• Feature and flow postureSpring/high-water Class II–III reach; Harper Falls is a mandatory carry; no numeric threshold accepted

  American Whitewater supplies route-specific feature and portage guidance. Use Chase Mills only as downstream same-river trend context; the historical North Branch mouth station has no live discharge series.

• Proxy flow contextUSGS 04265432 Grass River at Chase Mills

  This is downstream same-river telemetry, not a local North Branch threshold; compare broad trend with local rain, visual level, wood, and cold-water conditions.

• Same-river proxy gaugeUSGS 04265432, Grass River at Chase Mills, NY

  USGS 04265432 at Chase Mills is a downstream same-river proxy for this North Branch reach. The historical USGS North Branch mouth station 0426475505 is on the route corridor but currently has no live discharge series; use the Chase Mills trend only with local rain, water level, wood, temperature, and feature checks. No numeric threshold is asserted.

• Safety and river conditionsCheck live gauge, recent rainfall, trend, debris, bridges, and access conditions before launch

  American Whitewater / NYSDEC Grass River and Church Pond access plans and its linked safety material warn that conditions change rapidly and require local inspection.
