The Most Powerful Freshwater Fish on Earth — In One of the Most Exclusive Fisheries Ever Opened
Hidden below the massive Salto Grande Dam on the Uruguay River lies one of the most extraordinary freshwater fisheries on the planet. Anglers around the world know this place by one name:
La Zona — “The Zone” of Giant Golden Dorado
This short tailwater stretch, restricted to the general public and fished under strict government control, is famous for producing multiple IGFA world records, including two All-Tackle records. Few places on Earth can match the sheer size, density, and aggressiveness of the dorado that inhabit these currents.
For years, this area remained closed to outside anglers. Now, it has been reopened under a tightly controlled charter system — and WorldwideFishingDestinations.com can take you there.

WHY THIS DESTINATION IS LEGENDARY
Proven World-Record Waters
During the three original seasons when controlled fishing was allowed here, anglers broke:
8 IGFA world records
3 baitcasting records
3 fly-fishing records
2 All-Tackle World Records
One of these All-Tackle World Records still stands today, making La Zona one of the only freshwater destinations in the world with an active world-record pedigree.
These are not occasional monsters — this tailwater produces giant fish consistently.

The Fishery — Why Dorado Grow So Big Here
The Salto Grande tailwater is a perfect storm of big-fish biology:
1. High Oxygenation From the Dam Release
Cold, oxygen-rich water pouring from the turbines creates the ideal feeding environment for golden dorado.
2. Immense Baitfish Population
Shad-like sabalo and other forage fish stack up beneath the dam, drawing dorado into tight feeding zones where they grow huge.
3. Limited Fishing Pressure
Only 2 guided boats operate here per session.
No commercial fishing.
No crowds.
Basically no angling pressure.
4. Constant Current = Constant Feeding
Power generation keeps the river moving, so fish feed aggressively throughout the day. This creates explosive action, even in broad daylight.
5. Perfect Habitat for Ambush Predators
Slackwater pockets, swirling seams, and strong hydraulic flows create ambush points where dorado crush lures and flies with violent strikes.

CATCH RATES & FISH SIZE
Past seasons averaged:
🔥 22 dorado per boat per day
🔥 1 out of every 3 fish weighed over 15 lbs (6.8 kg)
🔥 Numerous fish in the 25–40 lb range
🔥 Legitimate shots at 50-lb class dorado
For fly fishermen, this is one of the best places on Earth to hook a true monster on an 8- to 10-weight rod.
For baitcasting anglers, the sheer power of these fish will test the strongest gear you own.
