This website is a product of the Texas Water Development Board - TWDB - Surface Water Resources Division and is made possible by the support of management and staff at TWDB. This project is part of their ongoing efforts to synthesize and communicate water-related data to scientists, policy makers and the public. Currently, only Texas historical and current reservoir data are available through this website. In the future, they will be adding other data sets including data related to drought, groundwater, and bays and estuaries. TWDB is charged by the Texas Legislature with measuring and calculating flows in streams and to conduct studies, investigations, and surveys of the occurrence, quantity, quality and availability of surface water in Texas.
To accomplish these objectives, the TWDB partners with several data providers to obtain and verify water-related data, including historical data that is not available online. In particular, they would like to acknowledge the following data providers - United States Geological Survey - USGS. International Boundary Water Commission - IBWC. United States Army Corps of Engineers - USACE. United States Bureau of Reclamation - USBR. Lower Colorado River Authority - LCRA. TWDB Hydrographic Survey Program
