The St. Louis District hosted the annual River Resource Action Team boat trip Aug. 17 – 19 on the Middle Mississippi River within the St. Louis District. The RRAT is the St. Louis District's coordination forum to discuss environmental issues, compliance and share lessons learned with the District’s partners and stakeholders. The group traveled on the Corps of Engineer's Pathfinder from downtown St. Louis to the mouth of the Ohio River near Cairo, Ill. The trip has taken place each year since the early 70s, after the passage of groundbreaking environmental laws, such as the Clean Water Act and the Endangered Species Act.
