The Colorado River supplies water for approximately 30 million people. It is one of the most carefully controlled rivers on Earth.
The river experiences wet and dry periods that can last for years. Years with more Moisture that falls from the air to the ground. Includes rain, snow, hail, sleet, drizzle, fog and mist., such as 1983-1987, result in more reliable river flow.
