The Rio do Peixe State Park is divided between the municipalities of Dracena, Ouro Verde, Piquerobi and Presidente Venceslau, São Paulo.

[1] The park would be part of the proposed Trinational Biodiversity Corridor, which aims to provide forest connections between conservation units in Brazil, Paraguay and Argentina in the Upper Paraná ecoregion.

[2] The park protects the margins of the Rio do Peixe, a left tributary of the Paraná River, in a region near its mouth where it meanders through várzea interspersed with permanent or temporary lagoons.

It was created as partial compensation for the land flooded by the Companhia Energética de São Paulo (CESP) with the Engenheiro Sérgio Motta Hydroelectric Power Plant on the Paraná River, which would flood 13,227 hectares (32,680 acres) of the Lagoa São Paulo Reserve and 3,211 hectares (7,930 acres) of the Great Pontal Reserve.

[7] On 9 June 2016 State Governor Geraldo Alckmin and Secretary of the Environment Patricia Iglecias attended a ceremony to plant seedlings of native Atlantic Forest trees as part of the project to restore a 245 hectares (610 acres) area of the park.
