Instream Flow Improvement Project Summary

MVID CulvertProject Goals:

  • Increase instream flows in the Twisp River below the MVID West Canal diversion.
  • Prevent mortality of listed fish species and reduce habitat impacts at MVID’s Twisp River point of diversion.
  • Allow for future habitat improvements at the MVID point of diversion.
  • Provide a reliable water supply to foster continuing agriculture in the Methow Valley.

 Project Objectives:

  • Improve instream flow in the flow–impaired lower 4.5 miles of Twisp River by adding 11 CFS.
  • Develop an improved, reliable, and low maintenance system for MVID water users.
  • Avoid increased assessment charges to the MVID and its members as a direct result of this Project.
  • Prevent fish injury and mortality associated with MVID’s Twisp River pushup dam, fish screen operations, and the stranding of redds and juveniles in the MVID West Canal’s intake canal and fish return channel.
  • Eliminate the low-flow passage barrier associated with MVID’s pushup dam.

Current Scope, Updated Aug 13, 2014:

  • Project Description
  • Current Project Budget, Approximately $10 million
  • Estimated Date Entire New System Will be Fully Functional May 1, 2016.

Initial Project Assumptions and Constraints:

  • The Project will change the MVID West Canal’s 11 cfs point of diversion from the Twisp River to the Methow River
  • New system MUST be operational by May 1, 2015
  • System performance, initial trouble shooting will be monitored and adjusted during summer of 2015
  • MVID assumes full ownership and responsibility for the system after a negotiated break-in period.
  • All alternatives will result in an economically viable system
  • Funding commitment is for both MVID East and West
  • East Canal Projects will be administered by MVID (including Survey/Design/Construction)
  • A Formal change process will be implemented after 30% design
  • MVID retains responsibility for abandoned canals and laterals.
  • Regardless of the selected alternative – Users/Landowners above Twisp will be converted to individual wells
  • All MVID West main canal and laterals as part of the Project will need to be replaced, with the exception of the portions piped by MVID in the summer of 2012
  • The piping construction must take place outside of irrigation season.  This construction season is also constrained by winter conditions such as snow depths greater than 3’ and temperatures lower than 10 degrees F.
  • WDFW Screen Dept will financially support and assist with screen removal
  • The system will be designed for a 11 CFS Max instantaneous flow rate
