Wastewater Treatment Plant Total Phosphorus Flux Load Estimates Red River of the North Basin The dataset contains estimates for total phosphorus flux from wastewater treatment plants that discharge to surface water within the Red River of the North Basin in the United States and subbasins. Shapefiles defining the subbasins are available as part of the same data release in which these data are published. Estimates of wastewater treatment plant total phosphorus flux (or load) were calculated by Tammy Ivanhnenko for the years 1978, 1980, 1982, 1984, 1986, 1988, 1990, 1992, 1996, 2000, 2004, 2008, and 2012. Flux estimates were based on the average discharge from the wastewater treatment plants and treatment level, both reported as part of the U.S. Environmental Protection Agency's Clean Watershed Needs Survey,...

The shape files that are part of this data release document the basins and the streamgage locations are also provided in an associated shape file.

The Lake Erie survey examined the food web across a nearshore to offshore gradient, matching the sampling design the preceding USGS studies of the other four Great Lakes (2010-2013). We sampled all trophic levels in all three lake basins across multiple seasons in order to determine nutrient availability...

Sampling occurred during 2013 and 2014. In addition, this data set contains evaluations of movement of total phosphorus and water through the reconnecting structure, frequency of changes in flow direction through the reconnecting structure, and dissolved oxygen measurements in the reconnected wetland pool.
