The Hood River Watershed Group will host a presentation on a three-year study of the Hood River Basin and how climate change impacts stream flow and the opportunities for a sustainable future. The result of a recently completed County-initiated three-year study, the presentation highlights predicted temperature, precipitation, stream flow, and fish habitat changes from 2030 to 2060. It also describes water conservation strategies for achieving sustainable water supplies and streamflows in the future. The presentation will be Tuesday evening at 7 p.m. in the Hood River County Administration Building.
