The 17 October 2016 issue of The Christian Science Monitor could not resist using it in its cover story of the Yakima Basin in Washington, A Way Past Water Wars. Zack Colman's article is pretty good but it doesn't put much emphasis on the need for Federal $$$ to make harmony last.
Here in Oregon and California, the Klamath Basin 'peace plan' fell apart because Congressional support to the tune of several hundred million dollars did not materialize. It looks like it might be resurrected.
Here is a link to Colman's article on the CSM site.
The Yakima Basin Integrated Water Resource Management Plan (YBIP) is a key element of the 'harmony'. The YBIP was awarded the AWRA's inaugural IWRM project award in 2012. The Plan's development was led by Washington State's Office of
Columbia River (OCR), the U.S. Bureau of Reclamation, and HDR.
I do have a connection to the Yakima Basin. I took my 2016 summer graduate class to the Yakima Basin as part of their class project and I may be involved in a managed aquifer recharge project in the basin. I was a member of the AWRA committee that selected the YBIP for the IWRM award.
As for 'peace in the valley' (PITV), read my 18 November 2015 blog post. I must thank Tony Willardson, ED of the Western States Water Council, for that term as applied to the Yakima Basin. I am optimistic about PITV for the Yakima Basin - more so than for the Colorado Basin. For one thing, it's much smaller (6,150 versus 250,000 square miles) and more homogeneous. There is more opportunity for residents to interact and meet each other - more sense of 'You're my neighbor, we're in this together.' I suspect it is hard for a Utahan or New Mexican to feel such a kinship with a Los Angeleno or San Diegan, and vice versa.
I met some remarkable people in the Yakima Basin - government workers, irrigators, tribal members, environmentalists, and others. The ones I met - admittedly a very small sample - were enthusiastic about the prospects for PITV.
