<br />I <br /> <br />I <br /> <br />The water users have an active replacement program, but it takes a long <br />time to replace the features. I would like to show you just a few of <br />the things that the water users have been doing to improve their system. <br />Here we see the Selig DiversiDn Dam from another view before it was <br />rebuilt; and this is the way it looks now. <br /> <br />Here we see the Loutzenhizer Canal headworks before and after; the twin <br />flumes over Happy Canyon Creek before and after; small wooden flumes <br />have been replaced by more modern concrete flumes. Another feature <br />replaced by the Association is the Montrose-Delta Diversion Dam on the <br />Uncompahgre River south of Montrose. <br /> <br />Siphons have also been replaced. Some of the siphons and flumes and <br />tunnels that are still existing are small and limit the water available <br />to the project lands. These bottlenecks create special management prob- <br />lems to the irrigators. Other reaches of the canals are at full capacity <br />and need enlargement. <br /> <br />One item that adds to the high operation and maintenance costs is the <br />miles and miles of laterals required to serve project lands, particularly <br />to the east of the Uncompahgre River. Some canals traverse miles and <br />miles of nonarable lands before reaching the irrigable lands that they <br />serve. Even on some of the more level areas, extensive lateral systems <br />are necessary to serve the scattered irrigable lands. <br /> <br />Seepage losses from canals and laterals are estimated at close to thirty <br />percent. The major losses occur as the canals move from the floodplains <br />up the river onto terraces, and they have to traverse these gravel areas <br />near the points where they go onto the terraces. As a result of the <br />seepage that occurs in these areas, many acres Df land are unproductive. <br />Associated with these seepage losses is the accumulation of saline salts. <br />In some areas, almost entire fields have become unproductive because of <br />salt buildup. <br /> <br />Another concern to irrigators is the erosion caused by canals and laterals <br />crossing s,hale hills. These eroded areas make it difficult to maintain <br />turnouts and divert the water from the deep gullies and channels that <br />are created. <br /> <br />Another concern that's been expressed through our public meetings is <br />that when Taylor Park Reservoir was constructed, it created a unique <br />fishery in the Taylor River below the dam and in the reservoir itself. <br />Thousands of fishermen and recreationists use this reservoir each year, <br />but the Uncompahgre water users are the ones that pay the entire cost. <br /> <br />In the early, studies of the improvement program, two types of water <br />needs were identified -- water from storage within the area and water <br />savings through system improvements such as lining canals and replacing <br />worn out wood structures. One storage site investigated was the Coal <br />Creek site shown here, but with the purchase of water from the Dallas <br />Creek project, the storage needs have essentially been met. The water <br />users only concern now is ways of improving the system and removing <br />bottlenecks. <br /> <br />-9- <br />
