The TWDB monitors water conditions throughout the state. Reports are created monthly for selected groundwater wells, reservoirs, and streamflow sites.
TWDB numbered reports include a variety of surfacewater and groundwater themes, published from 1965 to present.
Groundwater bulletins typically present results of long-term or extensive investigations, often covering a large region or county. Topics include well records, geology, and groundwater resource information, but are not limited to groundwater themes. This series was published from 1950 to 1965.
Historic TWDB groundwater reports contain records of wells, driller's logs, water analyses, and maps. This series was published from 1936 to 1961.
Researchers and Texas water history buffs may be interested in the online USGS water supply paper series. Prepared by the U.S. Geological Survey, some in collaboration with the Texas Board of Water Engineers & later with the TWDB, this collection includes papers spanning almost a hundred years: from 1898 to 1988.
