Floodwater to recede around Houston by Saturday
HOUSTON - Officials say flood waters are expected to be gone from most of Houston and Harris County by late Friday or early Saturday.
Jeff Lindner, meteorologist for the Harris County Flood Control District, said Harvey flooded an estimated 136,000 structures in Harris County, or 10 percent of all structures in the county database. He called that a conservative estimate.
Lindner said 70 percent of the county's land mass, or about 1300 square miles, was submerged by at least 1½ feet of water. The heaviest rainfall recorded in Harris County was 47.4 inches on Clear Creek at Interstate 45 in the southeastern part of the county, near the NASA Johnson Space Center.
He said there has been a very slight fall in the waters of Buffalo Bayou, which flows past downtown Houston into the Houston Ship Channel, but flood waters remain in the residential areas on the margins of the Addicks and Barker reservoirs that control flooding on Buffalo Bayou and the Houston Ship Channel. Col. Lars Zetterstrom, commander of the Galveston District of the U.S. Army Corps of Engineers, says they remain full but that their water pools have lowered very slightly.
Zindner said the reservoirs will take three months to fully drain after 35 to 40 inches of rain fell on their watershed.
Zetterstrom says that the Addicks and Barker dams are withstanding their load well.
