Document Description
The purpose of the project is to repair vital ranch infrastructure that delivers irrigation and stock water from the property owner's adjudicated water right on Shackleford Creek. The applicant will repair and reinstall the existing irrigation pipeline across Mill Creek. The project design is similar to the existing design, but will extend the length of the pipeline to offer more lateral movement of the channel of Mill Creek and minimize the accumulation of river-run sediment. Project implementation will involve repositioning two existing 40-ft long 24-in diameter steel pipes and then extending the pipeline by installing two additional pipes. The repaired pipeline will be 160 ft long and will be supported by two 4.5-ft tall steel cradles. The majority of additional pipeline length will be placed within Shackleford Ditch and not within Mill Creek. In addition to extending the pipeline length, the project will also grade the streambed at the project site to allow unrestricted flow under the pipeline and to relocate the thalweg away from the river-left bank where Shackleford Ditch meets Mill Creek. An excavator, crawler tractor, and backhoe will access the project site using an existing road. Heavy equipment will grade river-run gravels, cobbles, and boulders, pushing the recently deposited material to the adjacent stream banks. An excavator with a thumb attachment will reposition existing large boulders from within the channel to reinforce thestream bank on the north side of Mill Creek. Grading will occur approx. 100 ft upstream and 100 ft downstream of the pipeline, to a depth to provide a min of 4.5 ft of clearance under pipeline and sufficient cross-section area for high flow events. The proposed project design will provide approx. 20% more free-spanning length over Mill Creek. Approx 2,900 cy ofmaterial will be graded and relocated at the project site. All grading will match the up and downstream gradient. No sediment will be placed or removed from Mill Creek, and no riparian vegetation will be removed to complete the proposed project. All work will be conducted when Mill Creek is dry.
