La Yesca Dam

La Yesca Dam is an embankment dam on the Santiago River 90 km (56 mi) northwest of Guadalajara on the border of Mexico's Nayarit and Jalisco states. Construction on the dam began in 2007 after Empresas ICA was awarded the main construction contract. The dam was inaugurated by President Felipe Calderón on 6 November 2012.[2] The dam supports a 750 MW hydroelectric power station and is part of the Hydroelectric System Santiago.[3] Its construction will improve the regulation of water flow and subsequently power generation downstream at the El Cajón and Aguamilpa Dams.[4]

Design

The La Yesca Dam is a 220 m (722 ft) tall and 628 m (2,060 ft) long concrete-face rock-fill embankment type with 11,900,000 m3 (15,564,612 cu yd) of fill. The dam's crest elevation is 579 m (1,900 ft) above sea level and it sits at the head of a 51,590 km2 (19,919 sq mi) catchment area. On the dam's left bank is a spillway controlled by six radial gates. The maximum discharge of the spillway is 15,915 m3/s (562,033 cu ft/s). The dam's reservoir has a capacity of 2,500,000,000 m3 (2,026,783 acre⋅ft) of which 1,392,000,000 m3 (1,128,513 acre⋅ft) can be used for generating electricity. The reservoir has a surface area of 33.4 km2 (13 sq mi) and a normal elevation of 575 m (1,886 ft). The power station contains two 375 MW Francis turbine generators producing an estimated annual generation of 1,210 GWh.[1]

gollark: Are you still going for the ridiculous "I'll buy all my parts over 3 years" thing?

gollark: I'm trying to get the CBOR library skynet uses to run, but due to the stupidity of all JS tooling the compiler just outputs a ridiculous error.
gollark: Parcel is a nice zero-configuration bundler, except the zero-configuration approach and the fragility of the JS ecosystem means it just broke for no reason.
gollark: Ugh, I'll just use webpack and make myself suffer probably more.
