1. Prepared for TACIR by Mary R. English, Ph.D., and Roy Arthur Institute for a Secure and Sustainable Environment University of Tennessee, Knoxville

2. Why Statewide Water Supply Planning is Needed Serving the unserved Preparing for growth Balancing uses and needs All but one contiguous state engages in planning. TACIR 2

3. 3 Texas Tennessee Pennsylvania West Virginia Virginia North Carolina Georgia South Carolina Florida

4. Planning in Other States Widely Shared Features: Short-term and long-term planning Watershed-based planning Planning for both groundwater and surface water Water allocation strategies only after extensive planning TACIR 4

5. Planning in Other States Other Basic Features: Legislatively mandated planning? Locus of planningcentral, regional, local? Broad participation? Gathering databefore or during? TACIR 5

6. Planning in Other States Forward-thinking Features: Critical areas planning Conjunctive management Linking quantity and quality Conservation and efficiency TACIR 6

7. Planning Cousins Registering/permitting large water withdrawals Regulating inter-basin transfers TACIR 7

8. Complicating Factors The federal role in managing some state waters Other states claims on interstate water resources TACIR 8

9. Water Rights Law Surface water Riparian rightsright to natural flow Appropriative rightsfirst in time, first in right Regulated riparianism reasonable/beneficial use doctrine Groundwater Absolute dominionunlimited withdrawal Reasonable useon overlying land and non-injurious to other landowners TACIR 9

10. Implications for Tennessee Strengths to build on The basicsregistering withdrawals, regulating transfers, water resources advisory committeeare in place. The pilots were selected based on vulnerability. Room for improvement Integrating quality and quantity Watershed-based approach TACIR 10

11. At this juncture in Tennessee, the future direction of statewide water resource planning is not fully set. Tennessee needs to tailor its own approach, mindful of its own laws, water resources, and water needs. Much can be learned, however, from other states that are further underway with integrated water resources planning. Mary R. English & Roy Arthur TACIR 11
