This file contains the polygon SDE Feature Class for Federal Fluid Minerals(Oil and Gas) for the Bureau of Land Management(BLM) Montana/Dakotas. Federal Fluid Minerals as well as Federal Lease status and Indian Minerals/Leases are included. Plat maps are used to find federal mineral ownership and the Bureau of Land Management's LR2000 database is used to find current leasing status. Assistance from the Bureau of Indian Affairs is used to find Indian Mineral/Lease status. BLM Field Office with Oil and Gas responsibilities (Great Falls, Miles City, or North Dakota) provide final review of data.

DescriptionThe map shows the location where oil spills and brine spills have been documented by the US Department of Transportation Pipeline and Hazardous Materials Safety Administration (PHMSA) and the State of North Dakota's Department of Health. LayersOil Spills- Pipeline SpillsThe types and relative volumes of oil spills are shown on the map using different colors of markers and sizes of the markers.Types include: Equipment Failures, Storage Failures, Vehicle Accidents, Wellhead SpillsSource: PHMSA.dot.govUpdated July 2019Uncontained Oil Spills by VolumeSpills that were not contained by the boundaries of oilwell pads were mapped, and the volumes of the spills are shown by the size of the marker.Source: https://deq.nd.gov/Spills/Data from Jan. 1, 2014-July 19, 2019North Dakota Brine Spills by VolumeBrine is the saline wastewater resulting from oil and gas exploration and production. It is enriched with a variety of toxic elements and compounds.Source: https://deq.nd.gov/Spills/Data from Jan. 1, 2014-July 19, 2019ND PipelinesThe layer shows the locations of major pipelines.Source: PHMSA.dot.govUpdated July 2019ND Oil FieldsThe layer shows the areal coverage of oil fields in North DakotaSource: https://www.dmr.nd.gov/OaGIMS/viewer.htmUpdated July 2019North Dakota Flood Plains - Mandatory InsuranceTo proactively assess and address flooding risks to the public, the U.S. Federal Emergency Management Agency (FEMA) has developed the National Flood Insurance Program (NFIP). This program was created by Congress in 1968 to help provide a means for property owners holding federally backed mortgages to financially protect themselves in the event of a flood. Flood insurance is mandatory if you live in a high-risk area and have a mortgage from a federally regulated or insured lender.Source: https://www.fema.gov/media-library/assets/documents/12886Updated July 2019North Dakota Flood Plains - 500 YearThe "500-year flood" corresponds to an AEP of 0.2-percent, which means a flood of that size or greater has a 0.2-percent chance (or 1 in 500 chance) of occurring in a given year.Source: https://www.fema.gov/media-library/assets/documents/12886Updated July 2019North Dakota Flood Plain - FloodwayA "Regulatory Floodway" means the channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than a designated height. Communities must regulate development in these floodways to ensure that there are no increases in upstream flood elevations. For streams and other watercourses where FEMA has provided Base Flood Elevations (BFEs), but no floodway has been designated, the community must review floodplain development on a case-by-case basis to ensure that increases in water surface elevations do not occur, or identify the need to adopt a floodway if adequate information is available.Source: https://www.fema.gov/media-library/assets/documents/12886Updated July 2019

The selection of geological basins from the 1995 National Oil and Gas Assessment Province Boundaries that (1) intersected with the historical Sage-grouse geographic range, and (2) contained significant oil and/or natural gas reserves according to the U.S. Geological Central Energy Team. Data defining (1) can be found at: http://sagemap.wr.usgs.gov/ftp/regional/wdfw/sagerange.zip and (2) can be found at: http://certmapper.cr.usgs.gov/data/noga95/natl/spatial/shape/pr_natlg.zip. The present data layer was selected from (2) and reprojected to match the Albers projection used in the Rangewide Conservation Assessment.

This dataset represents lineaments in the Powder River Basin as identified in the following U.S. Geological Survey Professional Paper: Anna, L.O., 1986, Geologic framework of the ground water system in Jurassic and Cretaceous rocks on the Northern Great Plains, in parts of Montana, North Dakota, South Dakota, and Wyoming: U.S. Geological Survey Professional Paper 1402-B, 36 p. A lineament is defined as a linear topographic feature of regional extent that is believed to reflect crustal structure (Hobbs et al., 1976, p. 267). Lineament features were transferred from the publication to a hard-copy base map by province geologist, then digitized and referenced for use in a Geographic Information System (GIS). Lineaments may: 1) enhance secondary reservoir permeability and 2) provide migration pathways in unconventional rocks.

These data show the elevation in feet above mean sea level of the base and top, the extent, the elevation in feet above mean sea level for the potentiometric surface, and the concentration in milligrams per liter (mg/L) of total dissolved solids in ground water of the Dakota aquifer in Kansas. The data presented can be used to delineate the dominant features of the regional flow system within the Dakota aquifers. Such information is valuable in studies focusing on the management of water resources in the Dakota aquifers and other hydraulically connected sources of water. This data is from the Kansas Geological Survey - Geohydrology. The Dakota aquifer consists of sandstone bodies in the Cretaceous Dakota Formation and Cheyenne Sandstone. The coverages were developed from 1:100,000-, 1:175,000-, 1:500,000-, and 1:1,000,000-scale information. The data used to construct the top and base altitude coverages are from oil and gas exploration and production wells penetrating the Dakota aquifer. The data used to map the altitudes consist primarily of gamma ray logs and supplemented by drillers' logs in the Salina basin of north-central Kansas.
