A study to develop an earth observation monitoring system to detect harmful algal bloom (HABs) presence within selected north Texas reservoirs using satellite imagery was conducted by the U.S. Geological Survey (USGS). This data release provides the data collected for this study including site locations, water-quality, phytoplankton, and hyperspectral water surface reflectance data. Data were collected between September of 2019 and December of 2020 at 39 sites distributed across 16 reservoirs and 1 stream. The stream site was sampled in response to an algal bloom in August of 2019 in Austin Tex., and is included herein but the reservoir sites are the focus of this data release. The datasets include all routine and...
This data release includes aerial imagery collected during two uncrewed aerial system (UAS) imagery surveys at an edge-of-field site north of Medina River Natural Area near San Antonio, Texas, on August 14, 2019, and July 8, 2022. A total of 1,153 images were collected during the survey on August 14, 2019, and a total of 1,277 images were collected during the survey on July 8, 2022. In total, 2,430 images provided in the form of geotagged true-color aerial images in JPG format are provided.
This data release includes ground control points (GCPs) collected during two uncrewed aerial system (UAS) imagery surveys conducted at an edge-of-field site north of Medina River Natural Area near San Antonio, Texas, on August 14, 2019, and July 8, 2022. Ten GCPs were used on each survey date, and a total of twenty GCPs are described in this data release.
This data release includes two digital orthomosaic images produced from uncrewed aerial system (UAS) imagery surveys conducted on August 14, 2019, and July 8, 2022 at an edge-of-field site north of Medina River Natural Area near San Antonio, Texas. These images were compiled from sets of aerial imagery included in this data release. Orthomosaic images can be used for visual reference but do not contain elevation data.

Bathymetric data for a near-shore area of the Laguna Madre near South Padre Island, Texas, July 2021
The U.S. Geological Survey, in cooperation with the City of South Padre Island, Texas, collected baseline bathymetric data for a near-shore area of the Laguna Madre near South Padre Island in July 2021. Bathymetric survey points were collected using real-time kinematic Global Navigation Satellite System (RTK-GNSS) equipment. The data included in this data release are presented in a comma-separated values (csv) file format.

A previously completed mineral resources assessment of the Texas Coastal Plain indicated the potential for future discovery of uranium resources. Composite hydrogeologic frameworks can be used in geoenvironmental assessments as a tool to understand potential effects of mining operations. Data for a composite hydrogeologic framework are documented in this data release. The hydrogeologic framework focused on the composite hydrogeologic unit consisting of the upper part of the Miocene-age Fleming Formation/Lagarto Clay, Pliocene-age Goliad and Pleistocene-age Willis Sands, Pleistocene-age Lissie and Beaumont Formations, and Holocene-age alluvial sediments (fluvial alluvium and eolian sand deposits). This composite...

In September 2022, the U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, collected groundwater-level elevation data and water-quality samples from monitoring wells at the Many Diversified Interests, Inc. Superfund Site in Houston, Texas to evaluate the status of groundwater contamination at this previously remediated site. The dataset includes groundwater-level elevations and field properties measured at 12 monitoring wells along with data from environmental and quality assurance and quality control water-quality samples collected at each well. Water-quality samples were analyzed for arsenic, manganese, molybdenum, benzo(a)pyrene, and petroleum hydrocarbons.

The U.S. Geological Survey, in cooperation with the City of South Padre Island, Texas, collected base line hydrodynamic (tidal water level and current velocity) data for a near-shore area of the Laguna Madre near South Padre Island from August 18, 2021, to April 27, 2022. The data included in this data release are presented in a comma-separated values (csv) file format.

This data release includes two dense point clouds produced from uncrewed aerial system (UAS) imagery surveys conducted on August 14, 2019, and July 8, 2022 at an edge-of-field site north of Medina River Natural Area near San Antonio, Texas. The dense point cloud for the August 14, 2019, survey contains 166,261,373 points, and the dense point cloud for the July 8, 2022 survey contains 164,395,847 points. Points within the dense point cloud have not been classified.
Arundo donax (Arundo Cane) is an invasive perennial reed that can grow more than 30 feet tall and has become established in riparian zones along rivers throughout the southwestern United States. It grows in thick stands, readily displaces native riparian habitat, and provides no habitat or food for native species in the ecosystems it disrupts (McWilliams, 2004). The Texas State Soil and Water Conservation Board (TSSWCB) has been directed to develop and implement a program to eradicate Arundo Cane along the entire 1,255 mile length of the Rio Grande in Texas (Texas Senate Bill 1734). The TSSWCB has been using an ecosystem-based approach that integrates the use of biological, chemical, mechanical, and cultural controls...
Uncrewed aerial system (UAS) flights were conducted by the U.S. Geological Survey at an edge-of-field site located north of Medina River Natural Area near San Antonio, Texas on August 14, 2019, and July 8, 2022, to support efforts aimed at estimating edge-of-field erosion and potential sediment loading into the Medina River near San Antonio. Data provided here include imagery obtained during the flights, and ground control point (GCP) information. Additional products including automatically generated point clouds, digital surface models (DSMs), and orthomosaic imagery produced using structure-from-motion (SfM) techniques are part of this data release.
Hydrophobic (sediment-associated) pesticides were measured in sediment samples collected from 82 wadeable streams and in biofilm in 54 of those streams in the Central California Foothills and Coastal Mountains ecoregion.115 current-use and 3 legacy pesticides were measured in stream sediment; 93 of the current-use pesticides and the same 3 legacy pesticides were measured in biofilm. On average 4 times as many current-use pesticides were detected in biofilm at a site (median of 2) as in sediment (median of 0.5). This data release provides data for the pesticide concentrations, information on the pesticide compounds, and input data and R scripts for statistical models used in the analysis presented in the journal...

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.
