This work brings a balance between supply and water demand for irrigation by central pivots in Goiás. The analysis considered the facilities of Goiás and the Distrito Federal in 2013. The water availability considered were the granted volume for each month of the year in Goiás: 50% of Q95%.To calculate the demand were used the procedures defined in the Technical Manual for the Granting of SEMARH. In this context, it was delimited 9,542 sub-basins of which 2,850 has demand in 2013, of which 543 had demand superior to the granted volume. It was observed that the period that presented the highest demand was between April and September, figuring this last month as the most critical. Eight areas that showed high levels of commitment were mapped, especially in the Upper and Middle Paranaíba, Middle River Araguaia and Upper River Uru, beyond the River Preto basin's, predominantly in the Distrito Federal.
