National Levee Database Centerlines

The National Levee Database is a Congressionally authorized database that documents levees in the United States. The NLD is maintained and published by the U.S. Army Corps of Engineers (USACE).The NLD contains information about the condition and risk information for approximately 2,000 levee systems (approximately 15,000 miles/mostly levees affiliated with USACE programs. An additional 6,000 levee systems--approximately 15,000 miles--have location information, but little to no information about condition and risk. One of the goals for the NLD is to include data about levees owned and operated by all other federal agencies, tribes, states, municipalities, levee boards, and private entities. This information will be added as it becomes available. United State Army Corps of Engineers NLD mission statement.The full NLD as an AGOL Feature Layer.
