chimehuin
The Chimehuin river put Argentina on the international fly-fishing map when Joe Brooks and friends first fished Patagonia.
This is a classic big freestone river with brown trout large enough to deserve the shaded deep willow lined banks. It is similar to the Madison River with true pools and runs. In places the river braids into a maze of willow lined channels with the feel of small water and the ever present possibility of big fish. Average rainbows and browns range between 15-20 inches with good numbers of fish up to 24 inches and some well beyond. All methods of fishing can be effective- prospecting with streamers, nymphs, and large attractor dry flies, spot fishing, or matching the sometimes prolific hatches. Throughout January and sometimes into February, a large ( size 8 & 10) mayfly similar to a Hexagenia or Yellow Drake, hatches most evenings.

There are some smaller mayflies which look like PMD's in February and sporadic but dense caddis hatches all season. Afternoon hopper fishing throughout the season In the fall the streamer fishing can be excellent for browns moving up out of the Collon Cura and the lower Chimehuin on their way to spawn. The last few years there have been impressive hatches of Mahogany mayflies in a size14 starting with the colder weather of late March-early April and continuing through till the end of the season. Every year on the Chimehuin fall browns are landed in the 10 Lbs plus range. Day floats on the Allumine and the Collon Cura are a comfortable distance from the estancia and a popular option. The estancia also offers hunting for red stag in late March through April.
