Guadalupe River Flooding of July, 2002

Excessive rainfall in the Guadalupe River Basin led to flash flooding and eventually major river flooding along the lower Guadalupe River Basin.

While the most devastating flooding along the Guadalupe River was in the San Antonio and New Braunfels area, major flooding also occurred in the Victoria area. Beginning Monday afternoon July 1, the Guadalupe River began to slowly rise from approximately 8 feet to 10 feet by early Tuesday morning July 2. The river rose more sharply and reached flood stage (21 feet) over the next 24 hours.

During the next eight days, the river rose gradually reaching 30.36 feet in Victoria on Wednesday July 10 at 8pm. At the Dupont plant in Bloomington, flooding occurred in a similar manner. Flooding was mainly confined to the southwest side of Victoria including Riverside Park, low roadways along Highway 59, and the flood plain from Victoria south to the San Antonio River Confluence.

At the early stages of the event, the NWS Corpus Christi received hundreds of phone calls from concerned citizens along the Guadalupe River. Many were significantly impacted by the floods of 1998. How does this flood compare with the record floods of 1998?

The graph on the left depicts the preliminary unofficial river reading from the gauge in Victoria from July 1-15, 2002. The blue line is the actual measurement of the river in feet. The colored lines depict the collection of forecasts issued by the National Weather Service West Gulf River Forecast Center in Fort Worth, Texas. River forecasts were updated every 12 hours during the event, and more frequently during the height of the flood. Also during the flood, Victoria gauge readings were confirmed by our backup gauge the the CPL plant in South Victoria.

The graph on the right shows the all time record flood events for the Guadalupe River at Victoria. As you can see when viewing the actual amount of water flowing down the Guadalupe River, the flood of July 2002 pales in comparison to the flood of August 1998. During the height of the July 2002 flood, over 60,000 cubic feet of water was measured flowing past the gauge per second (cfs). During the height of the August 1998 flood, the flow was measured at nearly one-half a million cfs.
