The La Laguna is short for La Comarca de la Laguna (the region of the lake) or Comarca Lagunera (region of lakes), an arid and semi-arid region that covers a significant portion of northeastern Durango and southeastern Coahuila. The area was created by sediments from torrential river flows deposited over large valleys. These river flows also created lagoons which served to recharge underground aquifers or remain as intermittent surface waters. Originally, the rivers supported habitat for native grasses, rush and ditch reed which provided habitat for various water birds and fish.
