Re: NM CAP Entity Proposed Action

Dear Ms. Meyers;

In December 2004, the Arizona Water Settlements Act (AWSA) allocated to New Mexico an annual
average of up to 14,000 acre?feet (AF) of additional water from the Gila basin.

The New Mexico CAP Entity (?Entity?), on July 11, 2016, chose in an open, public meeting its proposed
action as the diversion, conveyance, and storage alternatives identi?ed in the attached System Alternative
4 (Figure 1), and System Alternative 1 (Figure 2).

Alternative 4 is envisioned in two phases.

Initial Phase:
- Diversion of up to 150 near the Gila near Gila gage site.
0 Flood In?ltration and aquifer storage near the Gila Gage or alternative sites.
0 Three Ranney Wells near the Upper Gila ditch heading.

0 Phase 1 would recover in?ltrated AWSA water into the Upper Gila and Ft. West ditches and from
the Ft. West ditch to the Gila Farms ditch.

Additional Phase:

0 Construct Winn reservoir to 3,845 AF storage for canyover storage of water not conveyed in the
ditches.

- Pipeline from Gage site diversion to Winn canyon.
0 Additional in?ltration basins in the Cliff-Gila Valley.

0 Up to three additional Ranney collector wells in the Cliff-Gila Valley and pipelines to Winn
reservoir.

0 Recapture of in?ltration from Winn reservoir by Ranney well down gradient of Winn reservoir.
0 Pump (up to 75 cfs) and 54 inch pipeline from Winn Reservoir to Upper Gila ditch.

 

Alternative 1 Potential Spar reservoir phase
Utilized if demand not met in initial phases or if initial phases prove not feasible.

0 Where possible, utilizes infrastructure and elements (diversions, pumps, Ranney collector wells,
piping) of Phase 1 and/or Phase 2.

Spar pump station with surface or Ranney well supply it required.
- Construct Upper Spar reservoir up to 9,000 AF.
0 Return Line to Upper Gila Diversion

For all alternatives, direct capture of AWSA water and/or recovery of in?ltrated AWSA water in:
0 Existing Redrock and Virden Diversions (Figure 3)
0 Existing San Francisco Basin Diversions (Figure 4)

This proposed action is further described in the draft report Prepared for the New Mexico Unit of the
Central Arizona Project, dated July 8?1 2016, a feasibility level screening engineering evaluation of
alternatives prepared for the New Mexico Interstate Stream Commission by AECOM and Bohannon

Huston, lnc. and in collaboration with the Entity and has been posted at 
worklaecomldraft-phag-i-report

The Entity requests that the proposed action be carried forward in the New Mexico interstate Stream
Commission?s/Bureau of Reclamation's Joint NEPA analysis.

The Entity will continue to re?ne and develop more information on the proposed action and will provide
such information to the Bureau as it is developed.

It you have questions or require additional information please contact me.

Sincerely,

Anthony Gutierrez 

Executive Director New Mexico CAP Entity
