Our Water. Our Future. IWAC Aquifer Video
The Idaho Washington Aquifer Collaborative (IWAC) in partnership with KSPS Public Television produced this awesome video about the Spokane Valley Rathdrum Prairie Aquifer, our sole source of drinking water.
The Adventures of Drippy the Water Drop – A Water Cycle Lesson
Let Drippy the Water Drop help your students understand the water cycle and how precipitation feeds the Spokane River and the SVRP aquifer. Students will also see how water from the aquifer gets to our homes. Have fun with Drippy.

Ty Wick – Lifetime of Water Stewardship Recognition
SAJB President Ty Wick, was honored on March 17, 2017 at the Spokane River Forum H2O Breakfast for 40 plus years of dedication to safe drinking water.
H2O Breakfast Acknowledges IWAC
Let’s be honest, there’s a lot of anxiety going on, and it’s not just emanating from the halls of Washington D.C. In the Evergreen state, 2016 saw a “process” to develop a “process” to develop clean water guidance. That’s the equivalent of being told to shelter in place.

The Spokane River: Modeling in a Changing Environment
WSU, CWU, Uof I and the University of Utah are collaborating on a NSF and USDA funded research grant named WISDM. Tung Nguyen and Heather Baxter explain the technical aspects to modeling the Spokane River ‘s low flow trends in a changing environment.
WISDM Presentation 4/8/14 – Melanie Thornton
The Watershed Integrated System Dynamics Modeling (WISDM) mission is to understand how climate and land use changes have affected water quantity and quality in recent decades, and how will climate variability and change impact water quantity and quality in the next few decades.
Spokane County Water Demand Forecast 3/11/14
Mike Hermanson, Spokane County Water Resource Specialist, presented a summary of the development process and data collected to create, modify and update the Spokane County Water Demand Forecast model.

Spokane Valley Land & Water Company Canal 1907
A 1907 irrigation canal system from Post Falls Idaho to the Spokane Valley is recorded in the National Register of Historic Places and provides an example of bi-state collaboration.
Watershed Integrated System Dynamics Modeling
The WSU WISDM System Dynamics is an approach to studying and managing complex change over time for the SVRP Aquifer and Watersheds. It addresses internal feedback loops and time delays that affect the behavior of the entire system.
2012 SVRP Aquifer GSI Groundwater Flow Model
The 2012 SVRP Aquifer ground-water update and expanded model was commissioned by the City of Spokane, SAJB and the WA Department of Health Drinking Water. Based on the 2007 USGS modelling, it uses Microfem technology and a resolution that supports wellhead protection planning. John Porcello, Senior Groundwater Hydrologist at GSI Water Solutions, presented the model as a tool for wellfield-scale analysis as well as groundwater source management.
