1. Local Water Supply Plan Summary
Overall Goal: to enhance the welfare of Yadkin-Pee Dee residents by jointly planning for the sustainable use of water from the Yadkin-Pee Dee River Basin
Project Purpose: first step in joint planning
pull together and put into larger context individual members’ Local Water Supply Plans
maps and summary document will provide “big picture” perspective on the region’s water supply issues
identify key issues the group may want to investigate further for regional water supply planning and coordination of drought response
prepare for the State’s upcoming Yadkin River Basin planning process.

6. Water Supply Summary Based on regular purchases:
13 independent systems (blue)
9 groups of systems (orange)

7. Duke Energy Net Withdrawals
Data are from Union County IBT water supply analysis documents, generated in 2013 based on 2010 Duke Energy planning documents.
Updates may result in changes, especially for the Blewitt Falls and Lake Tillery projected power plant projections (likely lower).
Planning updates are a major undertaking and can take 1-2 years.
