The <br />reservoir is fed by either the Highline Canal or the Juniata Canal, while the <br />flow line originates at the City Intake structure, located just upstream of the <br />canal headgates. Water stored in Juniata Reservoir is released downstream into <br />Purdy Mesa Reservoir which outlets into the Purdy Mesa Reservoir flow line. <br />Neither reservoir interconnects with the Kannah Creek flow line. <br /> <br />2.2 PURPOSE OF STUDY <br /> <br />The system's primary deficiency is that North Fork water cannot be adequately <br />stored for subsequent municipal usage. With the purchase of the Anderson Ranch <br />in 1955, the City became the sole owner of all water rights in the North Fork <br />basin, including snowmelt intercepted by the B,A & J Oitch (see Figure 2-1). <br />Traditionally, this water has been used mainly for irrigation purposes via <br />divers ion to Reeder Reservoi r through the Laurent and Bauer 0 itches. Reeder <br />Reservoir is not connected to either flow line, and does not therefore <br />contribute to the City's raw water supply system. <br /> <br />Up to 6 cfs of North Fork water can be diverted to Purdy Mesa Reservoir via the <br /> <br /> <br />City Ditch, but can only flow through the reservoir and cannot be stored, as <br /> <br /> <br />further discussed in Chapter 3. <br /> <br />Because of these system limitations, the City of Grand Junction entered into an <br />agreement with HDR Infrastructure, Inc. in July of 1985 to develop a <br />recommended plan and cost estimates for each of the following project <br />components: <br /> <br />2-4 <br />
