红水河为西江干流的上游段,其起点由贵州南、北盘江汇合口——双江口算起,到广西象州石龙三江口,全长659km。水量充沛,年平均降雨量1481.7mm,最小流量222m~3/s,年平均流量2266m~3/s,年平均迳流量696×10~8m~3,为发电和航运提供了有利的自然条件。根据水电规划,从南盘江天生桥至大藤峡,将建设十个水电站,总装机容量为1034×10~4kW,指标十分优越,是水电的“富矿”,为十大水电基地之一。南、北盘江的下游段和红河水历来就是通航河流,在未建公路以前,是云南、贵州、广西三省(区)边陲地区的唯一交通要道。百层、岩架、蔗香、天峨等许多圩镇当年都是较繁荣的港埠,下航的主要物为山货土产、中药材等,上航的主要货物有食盐、日用百货等。水运对当地少数民族的经济、文化交流起过重要的作用。根据1960年的不完全统计,在南、北盘江及红水河上游段共有运输船舶490艘,总载重量1592t,
Hongshui River is the upper reaches of the Xijiang River. The starting point is from the confluence of South and North Panjiang in Guizhou and Shuangjiangkou to the Shilong Sanjiangkou in Xiangzhou, Guangxi. The total length is 659km. The annual average rainfall is 1481.7mm, the minimum flow is 222m ~ 3 / s, the annual average flow is 2266m ~ 3 / s, and the average annual flow is 696 × 10 ~ 8m ~ 3, which provides favorable natural conditions for power generation and shipping. According to the hydropower plan, from Nanspanjiang Tianshengqiao to Odengxia Gorge, ten hydropower stations will be built with a total installed capacity of 1034 × 10 ~ 4kW. The indicator is extremely advantageous. It is a “rich ore” of hydropower and one of the ten major hydropower bases. The downstream sections of the South and North Panjiang River and the Honghe River water have always been navigation rivers. Before the roads were built, they were the only thoroughfares in the border areas of Yunnan, Guizhou and Guangxi provinces. Hundreds, rock shelves, cane incense, Tian E and many other Wei Zhen was more prosperous port of the year, the main cargo for the sampan indigenous products, Chinese herbal medicines, the main cargo of Shanghai Airlines salt, daily necessities and so on. Water transport has played an important role in the economic and cultural exchange with local ethnic minorities. According to the incomplete statistics in 1960, there were 490 shipping vessels in the upper reaches of the South, North Panjiang and Hongshui rivers with a total carrying capacity of 1592 tons,
