The dams inventory database includes all dams which have minimum height of 6 feet and exceed a storage capacity of 50 acre feet, or have minimum height of 25 feet and exceed a storage capacity of 15 acre feet or have a "high" or "significant" hazard classification. The data also describes the type of dam, the completion date, the dam height and length, the county the dam is located in and various other informative data. This data can also be retrieved by county, owner, dam identification number, township and range or varies other purposes.
This dam inventory data can be used as a digital layer in various studies.

The values of the attributes are collected from the engineering plans by the Nebraska Department of Natural Resources.
The engineering plans are checked for accuracy during the initial inspection of the dam.
Every year the Nebraska Department of Natural Resources submits a copy of the dam inventory report to the Corps of Engineers and any questions about the data are updated at that time.
