Blacktail Creek is about 15 miles north of Williston.
Glatt says it doesn't make sense to try to collect the small amount of contaminated water that is overflowing the dams along with the fresh water. He says he doesn't think it will have a bigger impact downstream.
The saltwater is an unwanted oil-production byproduct that is considered an environmental hazard.
Crews will be working in others areas until they can resume collecting the contaminated water.
