Water availability
Climate change and water supply
Air & ClimateSurface and groundwater availability varies by watershed and the sub-basins within those watersheds. Water availability also depends on the water rights held by others in each area. If you have questions about water availability for a particular property, identify your watershed, also known as a Water Resource Inventory Area (WRIA).
