We protect Spokane’s water - from the mountain to the tap.

Our Aquifer

The Spokane Metro region is fortunate to have the Spokane Valley Rathdrum Prairie aquifer. This aquifer is beneath Spokane County in Washington and Kootenai County in Idaho and it supplies high quality drinking water for over 500,000 people. With a volume of nearly 100 trillion gallons of water, it is one of the most productive aquifers in the country. Above ground, the Spokane region is home to four unique watersheds: the Middle Spokane River, Hangman Creek, Little Spokane River, and Lower Spokane River watersheds – which all converge in Spokane and feed into the Spokane River.

As more people move to the region every year and development expands from urban areas to the far reaches of our urban growth boundaries, it is crucial that we understand how the aquifer and Spokane River interact and recharge.


The Lands Council participates in watershed planning groups in both Washington and Idaho, providing an important conservation perspective during these monthly meetings. This participation allows us to track changes in water quality plans and in-stream flow rules and allows us to give input on proposed water policy, water availability studies, and water quality enhancement projects.

The spokane river clean-up


Each September, The Lands Council leads the largest organized clean-up of the Spokane River. Each year, over 700 volunteers pick up over 4 tons of trash and recyclables. The River Clean-Up goes from Riverside State Park through the downtown Spokane corridor to the Spokane Valley. This amazing, and necessary, event wouldn’t be possible without the collaboration of numerous organizations, volunteers, and businesses.
