Reading the gauges…

Follow San Lorenzo 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.

Follow this water

Signed in: one step. Otherwise we email a confirmation link first. Every alert has one-click links to stop it.

Where to fish

About this

Where the map point comes from

Position: a point on the mapped channel of “San Lorenzo 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: Steelhead / salmon 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 salmon & steelhead.

The water on the map

About this

Measured from the NHDPlus High Resolution (flowlines and waterbodies) (U.S. Geological Survey, read 2026-11-04) for this water’s own mapped feature. Rounded figures; they describe the channel, not today’s conditions.

Length
29.4 mi (28.4 in CA)
Drains

Watershed

Public land along it

About this

Areas the Protected Areas Database of the United States (PAD-US), public access (U.S. Geological Survey, Gap Analysis Project, read 2026-11-05) lists as owned or held in easement and open to the public, crossed by the mapped channel. Boundaries are mapped, not surveyed. Nothing on this page grants or implies access: check the agency map, posted signs and landowner permission before you fish.

Fish these abroad

About this

Matched on the fish the agencies list for both waters first, then the same water type, an official designation or flagship listing on both, and a similar mapped size where USGS hydrography covers both.

At most two waters per country. A shared fish is a listing, not a promise: presence varies by reach and season.
