Immense opportunity for dam removal in the Duoro River basin
The UTAD research team found that the Duoro River basin is littered with barriers and the barriers are impacting this biodiverse area. Altogether, they found 1201 barriers – 57 dams, 40 mini-hydro, and 1105 medium and small barriers and dams. This number of small and medium-sized dams is in line with the recent estimations of the AMBER project, estimating 85% of in-stream barriers are small or medium-sized. The UTAD study estimates that about 25% of these barriers are abandoned.
