Water Supply Reserve Account – Grant Application Form Form Revised May 200 7 _______________________________________ numerous occasions. It is knowledgeable and familiar with the rock weirs and J - hook structures proposed here, developed by D.L. Rosgen, P.H. of Pagosa Sprin gs, and has used them on the river for several years. Tabor: There are no Tabor issues as the applicant entity is a 501(c ) (12) entity. Scope of Work 5 . Please summarize the proposed scope of work. Please refer to Part 2 of the Criteria and G ui dance document for detailed requirements. On the following p age there is an example format for the Scope of Work . You can use the example format or your own format, provided that comparable information is included. The scope of work should outline by ta sk how the water activity will be accomplished. It is important that the scope of work detail the specific steps, activities / procedures that will be followed to accomplish the water activity and the specific products/deliverables that will be accomplished . The scope of work should include but not be limited to: task description, key personnel, budget, schedule and deliverables and the final report/project documentation upon completion of the water activity . I . Task Overview of task: The Romero - Guada lupe Channel Rectification Project requests $83,700 from the SB179 Rio Grande Basin Account in order to fund the re - shaping of the channel of the Conejos River at the project location (described below and in attached maps ) and the placing of rock water con trol structures as designed by the NRCS. NRCS has done the accompanying engineering and the drawings based on acceptable procedures for the installation of rock weirs and J - hooks . A copy of the NRCS work plan and engineering drawings for the Romero Irrigat ion Company are attached in Appendix A. Also attached is the Conservatin Plan Map for Guadalupe Main Ditch portion of the task , which NRCS has completed sufficiently enough to d etermine the scope of work and costs for this proposal. Final details for the Guadalupe drawings are close to completion as of this writing and we anticipate forwarding them to support this application in July. Method / Procedure to accomplish the task As described in the enclosed “Plans for the Construction of Conejos River Di version & Streambank Protection”, t he tasks for the placement of W - weir rock structures and J - hooks will follow standard accepted procedures and will conform to NRCS specifications . Ditch company supervision and consultation will be provided at one quarter time over six months, ensuring that these specifications are met. W - Weir rock structures: The design of the W - Weir (W as looking in the downstream direction) will be installed to resemble bedrock control channels on larger rivers , avoiding the unnatura l and uniform “line of rocks” that detracts from visual values. The W - Weir is similar to a Cross - Vane in that both sides are vanes directed from the bankfull bank upstream toward the bed with similar departure angles. From the bed at ¼ and ¾ channel width, the crest of the weir rises in the downstream direction to the center of the bankfull channel creating two thalwegs ( see Figure 5 , in Rosgen’s description, attached ). The objectives of the structure are to provid e grade control , enhance fish habitat, stab ilize stream banks , facilitate irrigation diversions, and incre ase sediment transport . Habitat for trout is enhanced by maximizing usable holding, feeding and spawning areas. Fish hold in the multiple feeding lanes created by the two thalweg 10
