USEPA-Approved TMDL

for the Upper Gila,
San Francisco, &
Mimbres Watersheds

Horizontal Line - Divider

The Tularosa River, 2011

The Upper Gila, San Francisco, and Mimbres watersheds are located in southwestern quadrant of New Mexico, USA.   The Surface Water Quality Bureau (SWQB) conducted its most recent water quality surveys of the region in 2009 and 2011.

Water quality monitoring stations were located within these watersheds to evaluate the impact of tributary streams and ambient water quality conditions. As a result of assessing data generated during this monitoring effort, impairment determinations of New Mexico water quality standards (WQS) included:

Bulleted item

Cadmium and lead in Cold Springs Creek in the Mimbres watershed, Closed Basin;

Bulleted item

E. coli in Centerfire Creek, San Francisco River, South Fork Negrito Creek, and the Tularosa River of the San Francisco watershed, Gila River Basin; and Mimbres River in the Mimbres watershed, Closed Basin;

Bulleted item

Turbidity in Centerfire Creek, San Francisco River, and Tularosa River in the San Francisco River watershed, Gila River Basin; and

Bulleted item

Chronic aluminum in Willow Creek in the Upper Gila watershed, Gila River Basin.

This TMDL document addresses the above noted impairments as summarized in the tables found in the Executive Summary.  The 2009 and 2011 field studies identified other potential water quality impairments that are not addressed in this document due to additional data needs, assessment protocol revisions or re-application, or impending use attainability analyses.  If additional impairments are verified or found, subsequent TMDLs will be developed for those impairments.  SWQB has previously prepared TMDLs for portions of these watersheds including: TMDLs for conductivity and plant nutrients in Centerfire Creek (2001); a temperature TMDL for South Fork Negrito Creek (2001); TMDLs for temperature and plant nutrients in the San Francisco River (2001); and a TMDL for conductivity in the Tularosa River (2001).

A TMDL is a planning document that establishes specific goals to meet water quality standards in waterbodies where pollutant limits are exceeded. It includes current pollution loadings, reduction estimates for pollutants, information on probable sources of pollution, and suggestions to restore or protect the health of the waterbody.

A public meeting was held to summarize the information and to provide a forum for interested parties to ask questions and provide comments. The meeting date allowed the public time to review the document and generate questions or comments. The meeting was held in Silver City on Thursday, June 10 from 6-8pm at the City Hall Annex, 1203 N. Hudson Street.

A 30-day comment period on the initial draft of this document opened June 23, 2014 and closed on July 22, 2014 at 4:00 p.m. MDT.  No public comments were submitted during the Public Comment period to SWQB staff. The Final Draft was submitted to the Water Quality Control Commission (WQCC) for their approval on Tuesday, September 9, 2014 at their regular public meeting.  The WQCC approved the Final DRAFT TMDLs without comment.  Their approved document was quickly reviewed by the US EPA Region 6 Offices and received their final approval on September 11, 2014.

The SWQB’s Monitoring, Assessment & Standards Section is scheduled to collect water quality data in the Mimbres watershed in 2015 and the Gila River Basin in 2019.  TMDLs will be re-examined and potentially revised at those times as this document is considered to be an evolving management plan.  In the event that the new data indicate that the targets used in the analyses are not appropriate and/or if new standards are adopted, the TMDLs will be adjusted accordingly. When attainment of applicable water quality standards has been achieved, the impairment will be removed from New Mexico’s CWA §303(d) List of Impaired Waters (“§303(d) List”).

The SWQB’s Watershed Protection Section will continue to work with watershed groups to develop Watershed-Based Plans (WBPs) to implement strategies that attempt to correct the water quality impairments detailed in this document. Implementation of items detailed in the WBPs will be done with participation of all interested and affected parties.

For more information, please contact Meghan Bell of the Assessments & TMDL Team directly (see above).  The SWQB fax number is (505) 827-0160.
