Summary: Tropical Storm Harvey moved back inland and further east
Tropical Storm Harvey moved off shore yesterday and has made landfall again in southeast Texas. The areas of rainfall are now located in basins east of Houston and into Louisiana. The four day rain totals in the Houston area were at least 30 inches in most of the area and exceeded 50 inches in some areas of south and along the coast. It is expected to take many days and even weeks for flood waters to recede from the extensive areas that are affected.
The Colorado and Brazos basins have reached peak flow in the areas upstream toward Austin and are nearing peak flows at the most downstream sites. The San Jacinto and Trinity basins further east are still rising. Buffalo Bayou through downtown Houston is still in major flood stage. As of this morning, the gates on the Addicks and Barker reservoirs remained open.
USGS crews made 14 measurements, repaired several gages, and installed one RDG downstream of Barker Reservoir. Today, 15 crews are out to do repairs and make measurements in the Brazos, Colorado, Guadalupe, and Trinity Rivers and repair any gages that they are able to reach. About 11 gages were not reporting this morning. Some of them have started reporting again as the high water recedes and the sensors resume a working range to the surface. Crews also continue to provide support for the Addicks and Barker reservoir operation with measurements today downstream of Barker Reservoir at stations on Buffalo Bayou. In addition to the RDG installed downstream of Barker, two gages at the reservoirs were repaired yesterday and raised to give them greater elevation from the current water level.
Communication with the USACE, NWS, the State Operation Center, and cooperators has been frequent as they ask for assistance or information and to ensure that we are providing the most important support.
