TexMesonet
In response to the devastating Memorial Day Flooding in the Blanco River Basin in 2015, the Office of the Governor and the Texas Water Development Board (TWDB) executed a Memorandum of Understanding providing funding from the Disaster Contingency Account 0453 to support activities related to flood notification systems and floodplain management planning. The TexMesonet program was established in 2016 to provide near real-time hydrometeorological observations to support flood response. In 2023, the 88th Texas Legislature added §16.012 (7-a) and §16.028 to the Texas Water Code that designate the Texas Water Development Board as being responsible for establishing a hydrometeorological data collection and dissemination network.
TexMesonet operates as a “network of networks” by establishing a unifying architecture for mesonets across Texas and aggregating data into a central online location. Data is collected from national, regional, and specialized networks, such as those operated by the National Weather Service, U.S. Forest Service, the Federal Aviation Authority, Lower Colorado River Authority, West Texas Mesonet, Guadalupe Blanco River Authority, and other local entities. Since its inception in 2016, the network has grown to include 126 TWDB stations and more than 3,000 partner stations. The TWDB continues to strategically add additional stations to improve statewide coverage.
