Recent rainfall can influence river flow, but the timing and magnitude depend on watershed size, soil conditions, upstream reservoirs, and dam releases.

Fishing Overview

Bounded South Branch Raritan trout reach centered on the Ken Lockwood Gorge / High Bridge corridor. This is not an undifferentiated whole-river South Branch Raritan destination and not the North Branch Raritan. USGS station 01396500 near High Bridge is an acceptable proxy for this bounded fishing reach: it monitors the High Bridge gauge subreach and does not capture every gorge microhabitat nuance. Live water-temperature IV at this station is stale and not usable as current measured temperature.
