Complementary Law No. 121 establishing the Maranhão River Water Reserve.

This Complementary Law establishes the Water Reserve of the Maranhão River within the territory of the Federal District, with the primary objective of safeguarding the hydrological resources of its basin. The law aims to ensure the preservation of water potential and to secure the availability of potable water, recognizing water resources as strategic assets for environmental sustainability and human consumption. In addition, it supports the sustainable use of the area by promoting activities such as ecotourism and fishing, provided these are compatible with the conservation of the ecosystem. Furthermore, the law sets out the basis for the implementation and management of the reserve through planning, coordination, and scientific assessment. It requires the establishment of preservation guidelines, the development of socio‑economic and environmental studies, and the formulation of coordinated action programmes involving public authorities and stakeholders. The law also emphasizes intergovernmental cooperation—particularly with federal and Goiás state authorities—and provides for public participation through hearings, ensuring that the management of the reserve integrates environmental protection with sustainable development and resource use objectives.
