Flooding in Junction and Mason is a sign of what's expected in Llano County where the Llano River is in a major flood stage.
The City of Llano says it is preparing for the river to swell higher than it's been at in more than a decade.
The Llano River could climb above 20 feet depending on how much water spreads as it moves downstream.
Originally officials predicted the water would reach Llano at around 6 a.m. Tuesday but it happened late last night.
The Lower Colorado River Authority has opened floodgates at Lake LBJ and the Starcke Dam to help alleviate any downstream flooding.
All low water crossings in the city of Llano are expected to be closed for the next several days.
Officials urge people to not get too close to the river since the water is rising rapidly.
Lake Travis is also expected to rise between two to three feet over the next few days. Emergency crews are standing by if any problems occur.
