Green River/Tusher Diversion Dam Rehabilitation (Utah Deptof Ag & Food)

Emergency Watershed Protection:  Green River/Tusher Diversion Dam Rehabilitation (Utah Department of Agriculture and Food)
 

Project Description

Green_River_Diversion_RehabThe Green River/Tusher Diversion was constructed in the early 1900s and has been modified over the years to maintain the structure.  During the 2010/2011 flood events, flows in the Green River caused severe damage to the diversion structure, compromising its structural integrity.  In the event of diversion failure, water service to three irrigation canals, the City of Green River, a historic irrigation water delivery system, and one hydropower plant would be eliminated.  Rehabilitating the diversion would directly result in these resources remaining usable for the water rights holders.  The NRCS and UDAF have analyzed alternatives to maintain the existing functions of the diversion for water delivery to irrigation canals and upgrade the diversion structure to current design standards, as well as provide upstream and downstream fish passage and tracking, fish screening, enhanced sediment sluicing, and downstream recreational boat passage. The fish protection and passage components are proposed for inclusion in the project to meet Endangered Species Act requirements for listed fish species populations in the Green River.  The boat passage provision is a navigability requirement of the state of Utah.
 

Project Proponents

  • The Natural Resources Conservation Service (NRCS) - Lead Federal Agency
  • Bureau of Land Management (BLM) – Public Lands Management, Cooperating Agency
  • United States Fish and Wildlife Service (USFWS) - Endangered Species Act Technical Oversight
  • State of Utah Forestry, Fire and State Lands (FFSL) – State Sovereign Lands
  • Utah State Historic Preservation Office (SHPO) - National Historic Preservation Act Consultation
  • Utah Department of Agriculture and Food (UDAF) – Local Sponsor


NEPA Analysis

This project is being partially funded by the NRCS Emergency Watershed Protection (EWP) program to restore the damage from the 2010/2011 flood events and stabilize the structure. A National Environmental Policy Act (NEPA) Programmatic Environmental Impact Statement (EIS), was prepared by NRCS for the EWP program; however, the repair of this diversion structure does not fit within the analysis parameters of the Programmatic EIS. NRCS, as the lead federal agency, is initiating additional NEPA analysis in the form of an Environmental Assessment to analyze impacts to the natural and human environment from this project. The Environmental Assessment will comply with the Council on Environmental Quality’s regulations at 40 CFR Parts 1500-1508 which require an evaluation of potential environmental impacts associated with federal projects and actions.


Project Alternatives

Two Action Alternatives have been carried forward by NRCS and the project team to be analyzed in detailed study for this DEIS: the Replace In Place Alternative and the Replace In Place With Passages Alternative.  In accordance with NEPA, the No Action Alternative must also be analyzed.

Next Phase

The Draft Environmental Impact Statement (DEIS) Public Comment Period is currently open (open comment period: March 14, 2014 – April 30, 2014).  NRCS will compile all comments received and complete the Final Environmental Impact Statement for the project.  The DEIS presents a No Action Alternative and two Action Alternatives: the Replace In Place Alternative and the Replace In Place With Passages Alternative.
