Excerpt from Water Supply Outlook for Washington and Federal-State-Private Cooperative Snow Surveys: March 1, 1971The water supply outlook for irrigation and_power in the Columbia Basin in Washington and its tributary areas can still be unsiderm ed very good for this thme 'of yearo Snow surveys made on the first of March indicate a snowpack that ranges from.a low of 9% below normal to a high of 922 above° Incomplete results were the story over most of the western Washington area due to storm.per= iods during the measurement timeso Helicopter flights were grounded and 'many of the snow courses were not measured in time to be included in this report. This information will be publishe ed with the April 1 snow results next month° While 'most of the snow measurements were obtained prior to the storm.period compare isons of the snowpacks with those measurements made after the storm period are not truly comparableo A truer picture will be obtained on April 1, hopefully, when all snow courses can be -measured without additional input of snow from one snow course to the other during the measurement schedule° The snow courses all have less water equivalent, percentagewise, than was reported last month at this timeo This is a result of the lack of precipw itation input during the month of Februaryo Valley precipitation stations indicate that only the Columbia Basin in Canada and the northwestern lpes of the Cascades had above=normal precipitae tion input. With the exception of the Conconully reservoir and Salmon Lake, all irrigation reservoirs have abovewnormal amounts of water in storage as of March_1, Power reservoirs are all in good shape having well abovemaverage amounts of stored waters° This increase in reservoir storage is a result of the aboveenor= 8 'mal flows during the month of Februaryo Only the Okanogan River, the Palouse River, the Walla Walla River and the Chehalis River had below°normal runoff during the month of Februaryo Of the rec ported streams the Chelan River had the highest percentage rumfif.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
