Siccità in Texas

Texas State Park police officer Thomas Bigham reaches down into what remains of O.C. Fisher Lake Wednesday, Aug. 3, 2011, in San Angelo, Texas. A bacteria called Chromatiaceae has turned the 1-to-2 acres of lake water remaining the color red. A combination of the long periods of 100 plus degree days and the lack of rain in the drought -stricken region has dried up the lake that once spanned over 5400 acres. (AP Photo/Tony Gutierrez)
