Due to the abnormally high drought conditions, the Lower Colorado River Authority (LCRA) has produced a webpage specifically covering the topic. The site contains comparative historical data and details on the current conditions. As of August 16, 2011, the map on the site shows that, with just a few exceptions, the entire state of Texas is suffering in Exceptional Drought Conditions, the most severe category on the scale.
According to the website, the ten months from October 2010 through July 2011 made up the driest period of that length since record keeping began in 1895. But it is still not the worst drought on record. A drought lasting 10 years in the 1940s – 50s was the worst in recorded history.
The website also provides information about boat ramp closures and lake depths for Lake Travis and Lake Buchanan. As of August 1, 2011 Lake Travis is 26 feet below the monthly average depth and is predicted to continue to drop.
