Hydroelectric Power

Question 1

How do dams help with generating hydroelectric power?

Answer 1

dams trap water which is then released and channeled through turbines which generate
electricity

Question 2

How are hydroelectric power plants used

for flood control?

Answer 2

During periods of heavy rain dams can
impound floodwater and then release them
under control. They can also store or divert
water for other uses.

Question 3

What issues are related

concerning flooding and sediment at dams?

Answer 3

As river water reaches the reservoir created by the dam, the water slows and
sediments deposit which lifts the riverbed and increases the vulnerability to flooding

Question 4

How do hydroelectric power plants affect salmon populations and water quality?

Answer 4

As river water reaches the reservoir created by the dam, the water slows and sediments deposit behind the dam,
which reduces water quality and reduces the life span of the dam and the amount of water it can impound
