Henggang Reservoir was built in December 1959. It is a medium-sized reservoir dominated by water storage. Its fish culture area is 2.2 square kilometers and 3,300 acres. In the long term, due to the attention of the reservoir leaders, the stocking, fishing and management of reservoirs and fisheries have been conscientiously grasped so that the yield of the reservoir fish can be continuously increased. In 1965, the fish farming of reservoirs began. The average annual yield per mu was 19.2 kg in 1965-69, 27.8 kg in 1970-73 and 45.1 kg in 1974-77. The output of fish increased year by year over the past decade, reaching a high and stable yield. The reservoir is located in the northwestern part of Da Ling Shan, Dongguan City, Guangdong Province, near the commune commune, 113 ° 34 ’east longitude, latitude 22 ° 55’ between the reservoir rainfall area of 36.7 square kilometers, normal high water level, the storage capacity of 2,125 million cubic meter.
