During the summer of 2008, monsoon rainfall filled reservoirs across northern Mexico. In late August 2008, releases out of La Boquilla, Frank Madera, and Luis Leon Reservoirs were increased to lower water levels in those reservoirs. By mid-September the Rio Grande and it's people were experiencing record flooding. This page is dedicated to those people and that event to record what went right, learn what went wrong, and what can be done in the future to prepare for the next one.
