 Hydrologic Unit Code Level 4 Boundaries (2002)
This dataset contains 1:250,000-scale hydrologic unit code level 4 boundaries for those cataloging units comprising the Northeast Wyoming River Basins Planning Area - this dataset is clipped to the planning area. 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 USGS Office of Water Data Coordination, together with the list descriptions and name of region, subregion, accounting units, and cataloging units. 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. Some areas, notably major cities in the west, were recompiled at a scale of 1:100,000. In order to join the data together and use the data in a geographic information system (GIS) that data were processed in the ARC/INFO GIS software package. Within the GIS, the data were edgematched and the neatline boundaries between maps were removed to create a single data sest for the conterminous United States.

 Irrigated Lands (2002)
This dataset contains the irrigated lands mapped for the Northeast Wyoming River Basins Plan. All man induced irrigation or subirrigation was delineated. Natural subirrigated fields were not delineated unless some benefit was being received from a man made system. Irrigated lands were divided into the following categories based on visual interpretations of the quality of the irrigation, types of crops supported, and the type and condition of the irrigation delivery systems and on-farm systems used to serve these lands: A - Full service irrigation (typically receives a full water supply); B - Partial service irrigation (typically receives a reduced water supply due to limited water availability or the inability to provide complete field coverage); C - Man induced subirrigation (beneficial use resulting from incidental irrigation such as ditch seepage to areas below a canal); E - Idle irrigation (lands not currently receiving water, typically due to nonfunctional delivery facilities); S - Spreader dike irrigation (dikes constructed across ephemeral streams to spread infrequent flows over the land to increase beneficial use); H - Minor beneficial use (lands that receive some beneficial use on occasion such as lands served by "kick-out" ditches on ephemeral streams); AD, BD, and ED - A, B, or E lands that have undergone or are currently undergoing residential development.

 Major Reservoirs (2002)
This dataset contains the 6 major reservoirs in the Northeast Wyoming River Basins Planning Area. All surface water storage in structures containing more than 50 acre-feet of storage or more than 20 feet high (meeting the minimum standards for inclusion in the Dam Safety database) were initially selected. These selection criteria produced a set of 209 surface water storage facilities. The State Engineer's Office Water Division Two commissioners agreed that a further set of criteria should be introduced to provide a list from which the dams of particular significance to the basin could be developed. Commissioners agreed that in almost all cases, a limit of 1,000 acre-feet capacity and "serving multiple users" produced a list of reservoirs significant to the basins, reducing the secondary selection list to 6. This dataset shows the locations of the 6 significant reservoirs and, with the complementary Major Reservoirs Water Rights dataset (a dbase table), contains the pertinent water rights and storage information for each reservoir.
