'"'c\ <br />:,... ~ ,J <br /> <br />MANNER OF MAKING THE STUDIES <br /> <br />21 <br /> <br />originally proposed Chotfield reservoir site which was authorized <br />to be constructed by the Corps of Engineers as a flood control <br />reservoir, there being also an arrangement whereby some of its <br />capacity could have been used for conservation and some of the <br />capacity of Two Forks as flood control, is now occupied largely by <br />the Martin Plant, Included in the City's present program is the <br />construction of a high diversion dam at Strontia Springs, the <br />purpose of which is to divert water through a tunnel to the pro- <br />posed new Roxsborough filter plant. Although this dam could be <br />constructed to a height which would back water up to the tail- <br />water of a power plant at Two Forks Reservoir, nevertheless the <br />afterbay storage provided by such a development would be far <br />short of that requi red to permit the use of a power plant at Two <br />Forks Reservoir for peaking purposes, <br /> <br />The October 1955 decree referred to earlier imposes on the <br />City of Denver (and Colorado Springs) the obligation of replacing <br />electric energy which otherwise could be generated at the Govern- <br />ment's Green Mountain power plant had it not been for diversions <br />from the Blue River by the two municipalities, The decree specifies <br />that such electric energy shall be delivered to the United States <br />at substantially the same rates ond approximately the same hours <br />the energy could have otherwise been generated at the Green <br />Mountain plant. The extent to which this obligation can be ful- <br />filled through the operation of the 3000-kilowatt power plant now <br />under construction as a feature of the Willioms Fork Dam Project <br />was determined. <br /> <br />All of the Williams Fork plant capacity ultimately will be <br />required to replace a portion of such power that otherwise could <br />be generated at Green Mountain Reservoir by water which Denver <br />will divert from the Blue River, Studies were also made of the <br />amount of commercial power that could be generated at the Wil- <br />liams Fork plant during the interim period preceding the time <br />when all of its capacity will be required for replacement of power. <br />It was assumed that the commercial power would be generated at <br />a load factor equivalent to the system load factor of the Publ ic <br />Service Company of Colorado, This would permit its being more <br />readily comprehended into the Public Service Company's system, <br />assuming that the U,S, Bureau of Reclamation would wheel the <br />
