Recorded climate data shows the extreme nature of temperature and precipitation in the basin that is not accurately displayed by simply averaging data.
An average of annual precipitation values over the last 50 years can be determined using data from Blanco weather station 410832 (Figures 10 (JPEG) and 11 (JPEG)). Data analysis shows that the highest amount of precipitation was recorded in 2004-2005.
With increasing average annual temperatures, and decreasing precipitation rates, continued stresses on central Texas’ water supply magnify the current and future impacts of drought in the Blanco River Basin.
In addition to the impacts of drought, this region can experience common flooding. Such impacts have lead to the adaptations you see in many aquatic species. Despite current flood managing dams built to mitigate the impacts of such floods, flood condition in and around the Blanco River remain a concern for residence and their property.
