Groundwater flow and storage in the Edwards and Trinity aquifers are largely controlled by the geologic structure and hydrostratigraphy in the region. To help local agencies and stakeholders to more effectively manage the regional water resources, a better understanding of the spatial distribution of the geologic framework and hydrostratigraphic units of the aquifers is needed.

In cooperation with the City of Houston, USGS collects, processes, and interprets water-quality, streamflow, and reservoir water elevation and capacity data. These data are collected to better understand the effects of urbanization in Lake Houston, a drinking water reservoir in Houston, Texas.

GWWebFlow is a browser-based groundwater model viewer designed to allow users to easily explore model inputs and outputs for published and approved USGS models.

The USGS Earth Resources Observation and Science (EROS) Center Science Processing Architecture (ESPA) On-Demand Interface is used to request processing and services for Landsat Science Products.

This tool produces shapefiles that contain the delineated basins, basin characteristics, and flow statistics for multiple sites requested at once by users. Before this tool can be used, the the points of interest will likely need to be edited in GIS so that they are coincident with the stream grid used by StreamStats for delineations and saved to a shapefile.

The StreamStats application uses data web services that were created for it. When in use, the application manages interactions between the user and the services. However, the web services can be directly accessed using the StreamStats Service API documented here or consumed by a custom client application using HTTP protocols.

The Water On-the-Go app has been discontinued. You can view gages near your location using the National Water Dashboard. “Water On-the-Go” was a map-based web application to give people easy access to current conditions in streams across Texas. It was developed to help raise water awareness during floods and normal conditions.

The Whole Wildlife Toxicology Catalog is a compilation of websites containing toxicological information related to amphibians, reptiles, birds and mammals that may be of value to scientists, risk assessors, regulators and natural resource managers.

The Coastal National Elevation Database (CoNED) Project Viewer is a portal to the topobathymetric models created with the expertise of the expertise of the U.S. Geological Survey Earth Resources Observation and Science (EROS) Center near Sioux Falls, SD.

The Health-Based Screening Levels for Evaluating Water-Quality Data searchable online database provides Health-Based Screening Levels (HBSLs) for hundreds of chemicals, including pesticides and degradates. HBSLs are non-enforceable benchmark concentrations of contaminants in water. These screening levels supplement federal drinking-water standards and guidelines.
