River Flow


Humboldt County area Real-Time River Flows !


These flows are provided as a service to help cannabis farmers plan for the most sustainable farming.

All north coast rivers are subject to low flow fishing closures, generally late summer to early winter.

Call the CDFW Low Flow Closure Hotline at (707) 822-3164 to determine if the river is open for fishing!

Water diversions for farming should be avoided during low flow!
