CETRAD runs a rich hydromet data and information base generated from its long term and comprehensive monitoring network in the upper Ewaso Ngiro North river basin. Most of this data is now linked through a real time transmission system and interfaced to its database as well as to some selected Water Resources Users Associations (WRUAs) in the upstream areas.
