The Ulan Moron begins as melt-off from the Geladandong glaciers and runs to a confluence with the Dangqu or Dam Chu River, where they form the Tongtian River, which subsequently becomes the Yangtze River. Although the Dangqu has been found to be the longest source of the Yangtze under the usual modern criteria, the Ulan Moron has been traditionally regarded as the main river and source. It belongs to the East China Sea watershed basin.

Notes
- In Chinese, the character 河 originally described the Yellow River and 江 the Yangtze. In modern practice, a jiang is usually a longer river, while he varies from shorter rivers (as the Tuotuo) to creeks (such as Suzhou Creek in Shanghai).
- But note Mei Zuyan who claims the Chinese name merely transliterates a former Tibetan name.[2] Bolstering his point is the alternate Chinese spelling of the river's name as the 托托. In fact, if the name was originally a transliteration, it probably derives from a variant of the Mongolian Togtoh.[3]
