River/Stream Flow Application Information
The Texas River Guide River/Stream Flow Application utilizes United States Geological Survey (USGS) Real-time Water Data located at http://water.usgs.gov/tx/nwis/current/?type=flow.
Gage information listed on this site includes river/stream gages and a limited number of spring gages (when spring flow levels directly effect river conditions).
Reservoir/Lake gages are not included at this time.
Flow data for Texas Rivers/Streams is downloaded from the USGS website to a Texas Parks Wildlife server and placed into a format which allows end users to view USGS data via a spatial format.
This application calls the USGS server and updates on the Texas River Guide every 30 minutes.
End users must refresh their screens periodically in order to obtain the most current USGS River/Stream flow information.
Texas Parks Wildlife Department (TPWD) accepts no responsibility for the accuracy of the data provided on this site.
Non-TPWD sources, such as USGS and other cooperating entities, generate this data.
River users should always use common sense, observe river safety techniques, and consider conditions they find at the waterway.
Select the desired river/coastal basin by clicking on the basin name on the legend to the left or by clicking directly on the basin on the Texas map on the right.
When the desired river/coastal basin is displayed, move your cursor over the desired gage either on the legend (right) or the yellow dots on the basin map (left). The gage information will appear in a box located directly underneath the basin map.
To print specific gage information click on the desired gage to freeze the browser. Click again to resume normal operation.
