identify representatives from water user groups and other stakeholders. Organizations and<br />

individuals on the master stakeholder list were sent announcements of meetings and the RWP<br />

update process and progress.<br />

Over the two-year update process, 18 meetings were held in the <strong>Middle</strong> <strong>Rio</strong> <strong>Grande</strong> region,<br />

including 17 NMISC-facilitated meetings and an additional public forum. These meetings<br />

identified the program objectives, presented draft supply and demand calculations for discussion<br />

and to guide strategy development, and provided an opportunity for stakeholders to provide input<br />

on the strategies that they would like to see implemented. All steering committee meetings were<br />

open to the public and interested stakeholders, and participation from all meeting attendees was<br />

encouraged.<br />

Key <strong>Water</strong> Issues<br />

The key water supply updates and issues currently impacting the <strong>Middle</strong> <strong>Rio</strong> <strong>Grande</strong> region<br />

include the following:<br />

<br />

<br />

<br />

<br />

The climate divisions within the planning region have all experienced drought in recent<br />

years. This is a particular concern for agricultural users that are dependent on surface<br />

water, but drought preparedness is important for each community in the region.<br />

The <strong>Rio</strong> <strong>Grande</strong> Compact requires delivery of specified amounts of water to Elephant<br />

Butte Reservoir based on the annual natural flow of the <strong>Rio</strong> <strong>Grande</strong> at the Otowi gage.<br />

New Mexico’s delivery to Elephant Butte Reservoir under the Compact is dependent, in<br />

part, upon natural and man-caused depletions within parts of the Jemez y Sangre, <strong>Middle</strong><br />

<strong>Rio</strong> <strong>Grande</strong>, and Socorro-Sierra planning regions. This requirement limits combined<br />

depletions in these three regions. When the stored water in Elephant Butte and Caballo<br />

reservoirs legally available for release to the lower <strong>Rio</strong> <strong>Grande</strong> drops below a specified<br />

level, certain provisions of the Compact restrict storage and/or release of stored water in<br />

reservoirs upstream of Elephant Butte constructed after 1929, thus impacting water<br />

operations in the region, perhaps significantly.<br />

The <strong>Rio</strong> <strong>Grande</strong> is the main river in the planning region, and most of the groundwater in<br />

the region is within the <strong>Rio</strong> <strong>Grande</strong> Underground <strong>Water</strong> Basin and is considered to be<br />

stream-connected. The <strong>Rio</strong> <strong>Grande</strong> in the region is considered by the State Engineer to be<br />

fully appropriated, and any new diversion of surface water or stream-connected<br />

groundwater requires the transfer of a valid senior surface water right. The availability of<br />

senior water rights may thus be a limiting factor in meeting the future water needs of the<br />

region.<br />

<strong>Water</strong> users seeking to obtain water rights to meet growing demands, such as municipal<br />

users, are challenged because they must transfer an existing senior water right. No new<br />
