The Dona Francisca Hydroelectric Dam impounds the upper Jacuí River, and is divided between the municipalities of Agudo and Nova Palma, Rio Grande do Sul.[2] The Quarta Colônia State Park is on the left bank of the reservoir of the Dona Francisca dam, with an area of 1,847.9 hectares (4,566 acres). The park was created in 2005 as environmental compensation for the hydroelectric plant.[3]
