Real-time water-quality, streamflow and water height information for Lake Houston and the surrounding San Jacinto watershed are now available from a new web application from the U.S. Geological Survey, done in cooperation with the City of Houston.
Lake Houston is the primary drinking-water source for Houston, Texas. Real-time data are required to evaluate the effects of watershed influences, such as land-use change and storm events, on Lake Houston water quality. These data will help water treatment facility operators make informed decisions about adjusting treatment methods in response to changing water-quality conditions.
Real-time measurements are updated hourly and visualizations are accessible from 40 USGS observation stations, which collect a combination of lake, stream, groundwater well, precipitation and water-quality data. The map viewer includes supporting data layers, such as current and forecasted weather conditions and hazard warnings. Users can view seven real-time water-quality observation stations: four located on streams that flow into, and three within, Lake Houston. The continuous water-quality monitoring stations are located in urbanized and rural parts of the watershed and measure various parameters such as turbidity, pH and others.
