Characterization of streamflow, suspended sediment, and nutrients entering Galveston Bay from the Trinity River, Texas, May 2014–December 2015
The U.S. Geological Survey (USGS), in cooperation with the Texas Water Development Board and the Galveston Bay Estuary Program, collected streamflow and water-quality data at USGS streamflow-gaging stations in the lower Trinity River watershed from May 2014 to December 2015 to characterize and improve the current understanding of the quantity and quality of freshwater inflow entering Galveston Bay

Simulation of the effects of different inflows on hydrologic conditions in Lake Houston with a three-dimensional hydrodynamic model, Houston, Texas, 2009–10
Lake Houston, an important water resource for the Houston, Texas, area, receives inflows from seven major tributaries that compose the San Jacinto River Basin upstream from the reservoir. The effects of different inflows from the watersheds drained by these tributaries on the residence time of water in Lake Houston and closely associated physical and chemical properties including lake elevation, s

Methods for estimating concentrations and loads of selected constituents in tributaries to Lake Houston near Houston, Texas
Since December 2005, the U.S. Geological Survey, in cooperation with the City of Houston, Texas, has been assessing the quality of the water flowing into Lake Houston. Continuous in-stream water-quality monitors measured streamflow and other physical water quality properties at stations in Spring Creek near Spring, Tex., and East Fork San Jacinto River near New Caney, Tex. Additionally, discrete w

Regression model development and computational procedures to support estimation of real-time concentrations and loads of selected constituents in two tributaries to Lake Houston near Houston, Texas, 2005-9
In December 2005, the U.S. Geological Survey (USGS), in cooperation with the City of Houston, Texas, began collecting discrete water-quality samples for nutrients, total organic carbon, bacteria (Escherichia coli and total coliform), atrazine, and suspended sediment at two USGS streamflow-gaging stations that represent watersheds contributing to Lake Houston (08068500 Spring Creek near Spring, Tex

Evaluating the variability of sediment and nutrient loading from riverine systems into Texas estuaries and bays
The water quality in estuaries and bays and the health of these coastal ecosystems are affected by sediment and nutrient loads transported by streams. Large sediment loads delivered to an estuary or bay can degrade water quality. Concentrations of suspended sediment are affected by natural conditions (such as soil erosion and streambed resuspension) and can also be affected by human activities (su

A preliminary evaluation of Trinity river sediment and nutrient loads into Galveston Bay, Texas, during two periods of high flow
Suspend-sediment and water-quality data were measured during two periods of high flow, one during April 20-23, 2009 and a second during September 22-November 3, 2009. On the basis of streamflow and continuous and discrete water-quality measurements, the two periods of high flow had different flood and nutrient loading characteristics. Some differences in the nature of these two periods of high flo

Gulf Coast Ecosystem Restoration Council Monitoring and Assessment Program Development
The National Oceanic and Atmospheric Administration (NOAA) and USGS will jointly lead the development of foundational components for Gulf region-wide monitoring.
Sediment Acoustics
The U.S. Geological Survey recognizes the need to provide sediment acoustic training and to develop standardized techniques and practices.
Water Quality Monitoring at Offshore Artificial Reefs
USGS Texas Water Science Center scientists are collecting physical and chemical water properties at selected Texas artificial reefs to provide the initial foundation to establish the status and long-term trends in the environment and information essential for sound management decisions and long-term planning.
RESTORE Act Activities in Texas
The USGS is collaborating with NOAA to develop tools to aid in an implementation strategy for integrated monitoring that will enable the RESTORE Council to meet its reporting requirements to Congress as well as to achieve the Councils goals, objectives, commitments and mission of science-based comprehensive Gulf ecosystem restoration.
Nutrient and Sediment Monitoring in Inflows to Texas Bays and Estuaries
The USGS Oklahoma-Texas Water Science Center is evaluating the variability of nutrient and sediment concentrations and loads entering Texas bays and estuaries across a range of hydrologic conditions in Galveston Bay (inflow from the Trinity and San Jacinto Rivers), Matagordo Bay (inflow from the Colorado River), San Antonio Bay (inflow from the Guadalupe River), and Nueces Bay (inflow from Nueces...
Assimilative Capacity of Lake Livingston
The nutrient and sediment data collected by this study provides insight into assimilative capacity of reservoirs and impacts to inflows for coastal Texas.
Sediment Science in Oklahoma and Texas
The U.S. Environmental Protection Agency (EPA) has identified sediment as a leading cause of impairment in the Nation’s rivers and streams. Excessive sedimentation degrades aquatic habitat; reduces longevity of water-supply, flood-control reservoirs; and is the primary transport mechanism of toxic organic chemicals, heavy metals, and nutrients. The USGS Oklahoma-Texas Water Science Center (OTWSC)...
Coastal Science in Texas
Coastal science at the USGS Oklahoma-Texas Water Science Center (OTWSC) includes groundwater, surface water, and water-quality studies. Surface water includes coastal waters, estuaries, and major inflows to the coast. Visit the links below for more information on our data and science.
