“…The application of a specific nutrient export coefficient to an ungaged inflow was based on similarities in hydrology and land use and land cover characteristics. Annual loads of nutrients from atmospheric sources were estimated with data presented by Stanford and others (1983), Hallock andFalter (1987), andNational Atmospheric Deposition Program (1991). The annual areal deposition rates, in kilograms per square kilometer, were multiplied by lake surface area, in square kilometers, to determine the annual load to the lake.…”
