Because little or no surface water is available in the area, an extensive hydraulic system was created at Calakmul, including 13 large reservoirs with a minimum total capacity of nearly 100 million liters. Canals carry water to and from the reservoirs and at least seven sacbe or sacbeob (causeways) have been mapped to and from Calakmul. Calakmul battled with recurring droughts; and it is believed that an extended drought between AD750 and 950 contributed to the city's collapse.
