20 feet in one hour. Insured losses were estimated at around $100 million. Overall in Hays County, including Wimberley and San Marcos, 321 homes were destroyed, with hundreds more heavily damaged. During the May 24 event, the river crested at 36.52 ft at Kyle, Texas, which was (at the time) the highest the river had been since a 40.0 ft crest in 1929. Kyle is downstream of the Wimberley gauge. On October 30, 2015, the river flooded again. The river crested at 37.24 ft at Kyle, exceeding the gauge height of the May 24, 2015 crest, becoming the highest the river had been since a 40.0 ft crest in 1929. The Wimberley gauge had a crest of 26.54 ft on October 30, 2015. Flooding near San Marcos led to closure of the Interstate 35 bridge over the Blanco River for the second time in 2015. Geography The upper reaches of the Blanco River are hilly, and the river's slopes are frequently steep. As the river reaches the Balcones Escarpment near San Marcos, it widens and its slopes moderate; this is typical of rivers in the central part of the state. Economy The Blanco River provides drinking water for the city of Blanco, as well as water supplies for nearby ranches. The river also supports a number of recreational areas, including the Blanco State Recreation Area in Blanco, the former Boy Scouts camp El Rancho Cima near Wimberley, and other private parks and resorts.
