Nonconsumptive Needs Assessment
Committee Work
• Identify and map recreational and environmental
attributes
• Develop recreational and environmental attributes
categories for prioritization
• Map recommended prioritization of recreational and
environmental attributes
• Recommend request for Arkansas Basin participation in
HB1400 funded Watershed Flow Evaluation Tool pilot
project
• Identify available quantification and threats to attributes
• Recommend quantification needs for recreational and
environmental attributes
• Identify high priority recreational and environmental
needs in Arkansas Basin
8
Arkansas Basin Deliverables and
Schedule
• Maps of identified recreational and environmental
attributes – draft complete February 2008
• Maps of recommended prioritization of recreational and
environmental attributes – draft complete February 2008
• Results from pilot project and recommendation about
Tool use in Arkansas Basin – pending approvals
(projected pilots complete by September 2008)
• Recommendations on quantification needs for recreation
and environmental attributes – November 2008
• High priority recreational and environmental needs
identification

Glossary/Terminology
• Attribute – data used to describe a feature. In
this case environmental or recreational features
in a basin.
• Hydrologic Unit – a 4-level heirarchial
classification of hydrological drainage basins in
the U.S.
• Hydrologic Unit Code (HUC) – a unique 2-8 digit
code used to identify each hydrologic unit.
• GIS – a system for capturing, storing, managing,
and analyzing spatial information.

Prioritization Process
• Develop environmental and recreational attribute
maps (9 total for Arkansas Basin)
• Map environmental and recreational attributes
by HUC (9 total for Arkansas Basin)
• Overlay HUCs to show where there is
concentration of recreational and environmental
attributes

Next Steps
• Review mapping which will be available on
www.ibcc.state.co.us
• Provide feedback to the committee
• Roundtable adopt attributes and priorities
