Chatfield Reservoir Storage Reallocation Reports available for public review


Here’s the release from the US Army Corps of Engineers (Gynn Jarrett):

In accordance with the National Environmental Policy Act of 1969, as amended, the U.S. Army Corps of Engineers has prepared a Final Feasibility Study / Environmental Impact Statement for the Chatfield Reservoir Storage Reallocation, Littleton, Colo.

The final report identifies and compares four main alternatives and outlines in detail the preferred alternative for reallocating storage space in the Chatfield Reservoir for joint flood control- conservation purposes, including storage for municipal and industrial water supply, agriculture, environmental restoration and recreation and fishery habitat protection and enhancement. The National Environmental Policy Act of 1969 requires the Corps to assess and report the socio-economic and environmental effects of reallocating storage for these purposes.

“Extensive coordination with Colorado Department of Natural Resources, the project sponsor, and water providers occurred throughout this project to complete the final report. Representatives from federal, state, local governments and nongovernmental groups such as the Sierra Club and Audubon Society as well as members of the public provided substantial input into the development of this project and provided comments on the draft report. This input was taken into consideration to prepare the final document,” said Gwyn Jarrett, project manager.

The public is encouraged to review the final report and environmental impact statement during the open comment period from Aug. 2, 2013 to Sep. 1, 2013.
BACKGROUND: Population growth within the Denver, Colo., metropolitan area continues to create a demand on water providers. Colorado’s population is projected to be between 8.6 and 10.3 million in 2050. The Statewide Water Supply Initiative, commissioned by the State Legislature, estimates that by 2050, Colorado will need between 600,000 and 1 million acre-feet/year of additional municipal and industrial water. There is also a strong need for additional water supplies for the agricultural community in the South Platte Basin as thousands of acres of previously irrigated land has not been farmed in recent years due to widespread irrigation well curtailments.

The purpose and need of the Chatfield Reservoir Storage Reallocation Study is to increase availability of water, sustainable over the 50-year period of analysis, in the greater Denver area so that a larger proportion of existing and future (increasing) water needs can be met.
