Little Weber River Cutoff Channel (Weber County)

Emergency Watershed Protection:  Little Weber River Cutoff Channel (Weber County)

Project Description

The Natural Resources Conservation Service (NRCS) and Weber County have analyzed alternatives to reduce flood impacts to the land surrounding the lower Weber River during elevated flows in the river. The lower Weber River flowing through western Weber County, Utah does not have sufficient capacity to convey flood flows to provide protection to the surrounding agricultural and residential areas. The Little Weber River Cutoff Channel is a historic floodplain channel in western Weber County that has routinely carried flood flows to the Great Salt Lake in the past, but is currently disconnected from the Weber River due to agricultural activities, construction of roads and dikes, and residential development. This channel was activated during the 2011 flood event and numerous breaches were intentionally created in roads and embankments to convey water through this historic channel.

NEPA Analysis

This project is being partially funded by the NRCS Emergency Watershed Protection (EWP) program to reduce potential impacts from future flood events directly affecting the Weber River. A National Environmental Policy Act (NEPA) Programmatic Environmental Impact Statement (EIS) was prepared by NRCS for the EWP program; however, this project does not fit within the analysis parameters of the Programmatic EIS. NRCS, as the lead federal agency, has initiatied an 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.

Current Status

The Draft Environmental Assessment Public Comment Period Closed on Friday August 16, 2013.  NRCS compiled comments received and have completed the Final Environmental Assessment for the project.  The NRCS Utah State Conservationist has decided that a Finding of No Significant Impact is approved for the proposed alternative (Little Weber River Cutoff Channel - North Diversion).

According to NRCS NEPA regulations, a 15-day public review period will be opened for the project since it is located in a wetland and floodplain.  The public review period will end on March 21, 2014.
