As the state (non‐federal) sponsor of the Chatfield Reservoir Storage Reallocation Study, the CWCB has contracted with the U.S. Army Corps of Engineers (Corps) to complete a Feasibility Report and Environmental Impact Statement (FR/EIS) to investigate the feasibility of “reallocating” some of the storage space in Chatfield Reservoir. The study will examine the potential reallocation of some of the storage space in Chatfield Reservoir from flood control use to multi-purpose use, including up to 20,600 acre feet for municipal & industrial (M&I) and agricultural uses.
The FR/EIS will evaluate the potential impacts and costs of four alternatives: two options for reallocation and two alternatives for water users if no action is taken at Chatfield.
The project enjoys broad support from government agencies, special districts, non-profit interests and elected officials at local, state and federal levels. If approved and implemented, the reallocation of storage space will assist in addressing water supply needs within the South Platte River Basin
The Corps is has released the FR/EIS for public comment on June 8, 2012 and the comment deadline has been revised to September 6, 2012 (see news release from the Corps of Engineers
for more information). After a public comment period, the study will undergo revisions and be released as a Final FR/EIS. Then the Corps will issue a Record of Decision (ROD) on whether a reallocation would be feasible. The Final FR/EIS and ROD are anticipated in 2011.
