Record-Breaking Rainfall Hits Mattole River Region During Recent Storm

An environmental nonprofit near the Mattole River headwaters has documented record-breaking rainfall during last week’s storm, with totals surpassing 25% of the region’s annual average in just a few days. Lauren Schmitt reports…
Summary:
The Mattole River surged over 16 feet during last week’s bomb cyclone-turned-atmospheric river, with rainfall totals breaking records for November, according to Sanctuary Forest. The storm delivered over 25 inches of rain to the headwaters, surpassing a quarter of last year’s total rainfall and marking the wettest November in over a decade. This rain ended forbearance restrictions on the watershed and opened the river’s mouth for migrating salmon.
Sanctuary Forest’s efforts to manage and enhance river health include streamflow augmentation through their “String of Pearls” pond project and the use of analog beaver dams. While the rainfall brings much-needed relief, the nonprofit emphasizes the importance of sustained spring rains for long-term ecosystem balance. They also highlighted ongoing restoration work and invited the community to their upcoming fundraiser, Luna, a Beacon of Hope, to support future conservation efforts.
