                   Purpose and Goal
• The purpose of this project is to
  provide a scientific foundation for
  management of the SVRP aquifer. The
  study will culminate in the development
  of a numerical ground-water model that
  Washington and Idaho can use to
  cooperatively manage the SVRP aquifer
  and adjacent rivers and lakes
                     Common problems,
                    Uncommon solutions
• Pressures……
  – State Water management agency pressure
     • Cogentrix, etc.
  – Local Government management planning processes
     • WRIA, Kootenai County process
  – Stakeholder/NGO cooperation
     • Policy Advisory Committee
• Product….
  – Three Party Memorandum of Agreement
     • USGS participation, two-state study
• Results….
  – Partnership of state water-management agencies
  – Product-oriented investigation
