Missouri is taking action to stop the US Army Corps of Engineers from changing how it manages the Missouri River. Attorney General Jay Nixon says the Corps is in violation of the Flood Control Act passed by Congress in the 1940s, because it is placing the concerns of upstream interests ahead of those downstream through one phrase “adaptive management.” A spokesman for the Corps says it is simply trying to balance what often are conflicting laws. The new legal action filed by the Attorney General is one of seven new lawsuits filed since the Corps released its new Missouri River Master Manual.
