Rincón del Bonete Lake
The Rincón del Bonete Lake is the largest body of fresh water in Uruguay. It is located in the middle of the country in the south part of Tacuarembó Department with a small part of it reaching into the north part of Durazno Department. Rincón del Bonete is an artificial lake formed by a dam on the course of Río Negro. It was built in 1945 and has a surface of about . The dam was overtopping during the 1959 floods, and the hydroelectric facilities damaged. The riverine tug "Don Pancho" was assigned to the transport of  building materials and supplies from Salto during the construction of the dam, between 1937 and 1946. She was later used to evacuate local residents in the course of the 1959 floods. The vessel was eventually converted into a patrol boat. "Don Pancho" sank in the waters of the lake in January 2016 though she was raised a few days later.
