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.

In the Prairie Pothole Region (PPR) wetland plant, invertebrate, and waterbird productivity are primarily driven by water-level dynamics in response to climate cycles. Large proportions of wetlands in the PPR have been drained, often consolidating water from smaller to larger-interconnected wetlands. This project will examine whether large basins that receive inflow from consolidation drainage have reduced water-level dynamics in response to climate cycles than those in undrained landscapes, resulting in relatively stable wetlands that have lower densities of invertebrate forage for ducks and shorebirds. We will also include a sample of wetland historically used by piping plovers to assess the threat of consolidation...

Dataset contains locations of subsurface drainage tile permits in North Dakota obtained from the North Dakota State Water Commission as of February 2016. This dataset was updated on 4 August 2016 with additional subsurface drainage permits and supersedes the previous version. Date range of permits (Start & End Dates) in this version has changed from previous version because of the following criteria. Permit applications that were marked as "approved" by the State Water Commission were retained in this dataset, all other status types (e.g., pending, denied) were removed. This dataset provides the latitude, longitude, and polygon outline of the location given on the permit, which is not provided by the State Water...
The enhancement of agricultural lands through the use of artificial drainage systems is a common practice throughout the United States, and recently the use of this practice has expanded in the Prairie Pothole Region. Many wetlands are afforded protection from the direct effects of drainage through regulation or legal agreements, and drainage setback distances typically are used to provide a buffer between wetlands and drainage systems. A field study was initiated to assess the potential for subsurface drainage to affect wetland surface-water characteristics through a reduction in precipitation runoff, and to examine the efficacy of current U.S. Department of Agriculture drainage setback distances for limiting these...

This project contains related research product materials for the assessment of agricultural subsurface drainage tile systems on wetland hydrology in the Prairie Pothle Region. Materials included: downloadable files of drainage tile locations based on tile drainage permits collected from state, county, and local agencies in North and South Dakota. These files can be used to develop a spatial depliction of tile systems at the quarter-quarter level of a section of the TRS system. See associated metadata for information about the data included in the files.

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...
Use of agricultural subsurface drainage systems in the Prairie Pothole Region of North America continues to increase, prompting concerns over potential negative effects to the Region’s vital wetlands. The U.S. Fish and Wildlife Service protects a large number of wetlands through conservation easements that often utilize standard lateral setback distances to provide buffers between wetlands and drainage systems. Because of a lack of information pertaining to the efficacy of these setback distances for protecting wetlands, information is required to support the decision making for placement of subsurface drainage systems adjacent to wetlands. We used qualitative graphical analyses and data comparisons to identify...

Dataset contains locations of subsurface drainage (tile) permits in South Dakota obtained from County and Local Water Board records in South Dakota. The counties included in this dataset are: Brown, Deuel, Grant, Hamlin, Hanson, Kingsbury, Lake, McCook, Minnehaha, Moody, Roberts, Spink, and Turner. The date permits records were collected by this survey vary by county. Other counties in the eastern portion of the state not included in the preceeding list of counties either did not require a drainage permit or permit data was not available at the time of this survey. A majority of permits were collected as of January 2012. Two counties (Hanson and Minnehaha) were updated in December,2013. The permit location (in...

A study was conducted to assess the efficacy of drainage setbacks for limiting effects to wetlands in the Prairie Pothole Region, USA. Surface-water levels, along with primary components of the wetland water balance, were monitored at four wetland catchments over 3 years. During the second year of the study, subsurface drainage systems were installed in two of the wetland catchments using drainage setbacks, and the drainage discharge volumes were monitored. A catchment water-balance model also was used to assess the potential effect of subsurface drainage (i.e., reduced precipitation runoff) on wetland hydrology, and to assess the efficacy of drainage setbacks for mitigating these effects. These data directly support...
