Water quality and availability issues have impacted official bathing zones and local supplies in the Castilla y León region.

In El Bierzo, the Toral de los Vados stretch of the Burbia River was removed from the official list of natural bathing areas for the 2026 summer season after a 2025 evaluation rated its water quality as insufficient. This reduced the region’s count of recognized bathing zones from six to five.

Separately, the Toral de Merayo bathing area was forced to close due to a significant reduction in the Oza River’s water flow. This shortage has coincided with ongoing supply issues for approximately 20 days, leading to water restrictions and scheduled cuts to manage reservoir levels during peak consumption periods.
