Hongchao River originates from He Jiong of Lingshan, flows into several secondary tributaries, and flows southward into the junction of Shiwan and Wu Jia in the north of the county. Then southbound for about 15 km to the west spider slope of Qingshui village in Shiwan, where it flows into the male goose beach of Nanliujiang River, then flows southwest for about 8 km, crosses the southeast of Shangyangwei, and flows into the main stream of Nanliujiang River in the south of Tianliao village in Shagang by 750 artificial river. Before 1967, it flows through the northern and western parts of Tianliao Village, meanders about 15km to the southwest, and joins the Nanliu River in the northern part of Shagang.
The total length of the main stream of Hong Chao is 106 km, with a drainage area of 458 square kilometers. The county river is 23.3 kilometers long, with a drainage area of 90.5 square kilometers, which can develop 3600 kilowatts of hydraulic resources. The annual average flow is 1 1.5 cubic meters per second. There are large reservoirs at the junction of Hepu, Lingshan and Qinzhou in the middle reaches, and rivers are often impounded during non-flood season. The water surface of the river in the north of Qingshui Village is 10 meter wide or even tens of meters deep in the normal period. After the confluence and diversion of Nanliu River, the river course has been preliminarily regulated. The shore distance is about 250 meters, the water surface is tens of meters in normal season, and the water depth is less than 1 meter. During the flood season, 23% of the main stream of Nanliujiang River is discharged. The designed safe flood discharge for river regulation is 1800 cubic meters per second. Nanning-Beihai highway trunk line crosses the river east of Shangyangwei, and there is a Shangyang highway bridge. 1960 years ago, a ship of 10-20 tons could reach Lingshan Shengping by going up the river. After the completion of Hong Chao Reservoir, shipping has been suspended.
Baisha River (Shagang) originates from the northern part of Wujiawang Laoshan Village, flows southward to Baishajiang Village in Shagang, flows eastward into the old road of Hongchaojiang, and then flows southwest through the Beikong Gate along the old road into Nanliujiang. The drainage area is 52.3 square kilometers, the length of the main stream is 18.6 kilometers, and the annual average flow is 1.3 1 m3/sec. Shagang Pingshui River is 30-50m wide and 0.3m deep. The platform along the river suffered from serious soil erosion, and the beach was covered with sand. When it doesn't rain, the water surface only accounts for a small part of the river overflow. After the heavy rain, the river surged and plummeted, bringing a lot of sediment deposition. There is a barrage in the middle reaches; Water can be diverted to irrigate farmland in dry season.
Duck Ma Jiang originated in Shagongling Village, Zhang Qu Township, west to the east of Changle Town, and there are many streams in the northeast hilly area of Huihe County. It is divided into three tributaries near Sanjiangkou Village, Liannan Town, Changle Town, and flows into Nanliuhe in Liannan Town, Shikang Town and Songshuyuan Village respectively. The main stream is 22.4 kilometers long, the drainage area is 76.5 square kilometers, and the annual average flow is 1.93 cubic meters per second. The middle and lower reaches of the river are 20-30m wide and 0.4-0.9m deep. There is a dam in Shicheng, Changle Town in the middle reaches, which can irrigate more than 3,000 mu of fields.
Qingshui River originates from Xishan, Dongchong Village, Hongbei Town, Shikang Town. It joins several small rivers in the northwest of Qingshan Mountain, flows westward through the hills and plains in the east of the city, and joins the tributary of Nanliu River near Gao Qiao Toucun, the office of Qingjiang Village around the city. The length of the main stream is 13.2km, the basin area is 1 10.4km2, and the average annual flow is 2.77m3/s. The Qingshuijiang Reservoir has been built in the middle reaches, which usually intercepts most of the flow and stores water to irrigate the fields. The water surface at the place where it flows into Zhoujiang River is several meters wide and 0.2m deep.
Dagoujiang River is also a nominal river management, which originates from the east of Lingcun Village on the edge of CCBA in Ding Cun City, Wu Jialing, and flows south in the northwest hilly land, passing through the south of Wu Jia and the east of Xichang Town, and flows into the mouth of Nanliu River at the boathouse in the southeast of Xichang Town. This river that flows into the sea is called Dagang River. The main stream is 35 kilometers long, with a drainage area of 148 square kilometers and an average annual flow of 3.74 cubic meters per second. The east sluice has been built in the middle reaches, and the river section about 5 kilometers below the sluice to Gaogang Bridge has been manually straightened, with a width of 20-50 meters and a depth of about 0.5 meters. The sugar wastewater from Xichang Sugar Factory is discharged into the river under the sluice, which makes this section of the river often polluted and undrinkable during the sugar factory's harvest season. The nearshore reach of the port estuary is tortuous, with the width between dikes 100-300m and the low tide depth of about1m.. Mangroves are distributed in patches on the beach.
