There is a low annual precipitation, an unreliable rainfall pattern and a significant seasonal imbalance on the Colorado River basin. The north of the basin receives significantly more precipitation than the south.
There is the possibility of transferring water from an area with a water surplus to an area of deficit by means of an aqueduct, canal or river. This will provide a regular, reliable water supply for expanding urban areas, industry and agriculture.
Sudden increases of river flow from seasonal precipitation or snow melting can bring a chance of flooding. Dams can be used to contain and regulate this flow.
There is irrigation potential for farming in areas such as Arizona, with a ready market and easy transportation links.
Hydroelectric power can come from dams such as the Hoover and Powell dams.
This will generate power for industry, farms and communities in cities such as Las Vegas. This will provide jobs and stimulate the local economy.
The area has geology suitable for the construction and storage of water.
Finally, this will improve the navigation potential of the river, by regulating flow.
The graph above reinforces the need for water management on the Colorado as precipitation is generally low and urban populations are rapidly growing.
