The Nebraska Dam Inventory is maintained by the Nebraska Department of Natural Resources. The inventory is submitted annually to the National Inventory of Dams. The Nebraska Dam Inventory is available for viewing in two formats, either through the Interactive Map for Dams or through the Nebraska Dam Inventory Database. The Nebraska Dam Inventory includes all dams in Nebraska that are 25 feet or more in height or have a maximum storage capacity of 50 acre-feet or more. The inventory includes dams that are currently existing, have been approved for construction, or have breached.
