Planning meeting at the USGS Gulf Coast Office.

USGS field crews made multiple record high flood measurements on Aug. 27, including downstream of Addicks and Barker dam. Flood measurements near Addicks and Barker dam are critical for making public safety decisions, as 1.2 million people live downstream.
