The dam was completed in 1950, and it was built to mitigate flooding in Murfreesboro and to provide hydropower. The 941' (287m) long dam rises 183.5' (56m) above the river. "The powerhouse of the dam is located adjacent to the east abutment and has three 8,500-kilowatt-hour (KWh) [should be kw instead of kwh] generating machines, the third one having been installed in 1969. The average power annually generated is 28,000,000 KWh. Its maximum discharge is 42,300 cubic feet per second." The spillway has been used in 1968 and 2009. "Each time, the areas below the dam along the river were flooded, but not nearly as badly as in the days before the dam was built." [encyclopediaofarkansas]

"The U.S. Army Corps of Engineers, during recent maintenance activities on the trash racks at Narrows Dam at Lake Greeson, Arkansas, identified a need for repairs to the metal structure supporting the trash racks. Trash racks are metal grates preventing large debris from entering and damaging the turbans used for creating hydropower, and do not affect the integrity or effectiveness of Narrows Dam."

| ArkansasOnline, May 2009 file photo. (Arkansas Democrat-Gazette file photo) To put the 28 million kWh production of this dam in perspective, the "Arkansas Nuclear One near Russellville produced 13.55 billion kWh in 2021." |
Over one year after they stopped generating power because of a defective trash rack support, they are going to repair the dam. I presume it is the trash rack support that they are fixing.
