Columbia River Mainstem Water Resources Information System Columbia River Basin 2011 Long Term Water Supply and Demand Forecast The water footprint: water in the supply chain - Arjen Hoekstra February 2013 Federal Support Toolbox for Integrated Water Resources Management - The water challenges facing the nation are compelling and the needs are great. Managing water resources as a collaborative endeavor is crucial to address these challenges and water needs effectively. National Geographic - Water Footprint Calculator (Every Drop Counts) Water Availability in your Watershed (WRIA) To help you understand information about water availability in your Washington state watershed, Ecology created focus sheets with information about each WRIA. The information provided in the focus sheets describe the factors that limit water availability, and other relevant details in that WRIA.

These alerts are official, yet informal notices that describe flood, drought, or water quality conditions across the country, as well as how USGS field crews are responding to the event.
