|The U.S. Geological Survey (USGS) provides the Nation with reliable, impartial earth science information to describe and understand the Earth. In North Dakota, the USGS collects data and conducts interpretive investigations in cooperation with more than 30 local, State, and Federal agencies and Indian Tribes. These basic data and issue-relevant investigations provide the types of information on water, biological, energy, and mineral resources that are needed on a continuing basis by those who are responsible for managing the State's natural resources.|
Devils Lake Basin is a 3,810-square-mile closed drainage basin. (A closed
drainage basin has no outlet to the ocean.) About 3,320 square miles of
the drainage area is tributary to Devils Lake. Lake levels were recorded
sporadically from 1867 to 1901, when the USGS established a gaging station.
For the period of record, the maximum lake level was 1,438 feet above sea
level in 1867, and the minimum lake level was 1,400.9 feet above sea level
in 1940. On June 30, 1996, the lake level was at 1,437.7 feet above sea
level. In response to the rising water levels, the Devils Lake Basin
Interagency Task Force, which comprises many State and Federal agencies,
was formed in May 1995 to find and propose intermediate (5 years or less)
solutions to reduce the impacts of high lake levels (fig. 1). Analyses of future lake-level
probabilities and associated economic damage estimates are required to
evaluate the benefits and costs of proposed flood-control or
The USGS, in cooperation with the North Dakota State Water Commission
(NDSWC), conducted a study to estimate future lake-level probabilities.
Probability data were used by the U.S. Army Corps of Engineers (USACE) to
develop damage-frequency relations for Devils Lake. Periodically updating
the model to reflect the most recent hydrologic conditions for Devils Lake
allows the Task Force to base decisions on the most up-to-date hydrologic
information. The USGS is helping the USACE and the NDSWC in their Devils
Lake Stabilization Feasibility study to understand how various outlet
options affect future lake levels and water quality of Devils Lake. The
study also will help determine how the various outlet options could affect
the hydrology and water quality of receiving streams.|
For the flood-control and lake-stabilization studies, many map products recently have been produced for the Devils Lake Basin. In addition, 19 1:24,000-scale topographic maps were revised. High-resolution digital elevation models are being developed to assist State and Federal agencies in making critical management decisions.
Among the most popular and versatile products of the USGS are its
1:24,000-scale topographic maps (1 inch on the map represents 2,000 feet on
the ground). These maps depict basic natural and cultural features of the
landscape, such as lakes and streams, highways and railroads, boundaries,
and geographic names. Contour lines are used to depict the elevation and
shape of terrain. North Dakota is covered by 1,464 maps at this scale,
which are useful for civil engineering, land-use planning, natural-resource
monitoring, and other technical applications. These maps have long been
favorites with the general public for outdoor uses, including hiking,
camping, exploring, and back-country fishing expeditions.
The USGS has been working with State and Federal representatives to coordinate and produce standard products and digital cartographic data in North Dakota to meet a variety of user needs. Its geographic location in the Northern Great Plains, mixture of mineral resources and agriculture, and segmented population distribution are important factors that affect natural-resource and habitat-management issues. The availability of basic categories of digital cartographic data, such as elevation, hydrologic, and transportation data sets, will allow for improved natural-resource management, hydrographic investigations, and modeling of various physical processes by using geographic information system (GIS) technology. These activities in North Dakota exemplify how government agencies can work together to reduce duplication of effort and resources used, while increasing efficiency in managing their respective responsibilities.
|The State of North Dakota established a Geographic Information System Technical Committee (GISTC) and the State Mapping Advisory Committee (SMAC) by Executive Order in May 1995. These committees will work with the USGS and other Federal agencies to coordinate state GIS and mapping activities, which include digital spatial data holding and clearinghouse activities. The GISTC will keep governmental agencies and the public informed with respect to GIS technologies and GIS projects, standards, and digital spatial data availability, and the SMAC will coordinate and prioritize mapping requirements in the State.|
Nationally consistent and comparable information is needed to make valid
regional and national statements about water-quality conditions now and in
the future. The USGS's National Water-Quality Assessment (NAWQA) Program
was established to address these needs. The goals of the NAWQA Program are
to describe the status and trends in the quality of a representative part
of the Nation's surface- and ground-water resources and to provide
scientific understanding of the natural and human factors that affect water
The Red River of the North (Red River) study unit was started in 1991 (fig. 2) to assess the water-quality issues of nutrients and pesticides from nonpoint sources. Local and regional issues also were identified through a study-unit liaison committee and considered in the Red River study unit assessment. These included soil erosion, sedimentation, natural salinity from ground water, and contamination from point sources, particularly to the Red River. Intensive data collection included water chemistry in streams and shallow aquifers; suspended sediment and bottom sediment in streams; the variety and number of fish, aquatic insects, and algae in streams; and contaminants in fish tissues was completed in 1995.
