Verified 2026-07-31: the Cabriel stretch from the foot of the Contreras dam upstream of Casa de la Huerta de las Escobas runs 1 Apr–30 Sep, single rod without abandonment, barbless hook, all common trout catch-and-release. The Comunidad Valenciana side of the CLM/CV border stretch closes 30 Aug specifically to keep both regions' seasons coordinated on this shared water — confirm which bank/jurisdiction applies before fishing near the border.
