The water in dams
A dam is a barrier that impounds water or underground streams. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. Hydropower and pumped-storage hydroelectricity are often used in conjunction with dams to generate electricity. A dam can also be used to collect water or for storage of water which can be evenly distributed between locations.
Reflection about the consequences of human activity in care and water activity
It’s so important to check out our diary activity because everything we do has a bad effect in our environment, maybe we can’t see it directly but the damage is growing up very quickly, if we stay doing these kind of activities we are going to finish with the drinkable water in the world, and also with a lot of animals that live in rivers, streams, etc.
Sources that supply drinking water in the metropolitan area of Monterrey
Surface water: The San Juan River with a surface area of 20,212 km2, accounts for 31.5% of the entire surface area of the State of Nuevo León and is the largest and most important river in supplying water to Monterrey.
Storage Reservoirs: El Cuchillo dam (1,123,000,000 m3 active capacity) was constructed 75 km upstream of the Gómez dam and began operations in 1993 primarily to supply water to Monterrey. The Marte R. Gómez (MRG) dam, constructed in 1936 just upstream of the San Juan's confluence with the Río Bravo, serves as the Bajo Río San Juan (BRSJ) irrigation district's principal reservoir with 829,900,000 m3 active storage capacity. The José López Portillo ‘Cerro Prieto’, reservoir (ordinary storage capacity 393 mm3) was built in the early 1980s in the adjacent Rio San Fernando watershed to supply the domestic and industrial water demands of Monterrey Metro Area (MAM), and was the first case of inter-basin transfer of freshwater to cope with shortages in Mexico’s northeast.
