“…In response, water authorities have utilized surface flows of the Rio Grande to provide additional volumes of water beyond what can be extracted from the two aquifers. A mix of conservation efforts have also been utilized for more than a decade to lower per capita demands [Schmandt, 2002]. Expanding populations in both El Paso and Ciudad Juárez imply increased consumption levels are still likely to be observed even as usage efficiency improves [Fullerton and Tinajero, 2003].…”

Time series analysis of water consumption patterns has been the subject of increasing attention in recent years. For many municipalities such efforts offer a means for developing potentially useful planning tools. Because data requirements are not extensive, model development is feasible for markets where information is limited. The work at hand examines the applicability of such a tool in El Paso, Texas, a growing metropolitan economy located in a semiarid region. Sample data are from January 1994 through December 2002. In addition to estimating a linear transfer function equation of water consumption in this city the model is subjected to a series of simulation benchmark tests.

“…The Lower Rio Grande Valley NWR has Class A and B water rights, but if water is scarce, allocations may be curtailed, making water shortages an issue for conservation of habitats such as rare flood-plain riparian forests. Although the legal settlement in 1969 attempted to fix problems with water allocation, water in the LRGV is still often overallocated, which can create conflicts among users (Stubbs and others, 2003) and even an uncertain international future as human populations and needs grow (Schmandt, 2002).…”

AbstractThe Lower Rio Grande Valley (LRGV) of southern Texas is located on the United States-Mexico borderland and represents a 240-kilometer (150-mile) linear stretch that ends at the Gulf of Mexico. The LRGV represents a unique transition between temperate and tropical conditions and,

“…As a result, the environment has deteriorated; signs of this deterioration are: progressive channel narrowing (Dean and Schmidt 2010), flow alteration due to reservoir operation (Sandoval-Solis et al 2010, invasion of nonnative species, e.g., salt cedar (Tamarisk spp.) and giant cane (Arundo donax) (Everitt 1998), change from freshwater to estuarine ecosystem (Schmandt 2002) and the almost complete extinction of endemic riverine species, e.g., Rio Grande silvery minnow (Hybognathus amarus) (Bestgen and Platania 1991).…”

In the Rio Grande transboundary basin, environmental flows have not been considered as an integral part of the water management. This research focuses on the Big Bend, a reach located along the Rio Grande mainstem. Important natural regions of the Chihuahuan Desert are threatened due to the lack of environmental flows. In this paper is estimated the maximum volume of water available for environmental flows without affecting human and international water requirements, and without increasing the flood risk in Presidio-Ojinaga. Environmental flows are proposed based on an analysis of the prior reservoir alteration hydrology of the river. A planning model was built to simulate the water allocation system and evaluate alternative policies. A reservoir reoperation policy for Luis L. Leon reservoir is proposed to supply environmental flows without violating the system constraints. The policy that supplies the maximum water to the environment is two-thirds (66%) of the prior reservoir alteration conditions; it also improves human water supply, treaty obligations, and decreases flood risk.
