The Senguer River has its source in Lake Fontana on the Andes and then flows into Lake Muster and later into Lake Colhué Huapi, providing water through channels to the fertile Sarmiento Valley. Therefore, this hydric chain is of vital importance for the water supply to Sarmiento and the city of Comodoro Rivadavia.
Lakes Muster and Colhué Huapi are suitable for water sports and fishing. There are two small tourist complexes here.
