Excerpt from Water Supply Outlook for Washington and Federal-State-Private Cooperative Snow Surveys: As of May 1, 1971A snow cover map is not prepared on the first of May because dur ing normal years many of the snow courses at the lower elevations are reported to have no snow and then on years such as this the snow cover is present at these snow courses which gives a highly biased snowwwater picture. In order to somewhat reduce this con dition any snow course that had a snow cover greater than 2001 was recorded as zooz of normal. 'many of the snow courses measured in the state reached this point as of May 1. Even with this innova tion this month the snow cover improved, percentagewise, over that which was reported last month. Only in isolated watersheds suchas the Kettle, Ahtanum, Green, and Skykomish was there a reduction in the snow cover percentage figures. This, also, was a result of fewer snow courses being measured in these watersheds than are measured on April 1. The snow cover now ranges from a low of 252 above normal for the Kettle River to a high of 832 above for the Snoqualmie River. In areas such as the Lewis River the low=e1eva= tion snow cover is as good or better than that occurring at the upper elevations while over the rest of the state there has been some melting at lower elevations but not to the extent as could normally be expected.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
