 Bear River Basin Boundary (1994)
The Geographic Information Retrieval and Analysis System (GIRAS) was developed in the mid 70s to put into digital form a number of data layers which were of interest to the USGS. One of these data layers was the Hydrologic Units. The map is based on the Hydrologic Unit Maps published by the U.S. Geological Survey Office of Water Data Coordination, together with the list descriptions and name of region, subregion, accounting units, and cataloging unit. The hydrologic units are encoded with an eight- digit number that indicates the hydrologic region (first two digits), hydrologic subregion (second two digits), accounting unit (third two digits), and cataloging unit (fourth two digits). The data produced by GIRAS was originally collected at a scale of 1:250,000. This data set is a modification for Wyoming of the original United States HUC data produced by the USGS. The primary modifications made in this data set by the Wyoming Water Resources Center include 1) removal of hydrologic units that do not drain witi Wyoming and 2) modification of the hydrologic unit boundaries to better encompass streams and lakes represented in the 1:100,000 scale Digital Line Graph (DLG) of surficial hydrography. The HUC boundaries have not been "clipped" to the Wyoming border, in order to maintain the natural boundaries of the units. This metadata has also been altered from original USGS metadata to be more specific for Wyoming.

 Irrigated Land (1999)
This data set is a polygon coverage. It only contains irrigated acreage in the Bear River Basin within or near Wyoming. The interpretation of irrigated lands due to the works of man was taken from 1982 and 1983 aerial infra-red photos. Upon completion of digitizing these areas, Wyoming State Engineer's Office field personnel updated the lands and checked the accuracy of the delineation. Their check was completed in the fall of 1998. The data structure for thi data set is based on graph theory, in which a two-dimensional diagram is expressed as a set of spatial objects in a manner that explicitly expresses logical relationships. Applied to a map, this concept is used to encode the spatial relationships between the objects, including such concepts as adjacency and connectivity between objects. A topologically structured data file can support graphic applications, as well as computations and analyses involving the spatial objects and their spatial relationships.
