Monitoring of water bodies in Hydrographic Region No. 5 – Tagus and Western rivers

In 2019, we implemented the River Habitat Survey (RHS) method, using a certified technician to monitor water bodies in the territorial areas managed by the APA departments in Hydrographic Region No. 5, which corresponds to the Tagus basin and western rivers. This monitoring aimed to improve and complement the criteria for classifying the status of inland surface water bodies. Over 100 sites were sampled, including large rivers, particularly stretches of the Tagus River, and a specific methodology was implemented for these sites.
