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

La Zona is located very close to Concordia city right in front of the Uruguay River in the Entre Rios province, about 270 miles from Buenos Aires. La Zona is the exclusive area on the Uruguay River, downstream from Salto Grande Dam. This is a very restricted fishery. The area is only open four days per week, and only two boats can fish at one time.
2023 La Zona Lodge Hosted Week:
5-nights and 4-days guided fishing

La Zona freshwater golden dorado fishing is unrivaled in the world and is home to over 12 fly-fishing 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 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.
Six is the maximum number of anglers that can fish inside the exclusion area at the same time. The Lodge can accept larger groups by fishing half a day inside the exclusion area and half a day outside.
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. 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.
In April of 2012, our client Mike Sadar landed a world record fly-caught 50-pound golden dorado.
"...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.
The 13-hour guided fishing day is only available during peak season, from the last week of December through April. For the 13-hour day, you’ll have breakfast at 5:00 a.m. A packed lunch is provided. You’ll fish from 6:00 or 6:30 a.m. (depending on the sunrise) to 7:00 p.m.
Lodge Season: Peak season runs from the last week of December to late April when the Uruguay River is at its lowest. La Zona is a year-round fishery except for late October to mid-November, when the area is closed due to spawning.
Fishing is only allowed with flies and artificial lures. All Lures must be barbless hooks. During the regular season 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.
