<br />released via the Roberts Tunnel into the upper reach of the North Fork at Grant. <br />Traditionally~ Dillon Reservoir water has been used to supplement Cheesman releases. <br />As more people move into Denver Water's service area, more Dillon Reservoir water, via <br />the Roberts Tunnel, may be used. <br /> <br />Dillon Reservoir is an important recreation facility for fishing and boatingt Its operations <br />also affect the fishery and whitewater recreation on the Blue River below the reservoir. <br /> <br />In order to safely transport Dillon Reservoir water, the carrying capacity of the North <br />Fork has been increased from the Roberts Tunnel to Insmont. Flow easement agreements <br />and channel capacity limits the use of the tunnel during high flow. Practice has been to <br />not add flow if it would cause the Grant gage to exceed 680 cfs for extended periods. <br />Recently the channel work has been designed to enhance structural fish habitat. No large <br />diversions are made on the North Fork. Depending on weather and water supply <br />conditions, Dillon Reservoir water is imported through the Roberts Tunnel all year, none <br />of the year, or one month and not the next. Because it has traditionally been the <br />supplemental supply, water imported from Dillon Reservoir can vary as lawn watering <br />increases or decreases in Denver. <br /> <br />The Roberts Tunnel has a 5~5 megawatt power plant that produces an average annual <br />revenue of $500,000. In order to receive the capacity payment, a minimal amount of <br />energy must be produced each month the generator is in operation~ Where possible, water <br />deliveries are scheduled in order to obtain the capacity payment. <br /> <br />N :\Supply\ W aage\wi Idscen\attachb.doc <br /> <br />B-36 <br />
