City Of Lafayette

TZA developed a raw water supply operational model to assist the City in planning for its acquisition of water rights and storage facilities. The model can simulate the operations of various direct flow and storage rights which divert from South Boulder and Boulder Creeks, as well as alternative operating scenarios for raw water storage facilities. The raw water supply model has been used to determine the firm (dry year) yield which can be derived from the City’s existing water rights portfolio, to evaluate the increased yield which may be obtained from purchase of various additional water rights, to evaluate the benefits of alternative modes of reservoir operation, and to quantify the amount of raw water storage needed to optimize the firm yield of various water right portfolios.
