Excerpt from Changes in Water Quality and Climate After Forest Harvest in Central Washington StateWatershed studies within this forest zone are limited. Watersheds in the Entiat Experimental Forest in central Washington State were to have addressed the question of how logging systems could be designed to minimize hydrologic impacts (helvey and others 1976a). Wildfire in the early ig7o's, however, changed the mission of the Entiat Experimental Forest to documenting wildfire effects and monitoring rehabilitation efforts (helvey and others 197gb). Tiedemann and others (1978) described the nutrient economy of the Entiat streams for the postfire years of 1971 to 1975 and provided some benchmark nutrient output levels. Unfortunately, only a limited record existed for the prefire period.The continued need for information on watershed processes under management led to selection of the Hansel Creek and Allen Creek watersheds, the first of a series of new watersheds to be studied. Although 20 watershed complexes were identified for an extensive study of the effects of forest harvest on water quality and yield, only the Hansel and Allen watersheds were developed. This report presents a case history of the changes in streamflow quality and climate of these watersheds as affected by forest harvest.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
