  Marble Falls Arpt, Burnet County

  $30M damage

  What happened

  Heavy rain mainly west of Burnet County and lakes LBJ and Marble Falls, caused rapid rises on the Colorado River. Several hundred thousand CFS of flood water entered Lake LBJ near Kingsland (where the Llano River enters the lake), with flood waters flowing down the Colorado River into Lake Marble Falls. Lake LBJ and Marble Falls rose rapidly, flooding homes and some businesses. While the lake only rose a few feet at Wirtz Dam, farther upstream on Lake LBJ near Kingsland, Granite Shoals, Highland Haven, and Cottonwood shores, rapid rises on the Lake caused many homes to flood. Lake LBJ started to rise in the predawn hours and continued high through the day. Downstream of Wirtz dam is Lake Marble Falls which saw a 15 feet rise in less than 12 hours. Evacuation notices were sent out near the Lake on the morning of Oct 16. For the above mentioned communities, estimates of damage include 17 homes destroyed, 168 with Major damage, 64 homes with Minor Damage, and 31 homes that were affected. As of this writing, early and ongoing flood insurance payouts totaled over 11 million dollars so far along with roughly 7 million spend on debris removal and 2 million dollars worth of...

  What happened

  Heavy rain from slow-moving thunderstorms fell into the Hamilton Creek watershed contributing to a rapid rise of the creek that moved downstream near Marble Falls into the Colorado River. While only 1 to 2 inches of rain fell over Marble Falls, a swath of over 10 inches of rain occurred within the watershed upstream. An LCRA stream gauge on Hamilton Creek near Marble Falls measured a rise of 18.65 ft in about 90 minutes with 49,970 cfs before the gauge stopped reporting data. Widespread inundation and downing of trees occurred along the Hamilton Creek, with the extent of inundation at times nearly 1/3 mile across near FM 1431. The CR 341 crossing along Hamilton Creek was completely washed out on both approaches, leaving only a significantly damaged central concrete segment. The south approach to the CR 340/Mormon Hill Rd crossing was scoured out by floodwaters. Several homes were flooded along Hamilton Creek Rd. farther downstream of the CR 341 crossing. The Cedar Stays RV Park, located along the creek near FM 1431, saw major impacts. About 50 RVs were parked there overnight. All RVs were impacted by flooding and most were total losses.
