targets than a round bowl of the same size. The shallow band under 15 ft claims about 73% of the surface — that's where the groceries are. End to end it runs roughly 2.4 mi, about 1.2 mi across. Utuado County claims this one. If the bite dies, Lago Caonillas is 4 mi to the south.
When the water first warms, largemouth bass slide up into 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. If you only fish one area, make it Shallow bay flat: a weed flat around 6 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 (6 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Main-lake point (10 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (10 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (4 ft) | Blade bait, Jigging spoon |
Spring peacock bass (tucunaré) on Lago Dos Bocas hold shallow, usually 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. The chart's best answer is Main-lake point — point, 10 ft, prime for spring. Prime time lands in midday and early morning. The summer box starts with a topwater (walking bait) or a jerkbait.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 12 ft | midday & dawn | Main-lake point (10 ft) | Topwater prop bait, Jerkbait (fire tiger) |
| Summer | 3 to 15 ft | midday & dawn | Main-lake point (10 ft) | Topwater (walking bait), Jerkbait |
| Fall | 3 to 15 ft | midday & dawn | Main-lake point (10 ft) | Jerkbait, Swimbait |
| Winter | 6 to 22 ft | midday | Break off the point (4 ft) | Slow jerkbait, Jig |
Come spring, look for tilapia tight to the bank in 1 to 6 ft. Expect a summer slide to 2 to 10 ft, then a winter hold in 5 to 18 ft. Start at Shallow bay flat. It's a weed flat holding about 6 ft of water and rates prime come spring. Prime time lands in midday and early morning. A micro-jig near weed edges is the honest summer answer here.
| 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 |
| Summer | 2 to 10 ft | midday & dawn | Shallow bay flat (6 ft) | Micro-jig near weed edges |
| Fall | 3 to 12 ft | midday | Shallow bay flat (6 ft) | Small jig tipped with worm |
| Winter | 5 to 18 ft | midday | Break off the point (4 ft) | Slow micro-jig, warm outflows |
When the water first warms, channel catfish slide up into 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. If you only fish one area, make it Río Limón inflow: an inflow / creek mouth around 7 ft that scores prime in spring. 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 | Río Limón inflow (7 ft) | |
| Summer | 8 to 25 ft | night & dusk | Río Limón inflow (7 ft) | |
| Fall | 10 to 30 ft | dusk | Old creek channel (2 ft) | |
| Winter | 20 to 40 ft | midday | Deep basin (69 ft) |
When the water first warms, bluegill slide up into 1 to 6 ft. Summer is a 4 to 15 ft game here, winter a 10 to 25 ft one. Start at Shallow bay flat. It's a weed flat holding about 6 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 (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 | Deep basin (69 ft) | Tiny spoon |
Structure-wise the chart holds 9 features, led in depth by Deep basin at roughly 69 ft.
