Sea Trout Of The Rio Gallegos  & Timing Your Booking

Sea Run Brown Trout fishing on the Rio Gallegos is a must for serious sea trout and salmon anglers, especially those who have already fished the Rio Grande. The Rio Gallegos is full of character and challenges, and it on par with the Rio Grande in both Sea Run Brown Trout population and the number of 20–30 lb fish.

The Gallegos River lies in the Santa Cruz province of Patagonia, Argentina, and stretches roughly 185 miles from the southern Andes Mountains to the Atlantic Ocean. Unlike the Rio Grande, the Rio Gallegos features high, rocky cliffs, random boulders on the riverbed, and willow trees dotting the river corridor. Wildlife — including guanacos (wild relatives of llamas), silver foxes, flamingos, geese, ducks, and grebes — is spotted at almost every pool. In mid-March, Ashy-headed Geese congregate in huge flocks along the river before heading north for the winter.

An estimated 70–90,000 Sea Run Brown Trout return to the Rio Gallegos every year, yet they distribute themselves in the relatively shallow water as they migrate upriver. These sea trout are often scattered across several holding lies within a given pool or run. Because fish are less concentrated than on the deeper, slightly shorter Rio Grande in Tierra del Fuego, targeted and stealthy presentations are often needed for success. With the help of a guide, anglers achieve this using smaller flies and 9 ft leaders on either a single-handed rod with floating or intermediate lines, or double-handed rods with a Scandi-style floating body and an intermediate or floating tip. This style of fishing appeals to many Atlantic Salmon enthusiasts. Every angler should carry a variety of sink tips to effectively fish the occasional deep pool.

Timing Your Week

Sea Run Browns begin entering the Rio Gallegos in November, but January, February, and March are the peak months and when most anglers wish to go.  In January, most fish are sea-bright chromers, though fresh, silvery fish are present throughout the season. By April, spawning beds appear in the middle to upper portions of the river, and by May 1st, sea trout are also spawning in the Penitente and Rubens tributaries. By mid-June, returning fish are back in the Rio Gallegos estuary, fattening up over the winter.
River conditions do play a major role in success; even in peak mid-summer, conditions can change quickly and adversely affect catch rates. Regardless of the month, if conditions are good, the fishing is generally excellent all along the Rio Gallegos.

Timing Your Booking

As with the Rio Grande, it is critical to secure your week on the Rio Gallegos shortly after the season ends in mid-April. The lodges on the Rio Gallegos do not use a strict First Right of Refusal policy, where each angler holds the right to take or decline their same week the following year. That said, anglers who have fished multiple seasons typically rebook before they checkout or very shortly after. By sometime in May, the lodges know which anglers are returning and which dates will be made available to others. Anglers hoping to get on the river should contact us by March of the year prior. We’ll help you evaluate your options and work directly with the lodges to secure your spot before their calendars open to the public and fill up.

There is a big difference in outcomes between letting us work for you and waiting until late May to see what remains. And remember — you never pay a dime more for our services.

For guidance on which lodge and when, just drop us a line. We’d be delighted to help you as well.
