León reservoir long noted for big carp alongside trout. One of Spain's clearer named stillwater carp-on-the-fly options — warm, sheltered margins and large fish that cruise the shallows in summer. Brown trout also persist in cooler inflow influence. This is a distinct stillwater venue, but it is directly connected to the Río Luna because it dams the upper Luna valley and shares part of that river system's identity.
