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

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
