Feasibility Report and Environmental Impact Statement
Reservoir Use Under Reallocation
The concept of reallocation is to convert pool space from one type of storage use to another.
In this case, a reallocation would re-designate water storage space in Chatfield Reservoir that is currently exclusively reserved for flood control purposes to storage space for joint flood control and conservation purposes.
This is achieved by raising the top elevation of the existing multipurpose-conservation pool, effectively increasing capacity for multipurpose water.The expanded multipurpose pool would be re-designated as the “joint flood control-conservation” pool.
A reallocation would have no negative impacts on the originally-authorized flood control purpose of the dam and reservoir. Through modification of the water control plan, a reallocation could also be accomplished without the need to raise the existing maximum flood control pool elevation. This study will analyze necessary mitigation options and modification strategies needed to offset impacts to the environment, recreation and infrastructure in and around Chatfield State Park.
