Houston photographer Jim Olive took this photo of Barker Dam and Reservoir in west Houston on Sunday, June 5, at around 11:30 a.m.
The dam gates had just been opened, and water from recent rains was pouring from the reservoir’s temporary lake into Buffalo Bayou, which flows through Barker Reservoir through the center of Houston and into Galveston Bay. Water impounded from several creeks behind nearby Addicks Dam also flows into Buffalo Bayou below Barker Dam. The dams were built in the 1940s to protect downtown Houston from catastrophic flooding.
Record rains that fell on west Houston and elsewhere on April 18 filled the two flood control reservoirs with unprecedented amounts of water. Rains since then have slowed releases from the normally empty basins, which contain large, forested parks and recreational facilities. The Army Corps of Engineers, which owns and operates the dams, closes the dam gates during a rain, and rain adds more water to the reservoirs, which must be emptied as quickly as possible in order to create room to hold back future stormwater. Maximum capacity, the volume beyond which water will begin to spill around the ends of the dams, is 199,643 acre-feet for Addicks and 209,600 acre-feet for Barker. Addicks Reservoir is just to the north of Barker on the northern side of Interstate 10.
The combined peak pool behind the two reservoirs was more than 206,000 acre-feet around April 22, with Addicks reaching some 122,000 acre-feet or a little more than two-thirds of maximum capacity. Despite record high extended releases from the dams for the last seven weeks, the two reservoirs have been drained by less than half, standing at a combined volume of 114,210 acre-feet on Tuesday early afternoon.
