Non-USGS Sources of Hydrologic Data

International Boundary and Water Commission (IBWC)

The IBWC is a joint United States/Mexican authority responsible for the management and oversight of the Rio Grande River Basin. The IBWC provides access to PROVISIONAL flow data on the Rio Grande River, updated on a regular basis on its Web site at: http://www.ibwc.gov/Water_Data/rio_grande_WF.html#Stream

Lower Colorado River Authority (LCRA)

The LCRA is a conservation and reclamation district that has six dams on the lower Colorado River. They help in flood control and serve as a water supply for municipal, industrial, agricultural and recreational users throughout a 10-county area. This area includes Blanco, Burnet, Llano, Travis, Bastrop, Fayette, Colorado, Wharton, San Saba and Matagorda counties. The LCRA posts a discussion of current conditions in its Daily River Report at:
http://www.lcra.org/water/conditions/river_report.html
PROVISIONAL flow and lake stage data in the Upper and Lower basin at:
http://www.lcra.org/water/conditions/index.html
In addition to the flow and lake data, the LCRA also provides a weather discussion/forecast page at:
http://www.lcra.org/water/conditions/weather/index.html

National Weather Service (NWS)

The mission of the NWS is "To provide weather and flood warnings, public forecasts and advisories for all of the United States, its territories, adjacent waters and ocean areas, primarily for the protection of life and property." The NWS provides internet access to selected hydrologic data collected by the USGS and other agencies in Texas via the Interactive Weather Information Network (IWIN). Some stations are not available from the USGS Current Conditions pages, including stage data along the Rio Grande and a few other good boating rivers, and reservoir elevations and release data.
