South Branch Raritan River is a freestone river in New Jersey.
Pick one of its USGS gauges and hear from us when the flow moves into or out of its usual range for the date, or crosses a flow you set. We check the public USGS reading every 2 hours and email only when it crosses, at most once every 6 hours. Flow alone is not a fishing forecast or a safety call.
Signed in: one step. Otherwise we email a confirmation link first. Every alert has one-click links to stop it.
Start from the agency's public access map. Nothing on this page grants or implies access: check the agency map, posted signs and landowner permission before you fish.

Normal for this date. 114 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 110 years of record (1904–2026): 10th 58, 25th 86, median 124, 75th 203, 90th 371 ft³/s.
Daily means on record for Nov 5: lowest 30 ft³/s, highest 887 ft³/s.

Steady over 24 hours (gauge height +0.01 ft). Rising or falling means a change of more than 10% in discharge (or 0.2 ft of gauge height) over 24 hours; our rule of thumb, not a USGS class.
NWS observed 2.15 ft stage, 147 ft³/s at Nov 5, 5:15 PM EST (NWS gauge SBNN4; its stage datum can differ from the USGS gauge height).
NWS has not set flood categories for this gauge.
Forecasts are not available. Only observed stages are available for this point.

No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. New Jersey Fish and Wildlife publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a New Jersey rule, with New Jersey Fish and Wildlife's own figure added: 68°F and 72°F.
This gauge is on our page for South Branch Raritan River, but no agency page we read lists its species.
Turn Around Don't Drown. “A mere 6 inches of fast-moving flood water can knock over an adult.” No flow number makes a crossing safe; if in doubt, stay out.
Turn Around Don't Drown (National Weather Service)Guidance from the readings above and the published thresholds named with each line; not a fishing forecast, a safety guarantee or a statement about access. Local rules and closures come first.
Checked Nov 5, 6:22 PM EST; readings refresh at most every 15 minutes and statistics daily. Provisional USGS data can be revised. Conditions change: re-check before you go. This is general guidance, not a fishing forecast, a safety guarantee or a statement about access.
