Temperatures recorded indicated that 1954 to 1956, 1986 to 1988, and 2004 to 2006 have the highest amount of temperature variance. Average annual temperatures (JPEG) have proven to be particularly erratic throughout central Texas and the Blanco River Basin (USNCDC 2013). A general trend of increasing annual temperatures proves future concerns with water security in this sensitive environment.

Higher temperatures increase the impacts of drought and cause abnormal amounts of evapotranspiration, affecting ground and surface water supplies.
