In late 1970 the construction of two reservoirs was approved in the National Hydrological Plan of Cordobilla de Lácara along the Rio Lácara and one of its tributaries. These reservoirs, Embalse de Horno Tejero and Embalse del Boquerón, opened in 1985. These projects have changed the original landscape; they appear as two large lakes in the midst of the pastures nearby. The reservoirs provide water to the Commonwealth of the Northern Lácara, of which Lácara Cordobilla is a part. They are not navigable and bathing is prohibited. The main fish are carp, pike and black bass.
