Publication Summary

Chapter 90.90 RCW directs the Department of Ecology (Ecology) to report data on metered water use. The statute requires major water users in the Columbia River basin to install meters and report their water use to Ecology. By 2009, metering and reporting should be in place for 90% of surface and ground water uses from the Columbia River, and ground water uses within a one-mile corridor on each side of the Columbia River. The data collected will be part of the development of the Columbia River Water information System, a database designed to help the State "better understand current water use and instream flows in the Columbia River mainstem" (RCW 90.90.050). The cost of installing meters will be shared between water right holders and the State ("cost-sharing"). Ecology has allocated $1,000,000 to assist water users with the costs of purchasing and installing meters or metering systems.
