The purpose of the Proposed Action is to deliver water from the Seven Rivers Augmentation Wellfield to Brantley Reservoir for use as Carlsbad Project water. The proposed augmentation well field pipeline would address two primary needs along the Pecos River. The NMISC needs to augment the Carlsbad Irrigation District (CID) water supply as partial fulfillment of the Settlement Agreement (see below); and as a member of CID and under the Pecos River Settlement Agreement, the NMISC needs to use Carlsbad Project water to maintain longterm compliance with the Pecos River Compact (Compact) and the United States Supreme Court Amended Decree in Texas v. New Mexico. Delivery of water from the augmentation well field has independent utility for the NMISC apart from the Settlement Agreement.
