Proper utilization of available water resources and implementation of development plans requires an accurate database and updating of statistical and meteorological information. The process of measuring meteorological data until it is recorded in a database is an accurate, sensitive and time-consuming process. This study examines the country's meteorological network, which is managed under the supervision of the Ministry of Energy, and the pathology of the current state of meteorological measurements. Accordingly, network evaluation was performed in three major sections: network status evaluation in terms of statistics and field visits and evaluation of the measurement trustee. The survey of measurement system administrators varies around the world, and the focus of measurement varies from ministry to ministry, depending on the macro goals of water and water productivity in each country. A study of the statistics of the country's measurement network showed that one of the most important problems is the lack of stations in the highlands and the lack of a long-term statistical period. Although the construction of the stations is more than half a century old, proper management over time has not been able to observe a proper network. Field evaluation of meteorological stations in the country also showed that the lack of attention to the necessary equipment and infrastructure, the cost of the measurement process, lack of culture regarding the need for measurement, managers' inattention to the measurement process and etc. have been caused that the quality and quantity of measurements are affected. Establishing a proper monitoring network, although it has high initial costs, but the return on investment is necessary and important due to the necessity of statistics and information to implement any development plan.
