Project Description:
Since the completion of Mansfield Dam (then the Marshall Ford Dam) in1941, the 100 year floodplain for Lake Travis has been recognized as 716 feet asl. However, a recent Corps of Engineer study in 2003 revealed that an elevation of 722 feet asl would be more accurate. The goal of this project was to create a new 100 year floodplain map for Lake Travis. Not only will this data be important for predicting floods, but changing the elevation of the floodplain means that hundreds of people that were outside the "danger zone" will now be within and will be required to purchase flood insurance under the National Flood Insurance Reform Act of 1994 if they have not done so already.
