The Bastrop County Complex fire was a conflagration that engulfed parts of Bastrop County, Texas, in September and October 2011. The wildfire was the costliest and most destructive wildfire in Texas history and among the costliest in U.S. history, destroying 1,696 structures and causing an estimated $350 million in insured property damage. An exceptional drought, accompanied by record-high temperatures, affected Texas for much of 2011. Vegetation consequently became severely parched throughout the state, and over the year an unprecedented amount of land in the state was burned by numerous wildfires. In early September 2011, the presence of Tropical Storm Lee to the east produced strong northerly winds over the state, exacerbating the preexisting dry weather to produce critical fire conditions. On the afternoon of September 4, 2011, three separate fires ignited in the wildland–urban interface east of Bastrop, Texas, after strong winds caused by the nearby tropical storm snapped trees onto power lines. Within 48 hours, the fires merged into one blaze that quickly consumed parts of Bastrop State Park and parts of the Lost Pines Forest, as well as homes in nearby subdivisions. Most of the conflagration's spread and destruction occurred within a week of ignition, as the forward advance of the wildfire mostly stopped after September 7. The wildfire was largely contained in September, though the firebreak was briefly breached in early October. On October 10, the Bastrop County Complex was declared controlled, and the fire was declared extinguished on October 29 after 55 days of burning within the fire perimeter.
