  1. SVRP Bi-STATE STUDY Bob Haynes, IDWR & Keith Stoeffel, WDOE May 9, 2006

  2. HOW WE GOT HERE • Power plant water right filings in Idaho in 2002. • Coalition of Business & Environmental Interests Work for Federal Funding • $500K Startup Funding to USGS in FY2004 • EPA Grants to Washington, Idaho & the Spokane Regional Chamber of Commerce • Funding from Wash. & Idaho Legislatures • MOU signed by USGS, DOE & IDWR

  3. THE BI-STATE STUDY • Governed by a MOU between by the states of Idaho & Washington and the USGS. • Management decisions for the study are made by consensus of states of Idaho, Washington and the USGS. • A Project Technical Leadership Team (PTLT) consisting of a member from each of the states and the USGS manages the study

  4. THE BI-STATE STUDY Cont’d • A Technical Advisory Committee (TAC) consisting of voluntary representatives from the community assists with technical advise. • A Policy Advisory Committee (PAC) consisting of interested stakeholders from the community provides additional public input.

  5. THE BI-STATE STUDY Cont’d • Many meetings to obtain support for the concept of the study • Many meetings to define what was parameters should be studied • Much effort to develop the framework of how the study would be done

  6. THE AQUIFER IN GENERAL • Responds rapidly to precipitation events. • Lowest recorded water occurred in 1932.

  7. THE AQUIFER IN IDAHO • Surface water is tributary to ground water. • Ground water is NOT tributary to surface water so stream flows in the Spokane River are not affected by ground water recharge or ground water pumping.

  8. THE AQUIFER IN WASHINGTON • Surface water is tributary to ground water AND • Ground water is also tributary to surface water.

  9. THE SPOKANE RIVER IN IDAHO • Flows are totally dependant on outflow from Post Falls Dam. • Part of the year the dam controls flows and part of the year the river free flows.

  10. THE SPOKANE RIVER IN WASHINGTON • Flows are dependant on outflow from Post Falls Dam and inflow from the aquifer in a section below Barker Road and in the City of Spokane. • Aquifer discharges are impacted by precipitation and ground water pumping. • The closer the pumping is to the river, the more immediate the impact to the river.
