2021 Palmdale Ditch Conversion Feasibility Study
The 2021 report is a feasibility study to determine if 7.2 miles of the earthen and concrete-lined Palmdale Ditch can be converted to a pipeline system. Once completed, the project will provide the following benefits – Increase flow capacity from 25 cubic feet per second (cfs) to 60 cfs, reduce seepage and evapotranspiration losses, and mitigate downstream flooding that occurs when Littlerock Dam is spilling. The purpose of the study is to perform hydraulics analysis and pipe sizing to convey 60 cfs from Littlerock Dam to Lake Palmdale, complete a pipe materials evaluation and recommend a material selection, evaluate water loss savings, develop feasibility level cost estimates for construction, and prioritize ditch sections for replacement.
