Tuolumne River is a tailwater in California.
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.

Seasons, limits, special regulations and closures for each reach are on the agency pages below. Read them before you go.
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.
On the Designated Wild Trout Waters (Fish and Game Commission) list (California Department of Fish and Wildlife / California Fish and Game Commission, read 2026-10-16). All waters with this designation

Not a statement of access, fish presence or conditions.
A water page organises discovery. It does not assert public access, legal access, current fish presence, guide availability or fishing conditions.
Flows, gauge statistics and flood stages come from USGS and the National Weather Service when the page is shown. Regulations, stocking, species and season statements link to the agency that publishes them; this page copies only the species names and the quoted sentences. Guide and shop listings come from the Legendary directories. Position: the USGS gauge TUOLUMNE R BL LAGRANGE DAM NR LAGRANGE CA. Water type is our own classification.
