THE CHICKASAW NATION HOSTED THIS RESEARCH SYMPOSIUM ON MARCH 22-24, 2022, HELD AT THE CHICKASAW RETREAT AND CONFERENCE CENTER IN SULPHUR, OK. After the Climate Workshop for The Chickasaw Nation in 2019, the Tribal managers discussed the need to include culture in conservation efforts and decided to seek a grant for culturally significant plants. This event was organized and led by the Chickasaw Nation and was funded by the U.S. Geological Survey through the South Central Climate Adaptation Science Center. There were 106 attendees with 75 Native representatives from 21 different tribes. There were 11 student attendees. Attendees came from all across the United States including Maine, New York, Michigan, Montana,...

The main source of surface water for irrigation in the study area is the Rio Grande River. The upstream reservoirs, Elephant Butte and Caballo, are used to regulate river flow into the study area. In order to estimate the future surface water availability, we developed a model and routed the reservoir inflow projections at the USGS San Marcial through the reservoir system. The data are available in csv worksheet as open source for free public use.

Groundwater resources are important for irrigated agricultural activities in the region. Farmers use groundwater to compensate for insufficient surface water availability. The data are stored in a csv file titled 'Monthly Groundwater Projections' (groundwater_availability_projections.csv). The columns represent monthly groundwater pumping rates (m3/day) while the rows represent months and dates. The data are open source and available for free public use.

The Ogallala Aquifer (OA) is a groundwater source beneath 111 million acres of Wyoming, South Dakota, Nebraska, Kansas, Colorado, Oklahoma, Texas, and New Mexico. It provides water for aquatic, riparian, range, and agricultural ecosystems as well as approximately 1.9 million people. The various social, economic, and ecological challenges of managing the aquifer are expected to increase with climate change. Hotter, drier summers are expected to increase already unsustainable demands on the aquifer’s water. There has been little success in reducing the rate of depletion, in spite of a preponderance of data available to support research, resource management, and outreach. Prior to this project, there was no single...

The Middle Rio Grande Hydroeconomic Optimization Model, also referenced as "The Bucket Model”, is a simple coarse-scale basin model that simulates all major water sources, sinks, uses, and losses. It also includes economic values of water, as well as institutional constraints governing water supply and use for the Middle Rio Grande between the inflow to Elephant Butte Reservoir and Fort Quitman on the Rio Grande. This model is designed to be a useful tool for improving our understanding of the hydrology, agronomy, institutions, and economics to guide analysis of policy and management questions that are important to stakeholders. The current version of the model is an aggregate “three bucket” model that reflects...
Projected changes to spring phenological indicators (such as first leaf and first bloom) are of importance to assessing the impacts of climate change on ecosystems and species. The risk of false springs (when a killing freeze occurs after plants of interest bloom), which can cause ecological and economic damage, is also projected to change across much of the United States. Given the coarse nature of global climate models, downscaled climate projections have commonly been used to assess local changes in spring phenological indices. Few studies that examine the influence of the sources of uncertainty sources in the downscaling approach on projections of phenological changes. This study examines the influence of sources...

Riparian forests have declined in the Middle Rio Grande, from upstream Elephant Butte Reservoir in NM, to Presidio, TX, where water stress is increasing due to human water withdrawals coupled with climate variability and change. To inform the dialogue about the feasibility and impact of providing environmental flows to maintain the riparian forests, we developed scenarios of surface water availability in the Middle Rio Grande under projected climate conditions. We also used state-of-the art hydrologic and hydroeconomic models to evaluate environmental flow allocations and associated water management tradeoffs under current and projected climate conditions. Our results indicate that water managers in the Middle Rio...

Led by universities of the South Central CASC, this project builds on the successes of three prior workshops to mentor a cohort of early-career environmental professionals in the South Central U.S. to serve as part of the next generation of USGS leaders and partners. The workshop objectives are to: (1) develop the participants’ knowledge, leadership skills, and interdisciplinary collaboration with an eye toward filling future USGS (or partner organization) positions; (2) introduce participants to the goals, structure, and unique research-related challenges of the South Central CASC and the larger CASC network; (3) guide participants to discuss their research beyond their disciplinary niche and with managers across...

Drought events have cost the U.S. nearly $245 billion since 1980, with costs ranging from $2 to $44 billion in any given year. However, these socio-economic losses are not the only impacts of drought. Ecosystems, fish, wildlife, and plants also suffer, and these types of drought impacts are becoming more commonplace. Further, ecosystems that recover from drought are now doing so under different climate conditions than they have experienced in the past few centuries. As temperature and precipitation patterns change, “transformational drought”, or drought events that can permanently and irreversibly alter ecosystems – such as forests converting to grasslands – are a growing threat. This type of drought has cascading...

The ecosystem of a river is dependent on the climate of the region. The amount of rainfall can impact the flow of the river and the water levels and temperature of the air can impact the temperature of the river. Some species, such as freshwater mussels, that exist in many rivers in Central Texas, are very sensitive to the temperature and amount of water in the river. In this study, we use the Texas fatmucket freshwater mussel species (Lampsilis bracteata) as a case study to understand impacts to freshwater mussels due to climate changes in the San Saba and Llano rivers of Central Texas. In central Texas, rainfall is expected to decrease while temperature increases as the climate changes. Drought and flooding events...

We review over twenty years of publications on Soil and Water Assessment Tool (SWAT) applications in arid/semi-arid irrigated agricultural watersheds. Our review reveals strict dominance of the model's use for better understanding water quantity aspects of water management. While this is to be expected given the reality of water scarcity and associated challenges for agricultural production systems in arid/semi-arid regions, the capabilities of SWAT to model water quality have been underutilized. The main modeling challenges are lack of observational data, poor data quality, concerns about simulation accuracy, and technical limitations of the model despite numerous advancements in the last two decades. To deal with...
