A 25-foot section of inland underwater oil barrier is laid out on a dock prior to deployment, Monday, April 23, 2018, in Kalamazoo, Mich. The three-foot high barrier is made of PVC and X-Tex fabric, and is designed to let water flow through while trapping oil. Weighted chains and scour flaps prevent oil and sediment from flowing underneath the barrier. (U.S. Coast Guard Photo courtesy of Research and Development Center)
