Water Conservation

The average person in Spokane County used 217 gallons of water per day in the year 2000.  The Washington State average is 114 gallons per day (USGS, 2004).  According to officials from the Department of Ecology and the Spokane Aquifer Joint Board almost all of the difference is in landscape watering.  Water use during the summer months triples.

The Spokane-Rathdrum Prairie Bi-State Aquifer Study determined that water levels in the aquifer are not declining.  So why the concern over summertime water use?  The study also demonstrated the link between the aquifer and the Spokane River.  Summer withdrawals from the aquifer result in lower flows in the Spokane River.  The Department of Ecology reports that a 10% reduction of summer withdrawals from the aquifer would increase summer flows by 40 cfs, or approximately 5% of August river flow.

Visit the USGS Spokane River Gage at Spokane (just below the Monroe Street Bridge) for real time river flows.
