Note.-Decrease in White River is relatively large because of diversion of 150,000 acre-feet to Yampa Basin. FUTURE IRRIGATION POSSIBCLITIES. As stated, rather extensive systems can be built covering large acreages, and these have been outlined by surveys. Probably most of the possibilities have been covered. Water supply available at the point of diversion is not always sufficient for the total acreage included in the different projects by the surveys, and in the list following only the acreage is given which can be supplied in most years. The estimates 01 water- supply are deduced, in some cases where discharge measurements are lacking, from run-off of adjacent related drainage areas, which is not a reliable basis.
