<br />o <br />C) <br />(;',J <br />CJ <br /> <br />-'-, <br /> <br />CHAPTER V <br /> <br />STAGE TWO PLAN OF DEVELOPMENT <br /> <br />freeboard of 6 inches. <br /> <br />Existing structures such as drops, road cross- <br /> <br />ings, parshall flumes, and turnouts (including canal headgates) would be <br /> <br />retained if structurally and hydraulically sound. Structures not needed <br /> <br />would be removed. The laterals would generally not be fenced; however, <br /> <br />any existing fence would be replaced after construction. <br /> <br />The lateral <br /> <br />systems are explained below and summarized in Table 6. <br /> <br />Government Highline Canal Laterals <br /> <br />The Government Highline Canal laterals are categorized according to <br /> <br />the east end, middle, and west end canal segments. <br /> <br />East end Government Highline laterals .--The 32 east end Government <br /> <br />Highline laterals are diverted from a 10-mile section of the Government <br /> <br />Highline Canal extending from Palisade to Grand Junction. These laterals <br /> <br />have a total length of 25 miles and initial capacities ranging from 1 to <br /> <br />13 cfs. These are private development laterals and serve lands of both <br /> <br />the Palisade and Mesa County Irrigation Districts. <br /> <br />Middle Government Highline laterals.--The middle Government Highline <br /> <br />laterals consist of 54 laterals diverted from a 20-mile section of the <br /> <br />Government Highline Canal extending from Grand Junction to the Stage One <br /> <br />area. The laterals have a total length of 83 miles and initial capaci- <br /> <br />ties ranging from 1 to 34 cfs. <br /> <br />All of the middle Government Highline <br /> <br />laterals are federally developed and are operated and maintained by the <br /> <br />Grand Valley Water Users Association. <br /> <br />West end Government Highline Laterals .--The 10 west end Government <br /> <br />Highline laterals are diverted from the last lO miles of the canal. The <br /> <br />laterals have a total length of 36 miles and initial capacities ranging <br /> <br />from 3 to 40 cfs. These are also federally developed laterals. <br /> <br />37 <br />
