Fly fishing in Patagonia is a unique experience. Imagine casting to big, healthy trout in crystal clear water without seeing another person all day. There are miles of still and moving waters throughout Nahuel Huapi National Park with very little fishing pressure. Our waters offer a complete variety of different types of fishing, from big dry flies and weighted streamers to tiny emergers, nymphs and spinners. We fish both floating and sinking lines, dry and wet flies at different times of the season and throughout the day. When fishing the Manso River, much of your fishing will be with streamers and sinking lines. Hatches on much of the river are sporadic and the biggest fish are best drawn out with streamer patterns. There are several sections where nymphs are especially effective, and a tiny spring creek where sight casting to cruising fish can be a delightful change of pace.

The Channels of the river emptying Lago Hess are justly famous for their unique blend of big fish and technical fishing. The Channels’ smooth currents provide a great dry fly challenge for any angler. Similar in nature to a big spring creek, large fish often cruise this area or setup along the banks making this a required stop for any Rio Manso angler. Even though the fish can be selective, for many guests this is their favorite section. For good reason: some of the largest fish in the watershed live in this area.

One of the jewels at Rio Manso Lodge is Lago Fonck. This four mile long lake offers big rainbows, browns and brook trout. Depending on the time of year, we fish streamers and dry flies on the lake, often both during a typical day. Dragon flies, damsels, and caddis flies all hatch on the lake and the trout cruise the lakeshore weed beds in search of a meal. We fish the edges from one of our Carolina skiffs, working the structure where rainbow and brook trout lay, with the occasional brown as well. With the added bonus of spotting an Andean Condor circling overhead, and beautiful Mount Tronador in the distance, a day on Fonck is always special.

 

Our Season

The fishing season in Argentina runs from the beginning of November until the end of April. It is the exact opposite of the North American season, with our longest day of the year falling on December 21. Rio Manso Lodge is open for the entire season. Here’s an idea of what to expect:

 

Early Season: Early November – Mid January

These months are often marked by high water, which gradually recedes in December. We’ll start the season fishing lots of weighted streamers on sinking lines. Mayfly and caddis hatches beginning in November will intensify in December providing increasingly better dry fly fishing. Early to middle December will see dragonflies hatching on the lakes and rivers bringing up the biggest fish and providing exciting dry fly action. Dragon fly nymphs and wooly buggers are very effective at this time.

Summer Season: Late January – Mid March

Excellent evening dry fly action continues into January. The river channels near the lodge feature multiple mayfly and caddis hatches that bring the fish up, especially early and late in the day. As temps warm in February, day time fishing can slow down on both the river and in the lakes. Terrestrials play an increasingly important role in the daily diet as summer progresses.

Fall Season: Late March — End of April

As Fall approaches, water temperatures begin to cool and the fish become more active. Evening fishing is characterized by a brief flurry of activity right before dark while most daytime fishing is with streamers or large attractor dry flies. Big rubber legged dries work well in the lakes. April is when the big browns become aggressive prior to spawning season.

 

The Rio Manso Day

If you’ve fished with a guide, outfitter or lodge in North America, our daily schedule will feel quite familiar. Unlike most lodges, however, we are usually out on the water for 9–10 hours. If you really like to fish, you’ll love the length of our fishing day. For those who consider fishing just one part of a great Patagonia experience, we’re happy to bring you in whenever you’re ready.

While there is no such thing as an ordinary day at Rio Manso Lodge, we do have sort of a routine that begins most days with breakfast at 8am. After hot coffee, eggs, cereal, fresh fruit or whatever else you need to get going, you’ll meet your guide in the wader room around 9am. With the exception of a trip to the Pichi Leufu, Lower Manso, or a horse ride into Lago Los Cesares for big brookies and bigger browns, none of our waters are more than 20–25 minutes from the lodge which allows you to spend more time fishing and less time riding around. When departing for the Pichi, or Cesares, you will have breakfast at 7:30am.

We fish until mid-day, then stop for a streamside lunch which might include such items as steaks, quiches, sandwiches, salads, cheese, and fresh bread. Some of our guests like to take a siesta after lunch, but we’re not surprised if you want to get right back on the water!

After fishing through the afternoon, you would normally get off the water by 7–8 pm or so, and return to the lodge to clean up, take a sauna, or perhaps get a massage. We serve drinks and hors d’oeuvres before dinner in front of the fireplace. Dinner is usually served between 9 and 10 o’clock, although we’ve been known to eat much later if the fish are rising and you just can’t tear yourself away.

We are very flexible when it comes to arranging your day. If you have a special request, just let us know and we will do our best to accommodate you to give you the best experience possible.
