<br />September 15, 2004 <br /> <br />Lower Arkansas River Basin <br />District 10 <br />Diversion Structure Inventory <br /> <br />1 West Pueblo Ditch <br /> <br />Narrative of Structure Components and Repair Plan <br /> <br />The West Pueblo Ditch structure appears to be an intake for a pump station. This <br />structure is located approximately 80 feet downstream of the diversion point, or at the <br />upstream end of the ditch. The intake consists of a concrete structure with a <br />prefabricated steel enclosure on top. An 8-foot-wide by 8-foot-high screen is mounted <br />within an opening in the upstream concrete wall of the intake. The gate(s) were not <br />visible, as well as the remaining structure components. It appears water is being <br />conveyed from the intake approximately 300 feet north to a pump station. <br /> <br />Approximately 200 feet upstream of the diversion point, and approximately 1 ,200 feet <br />downstream of the Pueblo Reservoir Dam, there is a dam that spans the river. The dam <br />consists of a series of placed boulders, and appears to be designed to help divert flow to <br />the ditch. The banks of the ditch are lined with both natural rock formations and placed <br />boulders. <br /> <br />There is another structure of unknown name approximately 120 feet downstream (east) <br />of the intake structure. The structure consists of a concrete headwall that was <br />constructed between two natural rock formations, and has a 4-foot-wide steel vertical lift <br />headgate. Steel railroad T-rails span the top of the structure. Approximately 50 feet <br />downstream of the structure, possible remnants of the original structure remain. <br />Continuing downstream another 35 feet, is the beginning of a 100-foot-long concrete- <br />lined trapezoidal ditch. The ditch conveys flow through a CMP culvert beneath Juniper <br />Road, then continues east. <br /> <br />The overall condition of the intake structure appears to be good. No repairs have been <br />noted for the visible portions of the structure. The condition of the unknown structure <br />also appears to be good, but decking and handrail should be installed for access and <br />maintenance. A trash rack should also be installed upstream, to help keep debris from <br />collecting in front of the headgate. <br /> <br />Summary of Recommended Repairs <br /> <br />Diversion (unknown name) <br />o Install decking and handrail <br />o Install trash rack <br /> <br />Estimated Ranae of Cost <br /> <br />Low: $0 - $250,000 <br /> <br />Farnsworth Group <br />
