Water Resources of Texas

Water information is gathered by the USGS Texas Water Science Center to minimize the loss of life and property from natural disasters, to contribute to the conservation and sound economic and physical development of the Nation's natural resources, and to enhance the quality of life by monitoring water, biological, energy, and mineral resources.

The USGS provides real-time stream stage and stream flow, water quality, and groundwater levels for more than 650 sites in Texas, including these newly installed continuously monitored sites.

Texas Water Dashboard

View over 750 USGS real-time stream, lake, reservoir, precipitation, and groundwater stations in context with current weather and hazard conditions. Two fully-autonomous Twitter feeds distribute water level and precipitation data during flooding or severe rainfall: @USGS_TexasFlood and @USGS_TexasRain.

Streamflow and Springflow at Comal and San Marcos Rivers

Spring Lake, San Marcos TX

Understanding the amount of springflow at these Springs is critical for local water resource managers. However, springflow cannot always be measured directly at Comal or San Marcos springs.

Instead, springflow is calculated by USGS staff from the measured streamflow values, and both daily springflow values and streamflow measurements are posted online.

The data is presented with new interactive data graphs which let you view the past 1,000 days of springflow and streamflow at Comal Springs and San Marcos springs.
