For de study case system of Patu, located in Senador Pompeu, in the backwoods of Ceará, were defined four drought states, normality, pre warning, warning and emergency. Starting from it were compiled measures presents in five Drought Plans of other countries, being four Spanish plans and one American, choosing actions that were related to Patu system, dividing them into six categories presents in all dry states and that were applied in other systems in the region. In total were collected 83 indicators to four drought stages, were also chosen 14 indicators for future events, in order to analyze the effectiveness of steps taken and follow how the system responds after a lack of water event
