However, not all countries are comfortable with this information system being developed and centrally situated in another country. After 1991, hydrological monitoring drastically decreased. For example, on the Chu and its tributaries, the number of hydrological monitoring stations has decreased by more than two thirds since the 1970s. Similarly, of some 100 hydrological monitoring stations on Kyrgyz territory within the Syr Darya Basin in 1980, currently 28 are operational.
