As of March 2025, RATES has installed over 60 RATES-designed Real-Tiem Hydrolgic Stations (RTHS) throughout the Lower Rio Grande Valley (Texas). Installation and operation of these stations was/is supported by a variety of sources, including Texas Water Development Board (TWDB) Freshwater Flows, TWDB Flood Infrastruce Fund projects administered by the Lower Rio Grande Valley Council of Governments (LRGVDC) and the City of Harlingen, Texas Commission on Environmental Quality (TCEQ) 319 programs, the Environmental Protection Agency (EPA) funded Norh American Development Bank (NADBank) Border 2025 program, and assorted local municipalities. Stations continuously monitor, at minumim, water level and water temperature; where applicable, rating curves are being developed for converting water level into discharge. Stations TWDB1, TWDB2, and TWDB3 are presently recording continuous water quality data for various parmameters using In-Siutu brand sondes as part of TCEQ-funded watershed characterizaion activities.
