The Rio Grande/Río Bravo del Norte (hereinafter referred to as the “Rio Grande”) is the primary source of recharge to the Mesilla Basin/Conejos-Médanos aquifer system in the Mesilla Valley of New Mexico and Texas. The Mesilla Basin aquifer system is the U.S. part of the Mesilla Basin/Conejos-Médanos aquifer system and is the primary source of water supply to several communities along the United States–Mexico border in and near the Mesilla Valley. Identifying the gaining and losing reaches of the Rio Grande in the Mesilla Valley is therefore critical for managing the quality and quantity of surface and groundwater resources available to stakeholders in the Mesilla Valley and downstream. A gradient self-potential (SP) logging survey was completed in the Rio Grande across the Mesilla Valley between 26 June and 2 July 2020, to identify reaches where surface-water gains and losses were occurring by interpreting an estimate of the streaming-potential component of the electrostatic field in the river, measured during bankfull flow. The survey, completed as part of the Transboundary Aquifer Assessment Program, began at Leasburg Dam in New Mexico near the northern terminus of the Mesilla Valley and ended ~72 kilometers (km) downstream at Canutillo, Texas. Electric potential data indicated a net losing condition for ~32 km between the Leasburg Dam and Mesilla Diversion Dam in New Mexico, with one ~200-m long reach showing an isolated saline-groundwater gaining condition. Downstream from the Mesilla Diversion Dam, electric-potential data indicated a neutral-to-mild gaining condition for 12 km that transitioned to a mild-to-moderate gaining condition between 12 and ~22 km downstream from the dam, before transitioning back to a losing condition along the remaining 18 km of the survey reach. The interpreted gaining and losing reaches are substantiated by potentiometric surface mapping completed in hydrostratigraphic units of the Mesilla Basin aquifer system between 2010 and 2011, and corroborated by surface-water temperature and conductivity logging and relative median streamflow gains and losses, quantified from streamflow measurements made annually at 16 seepage-measurement stations along the survey reach between 1988 and 1998 and between 2004 and 2013. The gaining and losing reaches of the Rio Grande in the Mesilla Valley, interpreted from electric potential data, compare well with relative median streamflow gains and losses along the 72-km long survey reach.


ABSTRACT Three native trouts occur in the southwestern United States. The Rio Grande cutthroat trout <em>Oncorhynchus clarkii virginalis</em> persists in New Mexico and southern Colorado on the Santa Fe, Carson, and Rio Grande national forests and private lands. The Gila trout <em>O. gilae</em> and the Apache trout <em>O. gilae apache</em> (also known as <em>O. apache</em>) occur in isolated headwater streams of the Gila and Little Colorado rivers on the Gila and Apache- Sitgreaves national forests and Fort Apache Indian Reservation in southwestern New Mexico and east-central Arizona, respectively. For more than two decades, intensive management has been directed at the Apache, Gila, and Rio Grande cutthroat trouts. Despite the efforts, their decades-long listed status remains unchanged for the Gila and Apache trouts, and the Rio Grande native is under consideration for listing. The objectives of this paper are to review the literature and management activities over the past quarter of a century in order to delineate why recovery and conservation have been so difficult for southwestern trout.

Few traveling between Santa Fe, New Mexico, and the Rio Grande valley realize that they are traversing one of the most significant American Indian migration and settlement corridors in the Southwest, a well-watered and fertile floodplain that served to link peoples of the southern Rocky Mountains and the San Juan River to those of the Jemez range and Sangre de Cristo Mountains, and the Rio Grande, across some 300 miles. This chapter gives an overview of Pueblo (Tiwa, Tewa, Towa, Keres, Hopi, and Zuni), Apache, Navajo, and O’odham histories, and reveals a dual process of migration and place making across a millennium. The Southwest has a high variability in seasonal precipitation, and its peoples have demonstrated creative and adaptable cultures that allowed for movement to new locations and the creation of new homelands as a crucial aspect of their survival.
