Conservation easements in the Prairie Pothole Region of North Dakota: characteristics of wetland catchments and key factors for determination of drainage setback distances
This data release includes characteristics of wetland catchments associated with U.S. Fish and Wildlife conservation easement lands located in the Prairie Pothole Region of North Dakota. Characteristics include wetland catchment areas, slope length, land use, soil mapping unit, and slope grades of representative soils. County and ecoregion also are included. Summary data pertaining to lateral setback distances, or drainage setbacks, also are presented by county and soil mapping unit for a range of subsurface drainage system characteristics (i.e., drain pipe depth and diameter). Additionally, calculated variables used for data analyses and presentation in the manuscript associated with this data release are included.
Water chemistry of cropped wetlands and associated subsurface drainage system discharge in the Prairie Pothole Region of North Dakota, 2013–2015
A field study was conducted in the Prairie Pothole Region of North Dakota to examine potential effects of localized subsurface drainage systems on wetland hydrology. As part of discrete studies utilizing the study sites (wetland catchments) from this study, samples of wetland surface water and subsurface drainage system effluent were collected from 2013–2016 and analyzed for standard water-quality variables (ions, elements, nutrients), agricultural chemicals (herbicides, pesticides), and metals. This data release presents water-quality data associated with these samples. Surface-water samples were collected from five wetlands and effluent was collected from the two drainage-system outlets from wetland Beck 6 and...
