This can lead to a decline in biodiversity and an increase in the risk of extinction.<\/li>\n<li>Altering flow patterns: Dams and river diversions can alter flow patterns by reducing the amount of water flowing downstream. This can lead to changes in water temperature, sediment transport, and water quality. These changes can have a negative impact on aquatic ecosystems and the plants and animals that live in them.<\/li>\n<li>Reducing fish populations: Dams and river diversions can reduce fish populations by blocking fish migration, altering water temperature and flow patterns, and creating changes in water quality.

For example, dams can increase the risk of flooding downstream, which can damage aquatic habitats and the plants and animals that live in them. Dams can also alter the timing of flooding, which can disrupt the life cycles of aquatic organisms.<\/p>\n<p>Overall, dams and river diversions can have a significant negative impact on river ecosystems.
