Local Leagues in New Mexico

LWVNM STUDY OF
Water Supply and Demand, 2007-2010

At its 2007 state Convention, the League of Women Voters of New Mexico approved a two-year study of Water Supply and Demand. The League would like to develop a statewide position on the allocation of available water among competing uses, grounded in a basic understanding of NM water availability and water law. A third year was approved at the 2009 state Convention. Consensus questions will deal with

Most of the NM Leagues have studied water issues in the past but the resulting positions may not be applied at the state level without statewide consensus. See the existing local positions.

Public Welfare

The New Mexico Water Code obliges the State Engineer to consider "public welfare" when allocating water or approving water transfers. However, the state has never formally defined public welfare, although New Mexico courts have held that the term should be construed broadly to include health and safety, recreational, aesthetic, environmental and economic interests. Consideration of public welfare raises difficult economic, environmental and social issues. Nevertheless, the public welfare requirement does establish a mechanism to broaden the protection of water resources.

Consuelo Bokum (NM Environmental Law Center, no date). Implementing the Public Welfare Requirement in New Mexico's Water Code (PDF 128 KB). This report reviews the public trust doctrine underlying the authority given to the State Engineer to protect the "public welfare" and argues that the term should be defined broadly, supplying a draft definition and standards for its implementation.

Water and Land Use

"Historically, land-use and water planning have occurred separately from one another. Water is allocated by state agencies, and land-use planning is done by local officials." (Watering the West, Headwaters News, March 15, 2007.)

The San Juan/Chama Project (PDF 84 kB) diverts about 110,000 acre-feet per year (afy) of water from the Colorado River Basin across the continental divide into the Rio Grande Basin. More than half of this is destined for the Middle Rio Grande region. Albuquerque completed its San Juan Drinking Water Project in December 2008. Eventually the project will provide 70-90% of the metro area's water. The former system, relying entirely on pumping groundwater, was removing water from the aquifer twice as fast as it could be replaced.
