The Standing Rock Tribe relies on an intake along the Oahe Reservoir to supply drinking water to their communities. The Oahe Reservoir now is down 32 feet...This reservoir is being managed under rules that were written 50 years ago...This is all overwhelmingly managed for the benefit of the barge industry downstream. Because when they started this process they thought the barge industry was going to be a much more dominant economic player. That proved to be wrong. Things changed. Transportation systems changed. The management of the reservoirs has not changed. The Corps of Engineers regulate the six dams on the mainstem of the Missouri River and they were extraordinarily hard headed on the issues of dealing with the water in the entire Missouri River system. The upper reaches of that system have been systematically cheated in the manner in which that river has been managed.
