How does water diversion affect the environment?
Negative impacts of dams and agricultural diversions include: Habitat fragmentation – blocks fish passage. Reduction in streamflow downstream, which then results in changes in sediment transport, and in floodplain flooding. Changes in water temperature downstream from dam.
