About this water

A managed fishery on township road Y208 in Liulimiao, in the northern Huairou hills, on a tributary of the Bai river system rather than the closed reserve rivers to the south. It opened in late 2024 and permits both fly fishing and lure, with lure restricted to single-hook hard baits. A flood reshaped the channel and left the water notably clear; the trout now sit at around a metre, shallow enough to fish by sight. It is the natural second stop after Trout Season 鳟鱼季, an hour or so away on the far side of the same range. / 琉璃溪谷管理钓场位于怀柔北部琉璃庙镇二零八乡道,属白河水系支流,与南面禁钓的保护区河流不同。2024年底开放,允许飞蝇钓法与路亚,路亚限用单钩硬饵。洪水过后河道改变,水质格外清澈,鳟鱼多停留在一米左右水层,可视钓作业。与鳟鱼季同属一山两侧,是顺路的第二站。

Under the surface

A managed valley stream in the Liulimiao hills, rearranged by a flood that scoured the channel and left the water clearer than it was before. The trout hold shallow here, a metre or so down, in water you can read from the bank. / 琉璃庙山谷中的一条管理溪流。一场洪水改变了河道形态,却让水质比从前更清。鳟鱼多在一米左右的浅层,站在岸上便能看清水下情形。

What would change the calculation
Warmer water — toward the 10–18 °C ideal band — would lift the temperature score.
