North Fork Red River Aquifer Study
In 2012 the U.S. Geological Survey, in cooperation with the OWRB, began an update of the hydrologic investigation and development of a groundwater-flow model for the North Fork Red River alluvial aquifer in Beckham, Greer, Jackson, and Kiowa Counties.
Upper Washita River Alluvial Aquifer Study
This project is a detailed study of the groundwater and surface water, the hydrogeology, climate, and base flow to streams, and the effects of water use and changes in weather and climate on the hydrologic system. The study includes field collection of groundwater and streamflow data, mapping the water table, aquifer base, and water use.
Salt Fork Red River Alluvial Aquifer Study
The objectives of this project are to describe the hydrogeology of the Salt Fork Red River alluvial aquifer and to produce numerical groundwater-flow models that can be used to simulate the transient groundwater-flow system. The Oklahoma Water Resources Board (OWRB) will use the outcomes from this project to determine the MAY and effects of future water extraction and drought. The geographic...
Red River Water Availability and Use and Ecological Characteristics Focus Area Study
Staff members of the Oklahoma Water Science Center in Oklahoma City and of the Oklahoma Coop Unit at Stillwater are working with USGS staff members from Water Science Centers in Arkansas, Louisiana, Texas, and New Jersey to conduct a comprehensive evaluation of water-resource availability, refine water-use estimates, and characterize aquatic ecology and streamflows needed to support selected...
Oklahoma FloodWatch
By combining the historical record, data from ongoing streamgage monitoring, and data on new events, the USGS is able to develop the expertise and tools that help Federal, State, and local community leaders not only to enhance short-term preparation, aid, and recovery efforts, but to better understand how their flood risk may be changing over time and how they can reduce their risk in future...

Oklahoma DroughtWatch
The U.S. Geological Survey Oklahoma Water Science Center continuously monitors the status of surface water in the State's principal rivers, reservoirs, and aquifers. Selected index stations with long-term continuous record spanning many drought periods are used to compare existing streamflows, reservoir storage, and ground-water levels with normal and extreme recorded values. These comparisons...
Oklahoma StreamStats
The U.S. Geological Survey (USGS) periodically publishes streamflow statistics, such as flood-frequency, flow-duration, and mean annual streamflow statistics, for gaged sites with long-term record. Regionalized regression methods recently have been developed for estimating many of these streamflow statistics at ungaged sites as a function of measured physical and climatic drainage basin...
Streamflow gains and losses in the Colorado River in northwestern Burnet and southeastern San Saba Counties, Texas
In October 2012, the U.S. Geological Survey (USGS), in cooperation with the Central Texas Groundwater Conservation District, began an assessment to better understand if and where groundwater from the Ellenburger-San Saba aquifer is discharging to the Colorado River, and if and where Colorado River streamflow is recharging the Ellenburger-San Saba...

Sediment and nutrient trapping as a result of a temporary Mississippi River floodplain restoration: The Morganza Spillway during the 2011 Mississippi River Flood
The 2011 Mississippi River Flood resulted in the opening of the Morganza Spillway for the second time since its construction in 1954 releasing 7.6 km3 of water through agricultural and forested lands in the Morganza Floodway and into the Atchafalaya River Basin. This volume, released over 54 days, represented 5.5% of the Mississippi...

Water-level altitudes 2015 and water-level changes in the Chicot, Evangeline, and Jasper aquifers and compaction 1973-2014 in the Chicot and Evangeline aquifers, Houston-Galveston region, Texas
Most of the land-surface subsidence in the Houston-Galveston region, Texas, has occurred as a direct result of groundwater withdrawals for municipal supply, commercial and industrial use, and irrigation that depressured and dewatered the Chicot and Evangeline aquifers, thereby causing compaction of the aquifer sediments, mostly in the fine-grained...

Simulation of groundwater flow and chloride transport in the “1,200-foot” sand with scenarios to mitigate saltwater migration in the “2,000-foot” sand in the Baton Rouge area, Louisiana
Groundwater withdrawals have caused saltwater to encroach into freshwater-bearing aquifers beneath Baton Rouge, Louisiana. The 10 aquifers beneath the Baton Rouge area, which includes East and West Baton Rouge Parishes, Pointe Coupee Parish, and East and West Feliciana Parishes, provided about 184.3 million gallons per day (Mgal/d) for public...
