Flood Forecasting

The National Weather Service is mandated to provide river flood forecasts for the nation. Forecasts on the Guadalupe River are handled by the NWS River Forecast Center in Fort Worth, Texas. You can obtain the latest river forecasts at the River Forecast Center website at www.srh.noaa.gov/wgrfc.

FEMA Flood Insurance

GBRA encourages homeowners along rivers and creeks to purchase Flood Insurance through the Federal Insurance Program. You can visit their website at www.floodsmart.gov/floodsmart/.

Flood Information

No matter where you live, it pays to be aware of flood hazards. Floods are one of the most common, and most costly, disaster events in the United States and can occur even outside of existing floodways and flood plains. Below you will find links to information sources to help protect yourself, your family, and your property during flood events in the Guadalupe River basin.

  • GBRA "Staying Safe" Flood Guide - a comprehensive manual explaining historic flood events, floodplains, the GBRA Hydro Lakes and their operation, a planning checklist, flood forecast points, radio station access information for the Guadalupe basin, flood insurance, and additional resources.
  • KWED 1580 AM - provides the latest information about local flooding in Guadalupe County, provided by GBRA and local emergency management officials, and can broadcast even during a power outage using its emergency generator.
  • Follow GBRA on Twitter - we will issue up-to-date information during flood events using this service. NOTE: this service is used for emergency purposes only.
  • Federal Emergency Management Agency (FEMA) - for information about all programs offered by this agency.
  • Turn Around Don't Drown - is a NOAA National Weather Service campaign to warn people of the hazards of walking or driving a vehicle through flood waters.

Flood Preparedness (Hydroelectric Lakes)

In cooperation with local authorities, media and lake management groups, GBRA has developed materials to provide local residents, including those along Lakes Dunlap, McQueeney, Placid and Meadow, with valuable information during a flood event.

The Interim Flood Preparedness Plan explains what happens in the event of local flooding, and includes maps, definitions and rainfall patterns. The Plan can be downloaded using the link above, or is available by contacting GBRA at 830-379-5822.

In the event of a flood watch or warning, GBRA will provide information to KWED Radio about current river flows and their effect on GBRA hydro lakes, from New Braunfels to Seguin. Lake residents and others who may be affected by local flooding should refer to the appropriate Flood Tracking Chart for their area.

These charts, which can be downloaded above or obtained from GBRA, allow the user to graphically relate the current flood flows at Lakes Dunlap, McQueeney, Placid and Meadow to historic and comparable conditions, lake levels, track current events and plan for an evacuation, if necessary.

We encourage you to listen to KWED 1580 AM at these times for the latest flood reports and evacuation plans.

If you have specific questions or need additional information about how to use these charts, please contact David Welsch or Tommy Hill at GBRA at 830-379-5822.
