CAP CanalThrough 2017, the Colorado River water CAP delivers has supported Arizona's gross state product (GSP) with $2 trillion in economic benefits since water deliveries began, according to a study commissioned by CAP with the W.P. Carey School of Business at Arizona State University.

The GSP represents the dollar values of all goods and services produced in the region and is a measurement of the economic output of a state, a counterpart to the gross domestic product for the nation.

In recent years, Colorado River water delivered by CAP has supported an economic benefit exceeding $100 billion per year, representing 40 percent of Arizona’s GSP. CAP’s supply of water to its customers in 2017 is estimated at annual employment of nearly 1.6 million jobs.
