Here is the graphic from Western Water Assessment for streamflow forecast in 2010. This is forecasted as of March 2010 so we will have to wait and see how things really turn out but they have great info at this site. More March info can be found at the Western Water Assessment site. They have excellent reservoir information and temperature and snowpack information as well.
