Río Júcar (Tramo Medio)

Río Júcar (Tramo Medio) terrain map

The Júcar's middle reach downstream of the Alarcón reservoir, where the river widens and warms into transitional water — still holding some brown trout in its cooler stretches but increasingly a barbel and mixed coarse fishery as it crosses the La Mancha plateau.

About this water

The Júcar's middle reach downstream of the Alarcón reservoir, where the river widens and warms into transitional water — still holding some brown trout in its cooler stretches but increasingly a barbel and mixed coarse fishery as it crosses the La Mancha plateau. Slower pools and longer glides than the headwaters.
