Colorado River Environmental Challenges

The Colorado River is crucial for water supply, irrigation, and power in the West, but faces challenges due to overuse, drought, and climate change. Water allocation agreements have proven inadequate, leading to environmental issues and declining water levels in reservoirs. The Salton Sea faces habitat loss and increased salinity. States and stakeholders are working together to find solutions, but difficult decisions lie ahead.

What is one of the primary uses of the Colorado River's water?

• To fill swimming pools in Nevada
