Colorado River Water Delivery Agreement

An important source of supply for San Diego under the QSA is the Water Authority-Imperial Irrigation Water Transfer, which will bring up to 200,000 feet of water to the region by 2020. Minute 323 requires the U.S. to contribute $31.5 million to conservation projects in Mexico focused on improving infrastructure. These projects are expected to save about 200,000 acre-feet of water each year. The money will come not only from the U.S. government, but also from the Metropolitan Water District of Southern California, the Southern Nevada Water Authority, the Imperial Irrigation District, and the Central Arizona Water Conservation District. In return for their funding, these water agencies receive part of the water saved. In addition to funding conservation projects, the U.S. government and non-governmental organizations will fund $18 million for habitat restoration and monitoring. 1. Reduces California`s over-reliance on the Colorado River – QSA allows California to reduce its historically overspending on the Colorado River to its annual division of 4.4 million acre feet through voluntary water transfers from agriculture to the city and other water supply programs. The SQA is committed to establishing a Joint Power Authority (JPA QSA) to mitigate the negative effects of these water supply programs on Salton Lake. It also requires the state to put in place a recovery plan, the Salton Sea Management Program (SSMP), which provides a pathway for all impacts on Salton Lake outside of the QSA and all effects beyond what is required by the SQA JPA.

The SSMP will lead investments in Salton Lake to protect public health and ecosystem prosperity. Mexico agreed to take less water in times of drought, in exchange for setting up the intentionally created Mexican division. Mexico will be allowed to store water in Lake Mead during periods of surplus or if it cannot use its full annual allocation due to infrastructure issues. Minute 319 also solidified the ongoing water supply and environmental work in the Mexican delta. A sequel to Minute 319, called Minute 323, ended in September 2017. The agreement ensures a continuous flow of water to the Colorado River Delta and extends the restored habitat area from 1700 to 4,300 hectares. Mexico will continue to store water in Lake Mead and the two governments will provide funds and other resources for research projects along the border and throughout the region. The QSA is an important success in improving the long-term reliability of San Diego County`s water supply. Deliveries related to the agreement now account for nearly 38% of our region`s water and will continue to grow in the coming years. The quantification settlement agreement for the Colorado River was concluded in October 2003. This landmark agreement provides California with the opportunity to conduct water transfers and supply programs that allow California to live within the basic annual distribution of 4.4 million feet of colorado River water.

Among the agreements is the Minute 319 milestone, which contains an agreement between the United States and Mexico that partially resolves the question of when Mexico will accept a lack of deliveries from the Colorado River. In 2007, Mexico and the United States agreed on a formal process, managed by the IBWC, to discuss “a number of issues of mutual interest to the two nations related to the Colorado River.” The discussions resulted in a number of protocols (agreements) annexed to the 1944 treaty, which were to strengthen cooperation between the two countries in the management of the river. .
