Summarize this article for a 10 year old
The Xinfengjiang Dam (Chinese: 新丰江水电站; Jyutping: san1 fung1 gong1 seoi2 din6 zaam6, also known as the Xinfeng Dam) is a gravity dam on the Xinfeng River, 8 km (5 mi) upstream of its confluence with the Dong River, and just west of Heyuan City in Guangdong Province, China. The dam's power station has a 292.5 MW installed capacity and its reservoir supplies water for farming along with drinking water to Guangzhou, Shenzhen and Hong Kong. Construction on the dam began in 1958, the first generator was operational in 1960 and the dam complete in 1962. The dam's reservoir-filling is attributed to several earthquakes within the project area including a 6.1-magnitude (Mw) on March 19, 1962.
