<br />There are other measuring devices available such as weirs and flumes of different <br /> <br /> <br />designs. However, we feel for the money which will be spent, they are either <br /> <br />not as accurate, more difficult to maintain, more costly to build or have not <br /> <br />been widely field tested, and therefore, should not be considered. Approximate <br /> <br /> <br />costs of these measuring devices are shown as follows: <br /> <br />Metering gates - $1,500 <br />Parshall Flumes - $2,500 <br /> <br />'This is an installed price based on <br />,a measuring device capable of carrying <br />five (5) to six (6) c.f.s. <br /> <br />These prices include the measuring device and installation. We recommend that <br /> <br />whichever device is used that there be one ,device for each irrigated field ir- <br /> <br /> <br />respective of who owns the stock. This should be a standard practice through- <br /> <br /> <br />out the system. The primary reason is thaG individual records can be maintained <br /> <br />for each field. There are cases now where a shareholder has two (2) or more out- <br /> <br />lets from the ditch at the same location which supply water to different fields. <br /> <br /> <br />It may seem desirable to consolidate the flows to a single device, however, <br /> <br />problems could arise if the present shareholder should decide to sell his property. <br /> <br /> <br />It it becomes advantageous to have only one outlet for two (2) or three (3) fields, <br /> <br /> <br />the water should immediately enter a distribution box and then flow through in- <br /> <br />dividual meters before letting the water proceed to the fields. Any time a new <br /> <br />shareholder is allowed to take water from the ditch and a turnout is not provided <br /> <br />along with that change in ownership, it is recommended that the new shareholder <br /> <br />be required to pay for an additional gate for his own use and have it installed <br /> <br /> <br />by the ditch company or a representative thereof. <br /> <br />Check Structures: <br /> <br />Each stockholder is provided water through a measuring gate as shown in the <br /> <br /> <br />previous section. The elevation E1 is obtained by adjusting the check structures <br /> <br />along the ditch. The check strucutres along this ditch are all made of concrete, <br /> <br /> <br />The water in the ditch is checked, or raised in elevation by placing wooden <br /> <br />planks across the width of the ditch, thus raising the weir height. When the <br /> <br />water is raised enough to deliver the flow needed through a metering gate; checking <br /> <br /> <br />is halted. <br /> <br />17 <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br />
