About this water

The Fenshui is the largest of the Qiantang tributaries in this pack and the one the Hangzhou blogger who fishes Huyuan and Gexi also names. Tonglu's own fisheries regulations set a named closed reach on it — 分水江老大桥 to 横村一桥 — and exempt recreational angling from the closure, which makes its legal position unusually explicit for a river this size. / 分水江是本册所收钱塘江支流中最大的一条，也是那位常钓壶源溪与葛溪的杭州博主点名的水域。桐庐县天然水域渔业资源保护实施办法明确划出分水江老大桥至横村一桥的禁渔河段，并将休闲垂钓排除在外，法律位置对这样体量的河流而言相当清楚。

Under the surface

The big tributary of the Fuchun, running down out of the Lin'an hills through Tonglu. Wider and slower than the streams above it, with the joint patrols of two counties working its length. / 富春江的主要支流，自临安山区下行，穿桐庐而过。较上游诸溪更宽更缓，两县渔政沿江联合执法。

Wading: Larger river, joint enforcement patrols, flashy summer spates

Conservation note

⭐ Nothing here is protected. 马口 (*Opsariichthys*) is scored. On a river this size 翘嘴 is the popular lure quarry and has no engine profile, so it stays prose-only. / ⭐ 此处鱼种均非保护物种。马口已纳入计分。此等体量的河流以翘嘴为路亚热门，但无引擎模型，仅作文字说明。

What would change the calculation
Warmer water — toward the 20–26 °C ideal band — would lift the temperature score.
