The Standing Rock Rural Water System

The Standing Rock Rural Water System is a $30 million water system funded by the American Recovery and Reinvestment Act in 2009 for about 10,000 residents of the Standing Rock Sioux reservation in North Dakota. The RWS includes the Standing Rock Water Treatment and the "Indian Memorial Intake Pump Station, a raw water pipeline, two transmission pipelines and Kline Butte Storage Reservoir." The main regulation reservoir of the Standing Rock Rural Water System is the $3.6 million Kline Butte Storage Reservoir, located southwest of Kenel, South Dakota, which consists of a 5 million gallon ground storage reservoir. Currently, the intake valve for the water system is "located in a shallow part of the Missouri River near Fort Yates, North Dakota, roughly 20 miles from the planned river crossing of the controversial Dakota Access Pipeline also known as the Bakken pipeline. The Bakken oil pipeline Dakota line is to be "buried 92 feet below the riverbed in hard clay." A new valve came online in 2016 in Mobridge, South Dakota which is seventy miles south of the proposed Bakken Pipeline Missouri River crossing. This Mobridge intake valve is intended to service the entire Standing Rock Sioux reservation.
"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."
