摘要：	After a two-month closure, which was bisected by a week-and-a-half-long opening to navigation in October, Lindy C. Boggs Lock, the southernmost lock on the Red River, resumed operations November 12 at 7 p.m. Boggs Lock, also known as Lock 1 on the J. Bennett Johnston Waterway, closed to navigation August 30 for a routine maintenance dewatering. The closure coincided with a dewatering at Old River Lock on the Mississippi River. Old River Lock received new Mississippi-side miter gate leafs and expansion joint repairs throughout. The two locks were originally planned to both reopen on November 12 but work at Old River wrapped up a week ahead of schedule. Over the past month, as drought conditions worsened across the region and as the Mississippi River dropped lower and lower, Red River stakeholders became increasingly concerned that the available draft of the navigation channel below Lock 1, often referred to as "the gauntlet," would drop below the authorized 9 feet. Fortunately, rain in the region and coordinated reservoir releases upriver into the Mississippi have translated into higher stages on the lowermost portion of the Red.
