 Two boys died when the SUV they were riding in crashed and ended up on its side in a marsh along Interstate 94 west of Jamestown. Stutsman County Sheriff Chad Kayser. We figured about five acres of slough right at the interstate. That slough kind of connects to other ones in that area. We got a lot of local support and called in a bunch of people that had big pumps, and we were actually pumping off the slough to try and get the water down.
