Nutrients are a nationally recognized concern for water quality of streams, rivers, groundwater, and water bodies. Nutrient impairment is documented by the U.S. Environmental Protection Agency (USEPA) as a primary cause of degradation in lakes and reservoirs, and nutrients are related to organic enrichment and oxygen depletion, which is an important cause of degradation in streams. Recently (2011), an effort to develop State-based numeric nutrient criteria has resulted in renewed emphasis on nutrients in surface water throughout the Nation. In response to this renewed emphasis and to investigate nutrient water quality for Northern Colorado Plateau Network (NCPN) streams, the U.S. Geological Survey (USGS), in cooperation with the National Park Service (NPS), assessed total nitrogen (TN) and total phosphorus (TP) concentration data for 93 sites in or near 14 National Park units for the time period 1972 through 2007.
