History
Water exports
In the early 1960s, the increasing demand of fresh water in Hong Kong was increasing due to a growing population. The government saw that the most efficient way to fulfill the unmet water needs was through the fresh water sources in neighboring Guangdong. On November 15th, 1960, The government reached an agreement with Guangdong authorities to take 23 million cubic meters of water a year from the Shenzhen Reservoir, which itself was connected to the Dong River.
Later, additional pumping stations and dam works were built to further extend the supply. The new annual volume of water increased to 620 million cubic meters. More extensions in 1990 upgraded existing stations, leading to a new volume of 1.7 billion cubic meters of water, of which 1.1 billion went to Hong Kong, 493 million to Shenzhen and 150 million for irrigation along the river.
Since 1960, 12 supply agreements have been signed, of which all were based on consumption projections in Hong Kong.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Dong River (China)”, the useful work is to connect “river in Guangdong, China” to the records capable of establishing context and consequence.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Jul 2, 2026. The linked authority identifier is Q285137. VIAF identifies the subject as 315146086. Authority coordinates are 23.037, 113.518. 1 of 3 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank. The first chronological checks are 1960 and 1990.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
