Mike Sadar's world-record fly-caught dorado - 2012.

La Zona, "The Zone," is on the Uruguay River in the Entre Rios province, about 270 miles from Buenos Aires. La Zona is the exclusive and Restricted Zone on the Uruguay River, downstream from Salto Grande Dam. The area is only open four days per week, and only two boats from the Argentina side and two boats from the Uruguay side can fish at one time. This is a very restricted fishery. Our client Mike Sadar landed a world record fly-caught 50-pound golden dorado at La Zona in April 2012.
La Zona freshwater golden dorado fishing is unrivaled and is home to over 12 world records. The shallow lake generated by the nearby dam supports an abundant and very complex food chain. Here, many species, including the dorado, achieve unprecedented growth rates.
More than 300 fish of over 40 pounds were landed at La Zona in the past three seasons. The Uruguay River is a tailwater below the large Salto Grande Reservoir.
La Zona Lodge, which has exclusive rights to the Argentine side of the river, can fish a maximum of six anglers at a time inside the Restricted Zone.
La Zona is a unique fishery where dorado reach incredible sizes and numbers due to the impressive amount of food available and the very restricted fishing pressure. Anglers usually average 15 to 25 strikes per day. Fish average about 14 pounds with a chance at dorado over 50 pounds. Twenty-pounders are commonplace.
"...I feel that starting the drift 500 meters away from the dam walls puts the angler in a better position to catch true giants, as evidenced by our results. - In my opinion, La Zona is the world's greatest freshwater fishery."
- Bob Daly - Peacock Bass e-Zine
New Program: La Zona offers 8-hours, 10-hours, 11-hours, and 13-hours-per-day guided fishing packages.

During the regular or spring season - August 15 through October - the river is at its normal flow, and huge schools of big dorado migrate to the dam to spawn. Rapala X-Raps and similar crankbaits are hot during this time.
