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.
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 scope...

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...
Aquifer Characteristics of Selected Aquifers in Oklahoma
Digital geospatial data sets of aquifer characteristics have been produced from existing, published paper reports for major aquifers in Oklahoma. The aquifer characteristics compiled include hydraulic conductivity, recharge, water-level elevation, and aquifer boundaries.The individual aquifer characteristic data sets are designed especially for use with Geographic Information Systems (GIS) for...
