Remmel: (Satellite) The downstream dam.

1923 Remmel Dam creates Lake Catherine, and 1932 Carpenter Dam creates Lake Hamilton. The dams were built by Arkansas Power & Light. Remmel Dam was the first major generating facility in Arkansas. The 2003-2053 license requires a minimum continuous release of 200-400 cfs, depending on the month of the year, from the Remmel Dam. This makes fish and canoers happier. "For the benefit of lakefront property residents, Entergy has agreed to limit the amount of daily lake level fluctuations to 24 inches on Lake Catherine and 12 inches on Lake Hamilton and to consult with the AGFC on annual lake drawdowns. For the benefit of whitewater enthusiasts, the license calls for “full generation flow” three hours each Saturday and Sunday afternoon Memorial Day weekend through Labor Day weekend. In addition, there will be up to four special releases annually to accommodate emergency training exercises and other education-oriented events." [entergy_license]

| entergy_operations The Winter water level is about 5' (1.5m) lower than the Summer water level. |
I presume the current turbines can't operate at the minimum required flows and that is why it is common to see one gate spilling. Although, given the clouds in the background, this spilling may be to accommodate rainfall given the strict lake level requirements for recreational use.
