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