Description:
Abstract:

The DNR in cooperation with NRCS, USGS. DEQ, DWR, and NGP delineated and computerized the boundaries of drainage areas that formed the basic hydrologic units needed for water resources planning and other uses. These basic hydrologic units were designed so they could be aggregated to many combinations of watershed or river basins. The DNR also digitized the major stream in each watershed. This documentation describes the digitized streams. They have been integrated into the DNR's computer data systems so they are available to all with the facilities to access the Natural Resources Data Bank.

Purpose:
Section 2-15,100 of the Nebraska statutes gives the DNR responsibility for conducting the State Water Planning and Review Process. The statutory purpose of the planning process is to coordinate and direct the planning efforts of the state agencies and the university divisions with responsibilities and interest in the water resources field. The statutes add that the process shall be designed to, amon other things, develop and maintain the data, information, and analytical capabilities necessary to provide state agencies and other water interests with a support basse for water planning and management activities. The digitized streams and related basic hydrologic units are an important part of the hydrologic section of that information support base.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Most of the original data was digitized from 7 1/2 quad maps where they were available. This digitized information was processed on a PC with a series of FORTRAN programs and then plotted at 100% scale and overlayed on the original to verify the accuracy. Many checks were programmed into the FORTRAN programs to help correct or identify inaccuracies. Other error checking and correcting was accomplished using visual inspection, Paradox 3.0 and Arc/Info 6.0 and later Arc/Info 7.0.
Logical_Consistency_Report:
The stream codes were checked against a list of valid codes through a FORTRAN program on a PC. Additional checks were made on an Arc/Info workstation. All codes were valid. Maps were generated and a 100% visual check was approved. All data was checked several times through several error checking programs in Arc/Info 6.0 and 7.0 to determine if there were any streams were not associated with their appropriate hydrologic unit.
Completeness_Report:
In most cases the information was digitized from 7 1/2 USGS quadrangle maps. In areas were they were not complete or we did not have them, other maps were used such as the 15-minute series in Nebraska and the 1:250,000 and 1:500,000 series maps in areas of the states bordering Nebraska.

Process_Description:
Basic Hydrologic Units (BHUs) are the drainage areas of the smallest units in the DNR system. They are subdivisions of the areas in the systems of six state and federal agencies: the DNR, Department of Environmental Quality (DEQ), Game and Parks Commission (GPC), U.S. Geological Survey (USGS), and Soil Conservation Service (SCS). They were created by dividing all streams essential to those systems at all the division points in those systems. All points such as stream gages (DWR and USGS), end points of water quality stream segments (DEQ), and fisheries stream segments (GPC), basin and subbasin boundaries (DNR and USGS), hydrologic units (USGS), and watershed boundaries (SCS) were used to divide the essential streams to create elemental stream reaches that could be added together in different combinations to duplicate any of those systems. Delineating the drainage area of these elemental stream reaches produced the smallest subdivisions of the drainage areas used by those agencies. Therefore, basic units can be aggregated to any of their watersheds or basins.

Attribute_Domain_Values:
Enumerated_Domain:
Enumerated_Domain_Value: A six-digit number (STR-ID) was assigned to identify each BHU. The six-digit number was comprised of 3 sets of two-digit numbers. The first two digits identify the river basins as defined by state statutes and range from 01 to 13. The second set of two-digit numbers identifies the division and ranges from 01 to 17 and the third identifies the BHU and ranges from 01 to 99.
Enumerated_Domain_Value_Definition:
Nebraska is officially divided into 13 river basins so the numbers in the first set range from 01 to 13. The basins are numbered in upstream order from the Missouri River. For example, water flowing from the Big Blue River is the most downstream and is numbered 01, while the White River-Hat Creek basin water flows north into South Dakota and into the Missouri River so is numbered 13. Each river basin has been subdivided into the drainage areas of the major streams in the basin. The Little Blue and the South Platte river basins have as few as four divisions while the Republican River Basin has 17. Consequently, the second group of two-digit numbers range from 01 to 17 for each river basin numbered in upstream order. The last two-digit number further subdivides the major stream divisions into the BHU. These numbers range from 01 to 99. Although these last two digits were originally numbered in upstream order, revisions made during the delineation, digitization, processing, and verification processes and subsequent updates required that basic unit numbers sometimes be added or removed. As a result, these numbers are no longer necessarily in upstream order.
