Nutrient and Suspended-Sediment Transport and Trends in the Columbia River and Puget Sound Basins, 1993-2003

Abstract: The U.S. Geological Survey (USGS) is committed to providing the Nation with credible scientific information that helps to enhance and protect the overall quality of life and that facilitates effective management of water, biological, energy, and mineral resources (http://www.usgs.gov/). Information on the Nation's water resources is critical to ensuring long-term availability of water that is safe for drinking and recreation and is suitable for industry, irrigation, and fish and wildlife. Population growth and… Show more

“…My results also indicate that the lower Columbia River has become increasingly P‐limited since the 1990s—changes likely due to reductions in P in detergents and better wastewater treatment. Seasonal N:P ratio trends were similar downstream at rkm's 85 and 243 indicating broadly similar seasonal nutrient trends in the mainstem Columbia River (Wise et al., ). However, while stoichiometric ratios suggest P limitation in the Columbia River, persistently detectable phosphate could otherwise indicate that phytoplankton may not be nutrient limited (Gilbert, Needoba, Koch, Barnard, & Baptista, ; Sullivan, Prahl, Small, & Covert, ).…”

“…Within the City Limit, nitrogen and phosphorus pollution exports rise by 44% and 157% respectively, and the carbon storage drops by 9%. The high percentage of nitrogen and phosphorus export is consistent with previous research finding that Willamette Basin is facing increasing risk of water contamination due to nitrogen input and phosphorus input [47,48]. All of these three results are less than the general impacts across the entire drainage basin.…”

“…The estimated mean annual flow of the Nooksack River at Ferndale is 109 cumecs for the same period of record. During 1995During -1998 the Nooksack River at Cedarville transported an average of 2.3 million tonnes of suspended sediment load per year (Embrey and Frans, 2003;Wise et al, 2007;Czuba et al, 2011). The Fraser and Nooksack rivers are continuing to build deltas, the form of which is strongly dependent on anthropogenic processes (Fig.…”
