Except, Chairman Smith, Cannonball River is away from the pipeline route. Only place where Cannonball River meet the pipeline is where the pipeline meet Lake Oahe. And that area have already been clear of all sites. However to note, Indians sites are everywhere. Your house probably sit on one and that won't be too surprising.  That website show the entire length of Cannonball River.....99% of it on land not even related to the pipeline issue. It still doesn't deter the fact that Northern Borders Pipeline across over the water while Dakota planned to go under it. One pipeline is there already....another one is being built right next to it and that is the issue?? These Sioux and their white lapdogs should have been protesting this back in 1983!!
