17 PMWRC Becomes Inactive (1976) I suggest we better decide soon what the future of our Committee is to be.... assess what our Administrators views are If any agree in principle with the OPAL letter, I m for abandoning further work.

18 IDWR Letter to WDOE This is to advise you of the reason Idaho has protested Application... filed by Washington State University... The model predicts that should withdrawals increase even at a rate as low as one percent per year the aquifer will not reach a recharge/discharge equilibrium and water level declines will continue...

19 IDWR Letter to WDOE I propose... meet. A memorandum of understanding between the two agencies could be developed which would clearly identify the conditions under which additional water use development would be allowed, outline conservation programs which would be enforced, and support the development of a long term management plan for the region

20 WDOE Response to IDWR Letter The Department of Ecology has a great deal of interest. I concur that a meeting between the two agencies should take place to initiate the plan. I would suggest that a representative from each of the two cities and universities... attend the meeting.

21 Resolution of Understanding (PMWRC, IDWR, WDOE) IDWR and WDE further agree to pursue the implementation of a coordinated Washington - Idaho ground water management Plan for the Pullman - Moscow basin in accordance with their respective state law policies. The Pullman - Moscow Water Resources Committee (PMWRC) agrees to work with the state agencies and to serve as the forum for input from local governments, interest groups and private citizens.

22 Ground Water Management Plan

23 Palouse Basin Aquifer Committee "To ensure a long-term, quality water supply for the Palouse Basin region" A Committee (now known as PBAC) was formed in 1967 because of declining groundwater levels in our municipal wells. The Palouse groundwater basin is the sole source of water for over 60,000 residents of Pullman, Washington and Moscow, Idaho and outlying areas in both Whitman County (Washington) and Latah County (Idaho). Also included among our groundwater users are Washington State University and the University of Idaho. We are a multi-jurisdictional, cooperative group with the mission of ensuring a safe and sustainable supply of water for the future.

36 Ground Water Management Plan Chapter Mission and Goals Mission: To ensure a long-term, quality water supply for the Palouse Basin region. Consistent with the Palouse Basin Groundwater Management Plan, develop and Implement a balanced basin wide Water Supply and Use Program by Create and maintain an action plan for aquifer system sustainability, enhancement and/or alternate water supply development. Direct research and implement pilot projects necessary to understand the basin hydrogeology in a manner sufficient to support the Water Supply and Use Program and the affiliated supply projects Encourage and facilitate entities in meeting their specific pumping, WSU Test Well conservation, efficient use, water recycling and other Static Water goals. Level Elevation 2260 Educate entities and the public on the state of the basin water supply and the status of PBAC s mission and goals (ft above MSL) Maintain harmonious and effective working relationships across the 2240 state line to fairly meet the needs of all entities.
