Hoover Dam’s Lake Mead reaches all-time low

Lake Mead, the largest US reservoir, has reached its lowest water level due to a prolonged drought, affecting water supply and energy production. The Hoover Dam's energy capacity has decreased by 25%, and further declines are expected. Las Vegas has banned non-functional grass to conserve water, as the Colorado River system faces historically low inflows.

What is the primary reason for the drop in water levels at Lake Mead?

• Increased rainfall

• Increased water usage

• Construction activities

• Prolonged drought

How does the water shortage at Lake Mead affect the Hoover Dam?

• It increases energy production

• It reduces energy production

• It has no effect on energy production

• It causes structural damage to the dam

By what percentage has the Hoover Dam's energy capacity already dropped?

• 75%

• 25%

• 10%

• 50%

What measure has Las Vegas taken to conserve water?

• Increased water prices

• Banned all outdoor water usage

• Banned non-essential grass

• Limited household water supply

What has been the impact of the drought on the Colorado River system?

• It has remained stable

• It has declined to half its capacity

• It has overflowed
