Description: This dataset contains the State of Florida subset of the 2025 National Inventory of Dams (NID). The NID is a congressionally authorized database, which documents dams in the U.S. and its territories. The NID is maintained and published by USACE, in cooperation with the Association of State Dam Safety Officials (ASDSO), the states and territories, and federal dam-regulating agencies. The database contains information about the dam’s location, size, purpose, type, last inspection, regulatory facts, and other technical data. Prior to 2021, the U.S. Army Corps of Engineers (USACE) updated the NID, annually, with information provided by states and federal dam regulating agencies across the nation. Starting in November 2021, state and federal dam safety regulatory entities can enter data directly and as often as they like or provide bulk data updates directly to USACE. This change provides flexibility and supports access to real-time, up-to-date information for the more than 91,000 dams in the NID. The dams in the NID are owned, operated, or regulated by a variety of entities. About 75 percent of the dams in the NID are regulated by the state dam safety offices, and almost 70 percent of the entire inventory is privately-owned dams. The federal government owns or regulates five percent of dams in the NID, which includes approximately 55 percent of the tallest dams. Dams located in Florida that are listed in the NID meet at least one of the following four criteria: 1) High Hazard Potential dams - Loss of human life is likely if the dam fails. 2) Significant Hazard Potential dams - No probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities or other impacts. 3) The dam is equal to or exceeds 25 feet in height and exceeds 15 acre-feet in storage. 4) The dam exceeds six feet in height and is equal to or exceeds 50 acre-feet in storage. USACE manages the NID but does not own most of the dams in the NID. Operation, maintenance, and repair of these dams is the responsibility of each dam owner. Please contact the respective state or federal regulatory authority for the most up-to-date information. This layer is an update to the FGDL layer USACE_DAMS_2019.
