4.6 River Rehabilitation Floodplain Management Needs Inventory

The Board recommends it be authorized to expend up to$lOO,OOO from the Construction Fund
to develop a scope of work and contract for services to conduct a statewide inventory of river
. channel rehabilitation and floodplain management needs. The findings of the needs assessment will
be the basis for a proposal to determine the economic feasibility of establishing a statewide
floodplain management and river channel rehabilitation program funded separately from the
Colorado Water Conservation Board Construction Fund. The proposed program would represent
a comprehensive approach and source offunds for local governments to better manage and address'
multi-objective river issues including floodplain management, flood hazard mitigation measures,
streambank and channel erosion, maintenance of channel conveyance, and wildlife habitat areas.

4.7 Chatfield Reservoir Reallocation Study

The Board recommends it be authorized to expend up to $300,000 from the Construction Fund
to cooperate with the Army Corps of Engineers, the Urban Drainage and Flood Control District,
interested local governments, and other water users, in a reconnaissance study to be conducted in
1997 for the potential reallocation of flood control storage space to municipal water supply storage
in Chatfield Reservoir.

The purpose of this reconnaissance study would be to analyze existing and alternative operations
of the Chatfield Reservoir individually and, to the extent necessary, systematically with the Cherry
Creek and Bear Creek reservoirs, in order to determine the advisability of undertaking a more
detailed and more expensive investigation concerning the feasibility of reallocating storage in the
flood control pool of Chatfield reservoir, either permanently or on a seasonal basis, to the
conservation pool for water supply purposes. The reconnaissance study will estimate potential
changes to downstream flows and to reservoir pool elevations as well as the potential consequences
to water supplies, flood damages, recreation opportunities, water quality, fish and wildlife habitat,
and other resources.

Expenditure of the funds shall be contingent upon the Board receiving a commitment from the
corps of engineers that these expenditures, and significant in-kind services provided through the
board staff, along with any similar contributions by other non-federal participants, will be recognized
and credited appropriately in the negotiated cost share agreement for funding and implementation
of a formal feasibility study, should the Board and the Colorado Department of Natural Resources
decide to proceed with that level of analysis.
