The BBC has a story on the need to dump water from a dam in Mississippi on the Tangipahoa River because the structure was damaged by the storm and may collapse if the pressure isn’t released.

This has required Louisiana officials to begin evacuating people downstream because of the flooding that will result from the release.

This type of problem is occurring in several places because local flood control measures [dams and levees] are being stressed by the storm surge and the rain runoff.

On the plus side, the rains will ameliorate the drought conditions and fill lakes and reservoirs that are running dry, but it won’t end the drought unless the weather pattern changes and the normal rains return.
