The Mengtun runs off the high snow of the Qionglai range through a Qiang valley of stone watchtowers and pine forest west of Chengdu, before joining the Zagunao and, below that, the Min. It is the one Chinese river with independent first-hand fly-fishing accounts behind it and a working outfitter on it — cold pocket water fished with light rods and weighted nymphs at around two thousand metres. It is also water inside the Yangtze ten-year fishing ban, where angling is governed by closed zones, a closed season of at least four months, and a strict limit of one rod and two hook points. Read this as a place to understand before you travel, not a fishery you can plan a day on — and note that unlike the two Beijing fisheries in this pack, nothing here is simply open and ticketed. / 孟屯河源出邛崃山脉的高山积雪，穿过成都以西一处遍布羌族碉楼与松林的河谷，先汇入杂谷脑河，再入岷江。它是国内唯一有独立第一手飞钓记述、且有在营渔具向导的河流——海拔约两千米的冷水急流，用轻竿与加重若虫作钓。此地同时位于长江十年禁渔范围内，受禁钓区、每年不少于四个月的禁钓期，以及一竿一线、钩尖不超过两个的严格限制约束。请将本页视为出行前的了解材料，而非可据以安排钓程的钓场——与本册中两处北京钓场不同，此处并非买票即可入场。
A snowmelt river in the Qiang and Tibetan valleys west of Chengdu, running off peaks beyond five thousand metres through pine and rhododendron to the Zagunao below. The water is cold and fast over grey stone, the pools short, the season narrow. Villages of stone towers stand along it, and the valley is walking country long before it is fishing country. / 成都以西羌藏河谷中的一条雪融河流，源出五千米以上的雪峰，穿过松林与杜鹃，注入下游的杂谷脑河。水冷流急，灰岩铺底，潭浅季短。沿岸立着石砌碉楼——这里首先是徒步的山谷，其次才是钓鱼的河。
