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,...

This child page contains 34 csv files, site_qw_nuts, which contain observations of nitrate plus nitrite as nitrogen (npnN), total nitrogen (TN), total phosphorus (TP) for each site . Each file includes date of observation, measured value of water-quality constituent, remark code for the measured value, and site name. Availability of observations of water-quality constituents depended upon collecting agency and varied by site and constituent. Not all sites had observations for all constituents. The format of the csv file (date format and column headings) is designed to meet the specific requirements of file format for R-QWTREND. If csv files are opened directly in excel, the format of the data can change. To ensure...

This data shows select streamgage locations throughout the Red River of the North Basin upstream of Emerson, Manitoba, and basin outlines for eight subbasins..
The Dakota Water Science Center contributes to regional and national water-resources communities with expertise in water-quality monitoring, streamflow measurement and analysis, water use, and modeling and statistical analysis of hydrologic and other environmental data. We promote collaboration within our scientific community. We help to meet the mission of the U.S. Geological Survey by collecting and disseminating reliable, impartial, and timely information that is needed to understand the Nation's water resources.

This child page contains a zipped folder which contains all files necessary to run trend models and produce results published in U.S. Geological Scientific Investigations Report 2020–5079 [Nustad, R.A., and Vecchia, A.V., 2020, Water-quality trends for selected sites and constituents in the international Red River of the North Basin, Minnesota and North Dakota, United States, and Manitoba, Canada, 1970–2017: U.S. Geological Survey Scientific Investigations Report 2020–5079, 75 p., https://doi.org/10.3133/sir20205079]. The folder contains: six files required to run the R–QWTREND trend analysis tool; a readme.txt file; an alldata.RData file; a siteinfo_appendix.txt: and a folder called "scripts". R–QWTREND is a software...

A comprehensive study to evaluate water-quality trends in the international Red River of the North basin and to assess water-quality conditions for Red River of the North crossing the international boundary near Emerson, Manitoba was completed by the U.S. Geological Survey (USGS) in cooperation with the International Joint Commission, North Dakota Department of Environmental Quality (NDDEQ) and Minnesota Pollution Control Agency (MPCA), and in collaboration with Manitoba Sustainable Development (MSD) and Environment and Climate Change Canada (ECCC). In this dataset a zipped folder is provided which contains all files necessary to run models and produce results published in U.S. Geological Scientific Investigations...

The dataset contains estimates of annual flow and annual flux in kilograms for six sites in the Red River of the North Basin (identified as basin 1, 2, 3, 4, 5, and 8). 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.

These data describe the percent of cropland harvested as wheat, corn, and soybean within each basin (basins 1-8, see accompanying shapefiles). Data are available for other crops; however, these three were chosen because wheat is a traditional crop that has been grown for a long time in the Basin and corn and soybeans have increased in recent times because of wetter conditions, the demand for biofuels, and advances in breeding short-season, drought-tolerant crops. The data come from the National Agricultural Statistics Service (NASS) Census of Agriculture (COA) and have estimates for 1974, 1978, 1982, 1986, 1992, 1997, 2002, 2007, and 2012. Years with missing data were estimated estimated using multivariate imputation...

These data report the percent of crop acreage, within each basin (basins 1-8, see accompanying shapefiles), enrolled in the Conservation Reserve Program (CRP).

This child page contains 34 csv files, site_qw_ions, which contain observations of chloride (cl), sulfate (sul), total dissolved solids (tds), or total suspended solids (tss) for each site. Each file includes date of observation, measured value of water-quality constituent, remark code for the measured value, and site name. Availability of observations of water-quality constituents depended upon collecting agency and varied by site and constituent. Not all sites had observations for all constituents. The format of the csv file (date format and column headings) is designed to meet the specific requirements of file format for R–QWTREND. If csv files are opened directly in excel, the format of the data can change....

This child page contains 34 csv files, site_flow, which contain daily streamflow values for each site. Each file includes a station identifier, date of observation, measured value of streamflow and qualifier code for the measured value. The format of the csv file (date format and column headings) is designed to meet the specific requirements of file format for R-QWTREND. If csv files are opened directly in excel, the format of the data can change. To ensure the data are in the proper format for R-QWTREND, files should be opened in a text editor. The "site" in site_flow can be cross-referenced to the main report by downloading the zipped folder RRTrend from child page, "Scripts to run R-QWTREND models and produce...

The Red River of the North (Red River) transports phosphorus from North Dakota, Minnesota, and South Dakota, to Manitoba, Canada, and eventually into Lake Winnipeg. Phosphorus load (or flux) is the amount of total phosphorus (TP) transported by the Red River. The effect of TP load on water quality is a concern, especially with respect to downstream eutrophication issues in Lake Winnipeg, Manitoba, Canada. There is interest at the State and International level to reduce TP flux – an expensive proposition, depending on the method (controlling sources, settling ponds, buffer strips, changes in land use) that is not always effective during spring runoff. The purpose of the study for which these data were developed...
