Lao Wo River
Lao Wo River is the largest first-level tributary on the left bank of the Nujiang River within Lushui City. Located in the Nujiang Gorge area of western Yunnan Province, it is situated in the northeastern part of Lao Wo Town. The river originates from Jiazong Mountain in Po Jiao Village, Caogang Town, Yunlong County, Dali Prefecture, and is formed by numerous tributaries. Lao Wo River has about 34 major and minor tributaries. The upper reaches are known as Fen Shui Ling River, while the lower reaches are referred to as Lao Wo River. Flowing from east to west, it passes through eight village committees, including Ronghua, Lao Wo, Zhongyuan, Yinpo in Lao Wo Town, and Duanjiazhai, Baishuihe, Xinzai, and Liuku in Liuku Street, before merging into the Nujiang River. The river’s source elevation is 3,168 meters, with a basin area of 579 square kilometers and a river length of 44.6 kilometers. In Lushui City, Lao Wo River is 36.79 kilometers long, with a basin area of 456.7 square kilometers. The elevation at the entry point is 2,187 meters, and the elevation at the river mouth is about 800 meters, with a total drop of 1,378 meters and an average slope of 37.46‰. The designated scenic segment for this beautiful river and lake application extends from the river’s source to Yinpo Village. The banks of this section of Lao Wo River are well-vegetated, with evergreen mountains and a beautiful environment. Since the implementation of the River Chief System, the Lao Wo River has established a three-tier river chief system at the city, town (street), and village levels. Each level of river chief fulfills their responsibilities, overseeing the river’s management and restoration, including riverbank greening projects. New flood control embankments of 4.27 kilometers have been built to effectively protect the safety of the local people and farmland.
Lion and Elephant Bridge on Lao Wo River
Located about 30 kilometers east of Liuku, the Lion and Elephant Bridge is situated near the entrance of the village road in Chongren Village, Lao Wo Town. The bridge features pavilions on both the east and west sides, decorated with intricate carvings of dragons, lions, elephants, and sacred deer. Built by skilled craftsmen from Jianchuan, Eryuan, and Dali, it is also known as “Chongren Flower Bridge” or “Lao Wo Flower Bridge.”
Historically, Lao Wo Town was governed by the Duan Clan of Yunlong. During the Ming Dynasty’s Wanli period, the Duan Clan began constructing an ancient road from the Lancang River’s Feilong Bridge to Pienma Old Road, which crossed various mountains and rivers, including Lao Wo, and extended to the border with Myanmar. This trade route facilitated the exchange of goods such as tea, dairy products, and salt.
The Lion and Elephant Bridge, completed in the second year of the Jiaqing era (1797), was part of the Southern Silk Road’s Bounan (now Yongping) ancient road and an important transportation bridge for the Liuku area. The bridge’s piers are made of stone, with a brick and wood structure and a tile roof. It has been rebuilt five times, with the most recent reconstruction in 1987, where it was reinforced with reinforced concrete and decorated with carvings while maintaining its original architectural style.
The Nujiang River area is known for its diverse bridges, including suspension bridges, stone arch bridges, and others, earning it the nickname “Bridge Museum.” Despite its historical significance, the Lion and Elephant Bridge remains a testament to the perseverance and spirit of the people who built it, continuing to inspire future generations.

The No. 4 Hydropower Station, situated in Baishuihe Village within Lushui County, is the tenth stage of the Lao Wo River’s eleven-stage hydropower development plan. The station plays a significant role in harnessing the river’s water resources and promoting economic development in the border region. It features a single-purpose power generation design and is classified as a Class I small hydropower station. The facility includes an intake hub, diversion system, and plant hub, with an installed capacity of 25 MW (2×12.5 MW) and an average annual power generation of 123.5 million kWh.
Top Main Rivers in Yunnan Province
Chinese Name:南腊河
English Name: Nanla River in Mengla County, XishuangBanna
The Naluo River (meaning “river of tea water” in Dai language), located in Mengla County, Yunnan Province, People’s Republic of China, is the final tributary of the Lancang River (Mekong River) before it flows into its main stem within Chinese territory. Its main source, the Nandao River, originates from the hinterland of Daqingshuzhai, Jinchang River Village, Mengban Town, eastern Mengla County. It flows northwest to southwest through Mengban Town, Wanguan Tree Scenic Area, and Mengla County town, then turns west near Manmai in the southwest of the county to join the Nanmuwo River, flowing northwest to north at Manpeng Village, Mengpeng Town, and westward at Mangang Village, Guanlei Town, finally converging with the Lancang River at the junction of China, Myanmar, and Laos, known as the tri-border area.
The river has a total length of 186.8 kilometers, with a drop of 850 meters, an average channel slope of 1.8‰, and a basin area of 4570 square kilometers (3911 square kilometers within China). The climate in the Naluo River basin is hot with high humidity, averaging an annual temperature of 21°C and annual precipitation of 1550 millimeters. The basin is rich in forest resources, with a forest coverage rate of 73.2%. The Mengla and Shangyong areas of the Xishuangbanna National Nature Reserve are located within the basin. The area is inhabited mainly by ethnic minorities such as Dai, Hani, Yao, and Yi. Rubber planting is the dominant economic activity, making it a major region for natural rubber production in Yunnan.
The Nanla River, part of the Lancang River system, stretches approximately 186 kilometers and is the final primary tributary of the Lancang River before it exits China. The river meanders through a rugged landscape with numerous tributaries, including the Nansha River and Nangang River. Due to its hot and humid climate with abundant rainfall, dense forests cover the entire Nanla River basin, with some of its tributaries yet to be fully explored.
The Nanla River, renowned for its beautiful legends, flows through the Wantianshu Tropical Rainforest Theme Park in Xishuangbanna. The riverside rainforest scenery is exquisite, filled with the clear calls of birds. The river hosts over a hundred species of fish, including the rare and precious “Peach Blossom Jellyfish” surviving in its waters.
Originating between Xiangguntang Mountain in Mengla County and Daqingshuliangzi, the river basin spans the southeastern part of Mengla County. It is the largest river within Mengla County and a primary tributary of the Lancang River system. The main channel passes through administrative towns such as Mengban, Yaoqu, Mengla, Shangyong, Mengpeng, and Guanlei. Flowing from northeast to south, the river turns west at Mengpeng Town, joining the Lancang River at the border tri-junction of China, Laos, and Myanmar at Guanlei. With a total length of 186 kilometers, the river is 30 meters wide with a drainage area of 4563 square kilometers. The natural drop in elevation along its course is 1065 meters, averaging a slope of 4.03%. The average annual water flow is 22.27 billion cubic meters, making it a vital irrigation source for Mengla County.
Geographically, the Nanla River basin lies east of the Lancang River Fault, characterized by varied terrain ranging from the highest point at Leigongyan with an elevation of 2008 meters in the north, to the confluence with the Lancang River at an elevation of 477 meters in the west. This extreme elevation difference spans 1531 meters.
The Nanla River is a magical place with elegant bamboo houses, beautiful phyllostachys, Dai girls in colorful tube skirts, temples, pagodas, elephants, peacocks, Wantianshu trees, dancing grass, Zhangha songs, and elephant-foot dances, all set against a backdrop of rainforest, encompassing all the wonders of Xishuangbanna!
