However, construction of the Gunnison Tunnel some <br />50 years ago permitted the importation of a supplemental supply from the <br />Upper Gunnison subbasin, which has augmented the natural supplies of the <br />Uncompahgre subbasin. Taylor Park Reservoir, with a storage capacity of 106,200 <br />acre-feet in the Upper Gunnison subbasin, has provided streamflow regulation in <br />recent years which has made the combined supply adequate for the irrigation <br />of the Uncompahgre project lands. <br /> <br />!here are additional areas of irrigated lands within the subbasin which are so <br />situated that they cannot obtain water from the supplemental supplies, or, in <br />some cases, from the Uncompahgre River or its Larger and more dependable <br />tr.ibutarieS. !hese areas have instead been furnished with water supplies of <br />varying degrees of adequacy, by several smaller locally constructed projects. <br />Among the larger of these has been the Cimarron Ditch, which has imported wa,ter <br />from the Cimarron River in the Upper Gunnison subbasin for use on Bostwi.ck and <br />Shinn Parks and in the town of Montrose. Additional developments have been <br />nade at Tierra Colorado, Log Hill Mesa, Dallas Creek, and other locations. In <br />most caSeS, the available supplies have been less than requirements and in a <br />few instances only token water supplies are available to some of the lands. <br /> <br />Project operat:ions result in extensive return flow accretions to the streams of <br />the subbasin. These essentially constitute a part of the overall water re- <br />source, since .they are frequently iediverted by canals in lower parts of the <br />subbasin. They have not been included in the water-supply tabulations, however, <br />since they originate in the measured or estimated inflows and inclusion 'would <br />result in .duplipation of a part of the subbasin water-supply resource. <br /> <br />Total undepleted water supply of the subbasin is summarized in table 29. <br />- 76 - <br />
