Welcome to the TACA Website. I am truly honored to serve as the 2016 - 2017 President of the Tax Assessor-Collectors Association of Texas. Ronnie Keister - TACA President. Lubbock County Tax Assessor-Collector.
A flood is caused by a combination of heavy rainfall. causing river / oceans to over flow their banks, and can. happen at any time of the year, not just in the winter. Floods generally develop over a period of. days, when there is too much rainwater to fit. in the rivers and water spreads over the land.
When the discharge of a river increases, the channel may become completely full. Any discharge above this level will result in the river overflowing its banks and causing a flood. The stage at which the river will overflow its banks is called bankfull stage or flood stage. For example, the flood stage of the Mississippi River at New Orleans is 17 feet. Discharge that produces a stage over 17 feet will result in the water nearing the top of the levee with potential flooding of the city of New Orleans (the top of the levee is actually at 25 feet above sea level).