The Red River study is producing water-quality information that is useful to policymakers and water managers at all government levels. For example, the amount and types of pesticides and nutrients measured in streams and surficial aquifers are compared with estimates of land applications of these compounds for various landscapes, seasons, and weather conditions within the study area. The NAWQA study has fostered cooperation among State agencies in North Dakota and Minnesota and various Provincial and Federal Canadian agencies.
North Dakota faces long-term challenges related to land-use and
land-management practices and engineering construction. Use of the land
contributes to environmental changes (erosion, reservoir siltation) and
natural hazards (floods, landslides, swelling and collapsing soils). The
USGS, in cooperation with the NDGS, is involved in studies to provide
information about the distribution of geologic resources and to identify
potential consequences of land-use and land-management practices. The
distribution, thickness, and chemical, physical, and engineering
characteristics of surficial geologic deposits are being mapped as part of
the compilation of the Quaternary Atlas of the United States. Bedrock
geology, areas of active surface processes (erosion, deposition), areas of
geologic hazards, and other aspects of geology and hydrology that affect or
are affected by continued development of the land surface in parts of North
Dakota are being mapped in detail as part of a regional study of
environmental change in the Missouri River drainage basin.
|statemap is one of the external funding opportunities offered by USGS National Cooperative Geologic Mapping Program. Agreements are open to the State Geologic Surveys. Proposals focus on such issues as ground-water quality, geologic hazards, landfill siting and management, oil and gas assessments, coal quantity, sand and gravel resources, and economic mineral development. For example, statemap funds detailed geologic and paleontologic mapping that is needed to make land-use decisions in Theodore Roosevelt National Park, and that is being used to develop visitor programs and interpretive materials on the geology of the area.|
The USGS, in cooperation with about 30 local, State, and Federal agencies,
operates an extensive hydrologic data-collection program. During 1996, the
program provided for the collection of data at 173 streamflow and
lake-level stations, 141 ground-water observation wells, 185 water-quality
and sediment stations, and 2 atmospheric-deposition stations. Current-year
data, which are published annually, are critical for daily administrating
and managing of water resources, determining the extent and severity of
droughts, characterizing and predicting conditions during floods, and
monitoring the effects of human activities on streamflow, ground water, and
water quality. The data also are essential to interpretive studies that
provide information for making decisions about water issues that
potentially affect all North Dakotans. Locations where surface-water data
have been collected over the years by the USGS are shown in figure 3.
Data at 38 streamflow stations and 3 reservoir sites are being relayed on a
real-time basis to the USGS computer in Bismarck. These data can be
accessed immediately on the North Dakota District Home Page on the World
Wide Web at:|
Streamflow and stage information for the last 7 days is provided in graphic form along with such information as station location and length of record. The importance of the streamflow network was demonstrated during the floods of July and August 1993 and April 1996, when streamflow data transmitted by satellite telemetry were used by several agencies to manage storage and releases from reservoirs and to forecast floods.
The USGS, in cooperation with the NDSWC and the NDGS, has completed
reconnaissances appraisals of ground-water availability and quality in each
county in North Dakota. The county ground-water studies determined the
availability, movement, recharge, discharge, and quality of water in
glacial and bedrock aquifers. Information from the county studies has
provided a scientific basis for addressing many ground-water issues, such
as water availability and water allocation.
|In 1993, the USGS, in cooperation with the NDSWC, began a series of studies to describe the water resources of the State by river basin. The first study, which is being done in the James River Basin, describes the hydrologic system of the Basin and includes analysis of the major rivers and related reservoirs, wetlands, major types of aquifers, soil system, and climate. Study results are useful to water-management officials and the public for making informed decisions about water projects or other issues related to North Dakota's water resources.|
|The USGS Biological Resources Division (formerly the National Biological Service) conducts research and provides the scientific data needed for sustained economic benefits from and conservation of the grassland ecosystems of the northern Great Plains. Ongoing research at the Northern Prairie Science Center (NPSC) in James-town, includes studies to document the wildlife values of the Conservation Reserve Program, which removed about 36 million acres of marginal farmland from agricultural production and enhanced its value as food and cover for wildlife; to assess impacts of habitat fragmentation on grassland birds, which include waterfowl; to contain the spread of invasive weeds; to assess the ecological functions of natural and restored prairie wetlands; to determine the effect of agricultural practices upon sedimentation and chemical contamination of prairie wetlands (fig. 4); to determine predation rates on grassland birds and to document the ecology of their mammalian predators; to determine survival rates and causes of mortality of waterfowl broods; and to develop methods to inventory amphibians and nocturnal wetland birds.
