Book excerpt: Excerpt from Federal-State-Private Cooperative Snow Surveys and Water Supply Forecasts for Montana and Northern Wyoming (Upper Missouri and Upper Columbia River Basins): May 1959 The climate of the cultivated and populated areas of the West is characterized by relatively dry summer months. Such precipitation as occurs falls mostly in the winter and early Spring months when it is of little immediate benefit to growing crops. Fortunately, most of this precipitation falls as mountain snow which stays on the ground for months, melting later to sustain streamflow during the period of greatest demand during late spring and summer. Thus, nature provides in mountain snow an imposing water storage facility. The amount of water stored in mountain snow varies from place to place as well as from year to year and accordingly, so does the runoff of the streams. The best seasonal management of variable western water sup plies results from fore-knowledge of the runoff. A snow survey consists of a series of about ten samples taken with specially designed snow sampling equip ment along a permanently marked line, about 1000 feet in length, called a snow course. The use of snow sam pling equipment provides snow depth and water equivalent values for each sampling point. The average of these values is reported as the snow survey measurement for a snow course. Snow surveys are made monthly or semi-monthly beginning in January or February and continue through the snow season until April, May or June. Currently more than 1300 western snow courses are measured each year. These measurements furnish the key data for water supply forecasts.
