Fish Patagonia › Guides › Flies and Hatches for the Futaleufú, Yelcho and Palena
In short: The flies the app uses for this area: Parachute Adams, Pheasant Tail and CDC emerger (mayflies), Elk Hair Caddis, foam hoppers, cantaria beetles, foam dragonflies, pancora crabs, and Woolly Buggers or zonkers as streamers. When the water is high or blown out the app steers you to subsurface flies.

In summer the app suggests dry-dropper rigs, hoppers (Fat Albert / foam hopper #6–10), cantaria beetles (#8–12) and mayflies such as the Parachute Adams (#14–18).
The app lists Woolly Bugger (black / olive) (#4–8) and Zonker / sculpin (#2–6); Lago Yelcho is also fished with sinking lines along the deep edges.
The app switches to subsurface flies (nymphs and streamers) when flow is high or blown out, and points to the lakes when rivers run high.
Didymo biosecurity: avoid felt-soled boots (use rubber soles); soak boats, waders and nets for 5 min in 5% dish-soap, 2% chlorine or 5% salt solution and dry 48 h when changing watersheds.
Provisional data and general guidance. Conditions change quickly: scout, check local rules with Sernapesca and use a local guide on big water.
