The most practical fly day from Zaragoza, and honest about what it is: a stocked coto on the Isuela reservoir under the limestone shoulders of the Sierra de Guara, an hour up the road from the city. Nobody will mistake it for a wild Pyrenean stream, but a stocked reservoir fished well on a buzzer or a slow nymph is a real day's fishing, and on a spring morning before the heat comes off the rock it can be a good one. Rainbows make up most of the stock; the odd brown turns up. It is the right answer when the mountain rivers are blown out, or simply too far for the hours you have.
Good drifting conditions on Embalse de Arguis (Río Isuela coto deportivo)
Good wave on — drift country. A useful wave. Work the productive shore.
No strong hatch signals at the moment — general searching tactics should work best. The ripple is helpful — fish should move onto the feed and a slow-drifted team or single wet will cover water well. Dusk on the lake is prime time for surface feeding — stay out as long as light allows.

When

Where
Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
Today's tactical plan
The plan
Plan A · Plan B · what to watch · bank or boat
The plan
Plan A
Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
Plan B
If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.
Watch for
Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.
Boat — drift
A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.
