<br />19 <br /> <br />C. Interrelationships of other Land Uses to Water <br /> <br />Yields and Quality <br /> <br />Review the literature and describe in summary fashion <br /> <br />the impacts of other land use activities on water yields and <br /> <br />the flow of streams. Extract data from the literature which <br /> <br />document or,illustrate these impacts. Particular attention <br /> <br />should be accorded grazing, timber harvest, highway and road <br /> <br />construction, wildlife and mineral exploration and exploitation <br /> <br />in respect to their effects on the water resource~ Present <br /> <br />available data which throw light on the adequacy of protection <br /> <br />to watersheds under private owner8hip. Analyze and summarize <br /> <br />~ll available information which indicates the results of <br /> <br />federal watershed rehabilitation and manageme~t programs on <br /> <br />water yields and quality. <br /> <br />IV. ANALYSES OF DATA <br /> <br />A. Present Conditions <br /> <br />1. Tabulate data on stream flow and water yields <br /> <br />in the public land s~ates by drainage area. <br /> <br />Compute the proportion originating on public <br /> <br />lands and identify the principal water-source <br /> <br />areas on maps which show public land ownership. <br /> <br />Estimate the proportion of high water~producing <br /> <br />. . <br /> <br />'lands in public ownership by agency by state. <br /> <br />3260 <br /> <br />.~ <br />
