The report finds that the implementation of ecological flows in Spain is largely a failure, with water administrations frequently prioritizing economic and agricultural demands over environmental objectives. While minimum flows have been extended to most water bodies in the third cycle, other critical components—such as maximum flows, flooding regimes, and change rates—remain poorly defined or unimplemented. The report highlights severe anomalies in the Tagus basin, where minimum flows are being implemented gradually until 2027 to protect water transfers to the Segura basin, and in the Ebro Delta, where a lack of sediment management and insufficient flows are leading to ecosystem regression. Across all basins, the report notes a lack of adaptive monitoring and a failure to integrate the specific water requirements of Natura 2000 protected areas into flow calculations.
