Snow Water Equivalent Watershed Maps and Reports
Snow water equivalent (SWE) values are derived from measurements taken at snow course and SNOTEL data stations. The amount of water contained in the snow columns are measured and expressed as percent of average and summarized by watershed. Snow water equivalent maps are available for the first of each month from January through June beginning in 2002.
