The Watershed Boundary Dataset (WBD) is a comprehensive aggregated collection of hydrologic unit data consistent with the national criteria for delineation and resolution. It defines the areal extent of surface water drainage to a point except in coastal or lake front areas where there could be multiple outlets as stated by the "Federal Standards and Procedures for the National Watershed Boundary Dataset (WBD)" "Standard" (https://pubs.usgs.gov/tm/11/a3/). Watershed boundaries are determined solely upon science-based hydrologic principles, not favoring any administrative boundaries or special projects, nor particular program or agency. This dataset represents the hydrologic unit boundaries to the 12-digit (6th level)...

The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water...

An extensive archive, estimated to contain more than 3,500 historical (1925–2020) geophysical logs collected in conjunction with past studies conducted by various entities, and more than 2,000 additional donated well and geophysical logs are stored in hard-copy at the Central Texas Branch of the Oklahoma-Texas Water Science Center (OTWSC) located in Austin, Texas. This dataset addresses the need to preserve these records electronically by providing a scanned and indexed collection of 6,058 of these records in Portable Document Format (PDF) along with a public Microsoft Access database and comma-separated values (CSV) text file containing detailed well header information for each record.
