Threat: Improper sediment management
At risk: Sustainability of community, economy, and river environment
The Niobrara River is an oasis for paddlers, anglers, and wildlife. A major tributary of the Missouri River, the lower portion of the Niobrara is protected under a federal Wild and Scenic River designation. At its confluence with the Missouri, the Niobrara is increasingly threatened by too much sediment backing up behind the Missouri River’s Gavins Point Dam.The sediment is raising the level of the Niobrara and threatening local communities with flooding. The U.S. Army Corps of Engineers must improve sediment management within the Missouri River system and must prioritize funding for this critical issue in their Fiscal Year 2015 budget.
