Alerts
Choose the creeks you care about and the level that matters to you, and get an email or a text when a gauge crosses it. 32 gauges publish numbered thresholds, and every one of them can be watched.
Both messages below are composed from a real gauge and a real threshold description, so you can see the shape of a message before you subscribe.

Valley Water, threshold 2 description for Stevens Creek above CA-85 near Central Ave
This is Valley Water's own description of what floods at this level, quoted exactly. It is not a forecast, and it is not an evacuation order. For an emergency, call 911.
Every email carries the unsubscribe link and the link to change which creeks you follow.
Nothing you enter above is sent or stored. The preferences form is not yet connected to Valley Water's messaging account, so it checks your entries, shows them back to you, and stops there.
An alert goes out because Valley Water sends it. Nothing on this page decides that. If a message does not reach you, that is caught rather than silently dropped, because a bounced address in November is a person with no warning in February.
Behind the message
Releases, gates and outlet works are run by Valley Water staff and their contractors. An alert describes what that operation and the weather did to a creek; it is a report of the district's work, not a substitute for it.
An alert from this system reports a gauge reading Valley Water chose to send. It is not a prediction, it is not an instruction, and it does not know where you are standing. Emergency instructions come from your city, your county, and the fire department. For an emergency, call 911.
