The plan
Plan A

Start with Microtricóptero de Becada (18-20) on a As per local method. If that does not produce, switch depth or speed before changing the pattern entirely.

Plan B

A fry-imitating pattern stripped through the margins can save a blank in autumn.

Watch for

Terrestrials may strengthen through the middle of the day as conditions warm.

Bank, sheltered shores

In wind, bank fish the lee shore — boats can anchor in productive areas if conditions allow.

About this water

A reservoir near Corvera/Avilés that formerly served as a coto intensivo for put-and-take rainbow trout. Like the other city-adjacent intensivos (San Andrés, La Granda), there is no clear evidence of current trout stocking. The 2016 critique of salmonid management in Asturias noted that restocking programmes were often poorly managed, and the pattern since COVID has been one of quiet decline rather than intentional phase-out. What remains is a mixed coarse fishery dominated by carp with occasional brown trout. For a genuinely stocked Asturian stillwater, El Arenero at Tineo is the realistic option.
