Permits & access
Permit required — see local rules.
  • A managed fishery (管理钓场), so it sits outside the natural-water closed-season regime and trades through it
  • Fly fishing is explicitly permitted
  • Confirm the current ticket — ¥150/day and ¥188 including one fish and lunch have both been reported and may be different tickets or seasons
  • Phone 13910325662
  • ⚠️ The stream beside the fishery is the 雁栖河, one of the 16 Huairou rivers closed to angling YEAR-ROUND, and the whole 怀沙河/怀九河 reserve was closed to angling and water entry on 2026-08-07
  • The ticket buys you the managed water only — do not fish the open river on the other side of the road

Conservation note

Stocked rainbow and brown trout are the scoreable fish. Golden rainbow (金鳟) is a colour variant of rainbow trout and is described in prose only, never scored separately; 红点鲑 is reported but ambiguous between brook char and white-spotted char, so it too stays prose-only. / 放养虹鳟与褐鳟为主要对象鱼。金鳟为虹鳟的体色变种,仅在文字中说明;红点鲑的具体种类存疑,同样不单独计分。

What would change the calculation
Warmer water — toward the 10–16 °C ideal band — would lift the temperature score.
The dawn and dusk windows score higher than the midday lull.
