Ditch company reservoirs are generally <br />operated in aggregate with storage water moved between and among storage units in <br />order to maximize efficiency of available supplies. <br />Ground Water Rights <br />Ground water wells are not used for irrigation purposes within the Left Hand Ditch Company <br />service area. <br />Transbasin Water <br />The ditch company is within the boundaries of the Northern Colorado Water Conservancy <br />District (NCWCD). C-BT water can be delivered to the ditch company via the Boulder Feeder <br />Canal directly or by exchange, dependent on the location of the ditch headgates receiving the <br />water, as shown in Figure 2. The ditch company currently uses about 3,900 C-BT units for <br />irrigation purposes. <br />Left Hand Ditch Operating Memorandum.doc 13 of 17 January 5, 2005 <br />
