<br />At the Pueblo dam site the river transports about
<br />944 acre,feet of sediment per year. Approximately 42 per
<br />cent of that is deposited in reservoirs, canals and laterals;
<br />about 38 per cent becomes. undesired deposition on the
<br />irrigated lands. Filling in of the river channel has made
<br />some irrigation diversion structures inoperative. The only
<br />apparent immediate solution is provision .of reservoir space
<br />specifically for the disposition of sediment.
<br />Ben F. Powell, Bureau of Reclamation engineer at
<br />Pueblo, has estimated that at the end of 100 years sedi,
<br />ment deposition at the Pueblo dam site could be expected
<br />to be 15 feet above the present stream bed elevation.
<br />Storage capacity in the reservoir of 94,400 acre-feet is
<br />provided in the Bureau plan for sedimentation.
<br />Of the 944 acre,feet of mud which would enter the
<br />Pueblo reservoir annually, it is estimated that the reser-
<br />voir would prevent 75 I acre,feet of sediment from being
<br />deposited in existing reservoirs, canals, laterals and on
<br />irrigated lands.
<br />
<br />FLOOD CONTROL BENEFITS CITED
<br />
<br />Provision of 93,OOOacre,feet capacity in the reser,
<br />voir for flood control would offer a remedy for the
<br />$890,000 average ,annual damage which is caused by
<br />floods in the river between the Pueblo dam site and the
<br />John Martin reservoir, constructed by the Army Engi'
<br />neers.
<br />Colorado's valuable assets in scenety and recreational
<br />opportunities, including fish and game resources, are
<br />amply protected in the Bureau's plan for development of
<br />the region thru cooperation with the Fish and Wildlife
<br />service and National Park service.
<br />Recreation, including the tourist industty, is a real
<br />and valuable asset to Colorado, even though its develop-
<br />ment in Colorado may be considered incomplete, it is one
<br />of the top sources of business income.
<br />The Western slope has developed important recrea'
<br />tionalareas at Aspen, Grand Mesa, Glenwood Springs,
<br />Gunnison and at other places.
<br />Both slopes of the Continental Divide-with their
<br />majestic scenety including heavily forested areas, high
<br />mountains and many streams-are potential recreational
<br />areas with almost unlimited possibilities. The National
<br />Park service is cooperating with the Bureau of Reclama-
<br />tion in studies of the recreational aspects of the area,
<br />and its recommendations will be followed to the fullest
<br />possible extent.
<br />Studies are also being made by the Fish and Wild-
<br />life service to determine the minimum flow need for the
<br />preservation of fishing, which is a summer sport of con-
<br />siderable financial significance in the diversion area and
<br />in the uprer Arkansas valley.
<br />Loca project representatives of the Water Develop,
<br />ment Association emphasize the potential benefits of the
<br />project to fishing and recreational interests in Western
