be blocked so any local storm water flows will need to be pumped over the levee by the community or drainage district responsible for local storm water management. The USIBWC has moved into Flood Fight Operations. During this phase of response, crews work 24 hours per day to patrol flood control levees to identify and respond to any problems that could arise such as erosion along the levees, freeboard encroachment, or seepage on the land side of the levees.
At the Commission’s uppermost reservoir, Amistad Dam, located at Del Rio, Texas-Ciudad Acuña, Coahuila, flood releases continue at the rate of 35,000 cubic feet per second (1000 cubic meters per second). Releases were initiated July 5 and were increased to the current rate on July 6. This is the greatest release of water from Amistad Dam since 1974.
Emergency Operations Centers at USIBWC Headquarters in El Paso, Texas and the Lower Rio Grande Flood Control Project Office in Mercedes, Texas were established last week to provide round-the-clock response and coordination with the Mexican Section of the Commission.
The Commission is managing its flood control infrastructure taking into account prudent operation of the reservoirs, existing flood conditions in parts of the Rio Grande and its tributaries in the United States and Mexico, impact to property, and forecasts for additional rainfall in the basin, including additional tropical weather impacts.
Information about Rio Grande flow as well as storage and release data from U.S. and Mexican reservoirs in the Rio Grande basin is available on the USIBWC web page at:
