Chatfield Reservoir Reallocation Project An innovative, multipurpose, sustainable water resource project to benefit Colorado, the Chatfield Reallocation Project reallocates 20,600 acre-feet of water in a U.S. Army Corps of Engineers-managed dam for renewable water sourcing. The project provides a blueprint for future regional reallocation projects. Created in 1975 for flood control and water storage, Chatfield Dam and Chatfield State Park draws 1.6 million visitors annually while providing water supply for Denver and the Front Range. With a metro population expected to double over the next 40 years, area water providers are challenged to meet growing water needs of communities and farmland while reducing demand on depleted groundwater supplies. Redeveloping the public facilities displaced by raising the operating water level 12 feet was a monumental feat of engineering and construction. This required moving 14 sites and 1.4 million cubic yards of soil — the equivalent of burying a football field 787 feet deep — across 500 acres. Throughout the two-year construction period, the team kept the park open, limited disruptions, and maintained the park’s $2 million annual revenue. To satisfy reservoir volume maintenance requirements, each yard of material placed was matched by a yard removed at the same elevation elsewhere. Planning and design under these constraints, and adjacent to a large body of water, required unique modelling, structural, and geotechnical approaches and solutions. Completed on schedule and on budget, the $171 million Chatfield Reservoir Reallocation Project provides generations of Coloradoans, municipalities and agriculture additional water supply at less cost, disruption and environmental impact than a new reservoir.

Section One S Ection O Ne
Section One Waterton Canyon to County Line Road Recreation districts in charge: Douglas County Parks, Trails & Buildings Grounds Metro District of Highlands Ranch Parks and Open Space General Information The segment from Waterton Canyon past Chatfield Reservoir is rural in nature and passes over both private property and Chatfield State Park land. Some 50,000 people annually use this section of the path. Akin to a sandy, country road, the trail here is difficult for road bikes but well suited for horseback Section One riders, mountain bikers, hikers and nature lovers, who will see an abundance of wildlife. The extraordinary design and construction of the canal is evident throughout this segment. The High Line begins nearly two miles up the canyon at a diversion dam on the South Platte River that funnels the water into a 600-foot- long tunnel. The water is siphoned beneath the river at one point and carried in aqueducts (or flumes) around several gulches before it emerges into the high plains, where the trail beings. 6 • Length: 16 miles across two major segments that are not connected. • Access: Wadsworth Boulevard (Colo. 121) and South Platte Canyon Road (Colo. 75) lead south to the Kassler Center, site of Denver Water’s old Kassler Water Treatment Plant. Trailhead parking is available in lots at the nearby Discovery Pavilion and at the Waterton Canyon parking lot. Cross the bridge over the South Platte to get to the trail. • Regulations: Campfires, dogs, unauthorized motorized vehicles, swimming and boating are not allowed in Waterton Canyon. Hours are half-hour before sunrise to half-hour after sunset.

CONCLUSIONS AND RECOMMENDATIONS I have carefully reviewed the water supply problems and the proposed solutions in the Denver Metro area documented in this Chatfield Reservoir Storage Reallocation Feasibility Report/Environmental Impact Statement. This report was prepared by the Omaha District U.S. Army Corps of Engineers and the non-federal partner, Colorado Water Conservation Board of the Colorado Department of Natural Resources (CDNR), in conjunction with the 12 water providers which have requested storage reallocation for water supply in Chatfield Reservoir. Population growth has resulted in increased municipal and industrial (M&I) water demands and some water providers have relied on nonrenewable Denver Basin groundwater. Various alternatives to meet water supply needs were examined in this report. These alternatives were evaluated for environmental, social, cultural, and economic impacts, as well as engineering feasibility. The alternatives also were judged against national and local planning objectives. The planning process included extensive coordination with a wide range of potentially affected/interested parties, including federal, state, and local government agencies.

Chatfield Lake, Jefferson and Douglas Counties, Nebraska
STATEMENT OF FINDINGS CHATFIELD LAKE, COLORADO 1. I have reviewed and evaluated, in light of the overall public interest, the relative information concerning the actions remaining on the authorized project, as veil as the stated views of other interested agencies and the concerned public relative to these remaining actions and their effect along the South Platte River including the Denver metropolitan area. My review also considered all of the impacts discussed in the Final Environmental State ment, some of which are specifically referenced in succeeding paragraphs. A supplemental environmental statement will be pre pared for the downstream channel portion of the project extending from Chatfield Lake to Denver when a plan of flood protection is recommended for that reach of the South Platte River. At the time of submission of the final supplemental environmental state ment, a supplemental Statement of Findings will also be prepared. 2. The possible consequences of the various alternatives have been studied according to environmental, social well-being, and economic effects, including regional and national development and engineering feasibility. The various elements considered include those identified in Section 122 of Public Law 91-611 and the Conference Report on H.R. 9270, 92d Congress. 3. In evaluating the alternatives, the following points were con sidered pertinent: a. Authorization and current project status. (1) The Flood Control Act of 1950 authorized construction of Chatfield Dam and Lake and channel improvements along portions of the South Platte River from the dam downstream to Fort Morgan. The Chatfield portion of the project was funded for construction following the flood of record which occurred in June 1965.

New Chatfield Reservoir Reallocation Project Website Launched
New Chatfield Reservoir Reallocation Project website launched April 14, 2015 FOR MORE INFORMATION: David Howlett or Marge Price 303-433-1804 The Chatfield Reservoir Reallocation Project launched a new website this week providing more information about the project. After an extensive federal and state approval process, the State of Colorado and the Chatfield water providers are moving toward implementation of the project. The website address is www.chatfieldreallocation.org. The new website includes background on the economic and environmental benefits of storing more South Platte River and Plum Creek water in the reservoir. It includes a history of the thorough review and approvals this project has undergone over the past decade and more. The website also includes information on the studies and plans that are in place for the reallocation project, as well as a map and a list of local, state, federal and environmental entities that support the project. As it becomes available, the website will provide information about the next phases of project planning and design, as well as a construction schedule when it is available. However, we do not expect any major earth-moving or ground disturbing activities will be undertaken this year. Chatfield State Park guests will see no impact to the park and their visits during the summer of 2015. A timeline will be added to the website as soon as start dates are available. The Chatfield dam and reservoir were built in the 1970s for flood control, which remains the primary mission of the facility. The man-made lake was designed to hold more than 350,000 acre feet of water in times of flooding.
