Experts Find U.S. Army Corps of Engineers' Flood Management Needs Improvement

Flood Gate "In 2011 the mainstem Missouri River Reservoir System experienced the largest volume of flood waters since the initiation of record-keeping in the nineteenth century. The high levels of runoff from both snowpack and rainfall stressed the System’s capacity to control flood waters and caused massive damage and disruption along the river." "As part of post-flood assessment efforts, the U.S. Army Corps of Engineers, Northwestern Division, enlisted the assistance of experts in meteorology, hydrology, streamflow forecasting and reservoir system operations to review, analyze and assess the Corps' operation of the six mainstem dams along the Missouri River leading up to, and during, the Flood of 2011." The independent review is outlined in the report: Review of the Regulation of the Missouri River Mainstem Reservoir System During the Flood of 2011. "In conducting the review of the Missouri River mainstem reservoir system during the 2011 flood, the review panel divided its findings into two areas: • Conclusions regarding regulation of the reservoir system by the Corps during 2011 for the authorized purpose of flood control. The conclusions are summarized as answers to a set of questions that served as the starting point of the review process. The original questions posed by the Corps were supplemented by additional questions that arose during the panel investigation. • Recommendations for actions to prevent or reduce damages from similar, or larger floods in the future."
