The Hope Mills Dam, also known as Hope Mills Dam #1, is a failed concrete gravity dam on Little Rockfish Creek in Hope Mills, North Carolina, USA, which created Hope Mills Lake. Three different dams were built on the site including the current one. The first dam, of rock-crib design, was built in 1839 to power local cotton mills. The second was an embankment dam built in 1924 for powering the mills and later to maintain the lake's water level. Both previous dams failed from flooding. The current dam failed in June 2010 after a leak was discovered and the lake was drained.
