Final answer:
The statement is True. Existing treaties on the Colorado River allocate more water than its typical total annual stream flow to various water users such as states, cities, and agriculture.
Step-by-step explanation:
The statement is True. Existing treaties on the Colorado River do allocate more water than its typical total annual stream flow.
The Colorado River has an average annual flow of 17.5 million acre-feet, but the existing treaties allocate more than that amount to various water users such as states, cities, and agriculture. These treaties were negotiated over time to allocate the water resources of the Colorado River basin among the seven states that rely on it.
Despite the fact that the allocated water exceeds the river's annual flow, efficient water management and successful conservation efforts ensure that water needs are met.
