Fish would not be able to migrate up the river to reproduce.
Sediment carried by the flowing river would get trapped.
There would be more space for forest growth.
The number of habitats for local wildlife would increase.
Birds that depend on fish may go hungry.

Answer 1

Dams can affect the resources of the local watershed by preventing fish migration, trapping sediment, and impacting bird food sources.

Step-by-step explanation:

When a dam is built, it can have several effects on the resources of the local watershed. First, fish may not be able to migrate up the river to reproduce, which can impact their population numbers. Second, sediment carried by the flowing river can get trapped in the reservoir created by the dam, which can affect the water quality and the habitat for aquatic organisms. Finally, birds that depend on fish may go hungry if the dams prevent fish from migrating, reducing their food source.
