The US Army Corps of Engineers releases a new master manual for management of the Missouri River. It has taken nearly 15 years to put together the document, and it is not without its controversial sections. Two of the most controversial provisions allow for man-made spring floods known as a spring rise and reduced amounts of water released from upstream dams during the driest parts of the summer. Officials with the Corps of Engineers point out the new master manual is in closer compliance with the Endangered Species Act.
