Water is a crucial resource and approximately 70% usage of it in the agriculture sector in Turkey. Water user associations are in charge of irrigation water management. The core aim of this study is to assess water user associations have command area more than 1,000 ha (WUAs) within the districts of DSI (State Hydraulic Works) and to create spatial maps to show the distribution of the performance indicators used constantly by researchers especially around Mediterranean countries during the period from 2011 to 2015. Frequency and panel data analysis are used to figure out the relationship among performance indicators and attributes such as water diversion type, management type, source of water and district no. Panel data analysis was applied to examine statistical assessment over time. As a result, current performance indicators show that excessive irrigation water used due to low technology and management problem. Performance indicators show high differences among districts due to climate, water resources, and crop pattern. Moreover, low irrigation efficiency can be increased with a transition to pressurized irrigation systems, so more are can be irrigated with less water.
