Titre de série : U.S. Geological Survey Water Supply, 2240 Titre : Estimation of nonpoint source loadings of phosphorus for lakes in the Puget Sound Region, Washington Type de document : texte imprimé Auteurs : Gilliom, R. J. Mention d'édition : U. S. Geological Survey Editeur : U. S. Geological Survey Année de publication : 1983 ISBN/ISSN/EAN : CI-05097 Note générale : Control eutrophication of lakes in watersheds undergoing development is facilitated by estimates of the amounts of phosphorus (P) that reach the lakes from areas under various types of land use. Using a mass-balance model, the author calculated P loadings from present day P concentrations measured in lake water and from other easily measured physical characteristics in a total of 28 lakes in drainage basins that contain only forest andresidential land. The loadings from background sources to each of the lakes wera estimated by methods developed in a previous study. Differences between estimated present-day P loadings and loadings from background sources were attributed to changes in land use.
