STUFF YOU PROBABLY SHOULD KNOW ABOUT THE ADDICKS AND BARKER RESERVOIRS Lived in Houston for years but still coming up to speed on how the Addicks and Barker dams are supposed to work — just as the reservoirs reach to their highest-ever levels? This brief explainer from Kiah Collier and Neena Satija of The Texas Tribune Al Shaw and Lisa Song of ProPublica should overfill you with info: “As of now, the Army Corps says there’s enough excess water in the reservoirs that some of it will flow around (not overtop) these auxiliary spillways. . . . The Army Corps can’t say exactly what areas might experience additional flooding, but local officials listed 53 subdivisions in the Addicks watershed and 40 in the Barker watershed (shown in brown in the map above) at high risk of flooding. Jeremy Justice, a hydrologic analyst at the Harris County Flood Control District, said two subdivisions near the Addicks reservoir—Twin Lakes and Lakes On Eldridge—are particularly vulnerable to flooding from the Addicks spillway. Those homes ‘probably should never have been put there,‘ he said.” Thousands of homes around the reservoirs have now flooded — some because they’re close to rising bayous, and some because of bad neighborhood drainage, they write. “But many are flooding because they are in an area that the Army Corps actually considers to be inside the reservoirs.
