Paperback. Zustand: New. Print on Demand. This book presents an analysis of streamflow data collected by the United States Geological Survey in the Yukon - Tanana region of Alaska during 1907 and 1908. The data was collected to support the development of placer mining operations in the recently-established Fairbanks mining district, and to plan water storage and conservation in the region. The book examines the effects of snowmelt and rainfall patterns on streamflow, with a focus on the importance of water storage and conservation in the region. The author's findings provide valuable insights into the development of water storage and conservation plans in the Yukon - Tanana region, especially considering the increased focus on responsible and sustainable resource management within the mining industry.
