The management of water resources involves an analysis of the biotic, abiotic and anthropogenic resources that are part of the basic unit of an area of the river basin. This is a hydric unit, territorial and rural, that can be seen as a kind of protection of the water bodies, to the detriment of the quality and quantity of its waters. The study of land use and occupation is not done with water bodies, especially if assisted by remote sensing tools, is essential for the study of their environmental preservation of water resources, an end of action anthropic action that acts on these resources, are finite. In relation to the reality of the northeastern semi-arid, a situation becomes more delicate for the greater scarcity of resources, while the scarce rainfall levels of the region and its smaller local storage capacity. This context, arises the issue of the governance, the policies of governance of the governances and the organized, institutional and regulatoryations to that related. The Pereira de Miranda dam, located in the Curu basin, was built in 1957 by DNOCS, with a capacity of 395 hm³ at the time. A report of this work has been reviewed for the current situation of the reservoir. The mapping of land use and occupation in the region of the margins and the work environment was carried out using the GIS (Geographic Information System) and images of the LANDSAT 8 satellite, which, together with the information collection in the literature and with its users and the civil society sectors associated with the Pereira de Miranda risk, the power of an opinion on this situation. The results were compared with data and information on the quality and quantity of water in the water, including environmental impact such as eutrophication and silting. It was verified that the use and the occupation of the soil in the margins and the surroundings of the company Pereira de Miranda present at present inadequate conditions. In addition, they checked the pending drafts of the Municipal Master Plan and the Municipal Basic Sanitation Plan, which may aggravate a demilitarized situation.
