Check any river's flow

Follow Middle Fork San Joaquin River for flow alerts

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.

Where the map point comes from

Position: a point on the mapped channel of “Middle Fork San Joaquin River”, halfway along its length in California, from the USGS high-resolution hydrography (NHDPlus HR), read 4 Nov 2026. It marks the water, not a particular access or reach.

The map shows USGS gauges (tap one for its flow reading), and shops and guides within 40 miles that publish a street address on their own website. Everyone else is in the lists below.

Regulations

About this

Seasons, limits, special regulations and closures for each reach are on the agency pages below. Read them before you go.

Official designation: Wild Trout Water

Each comes from the agency's own published list; where the list names a reach it is quoted. A designation applies to the listed reach, not necessarily the whole water. Listed in the finder under trout.
