High waves and heavy surf that have battered the Sonoma Coast for days and sealed the Russian River mouth with a great mound of sand have raised the water high enough to threaten flooding in the town of Jenner over the next few days.
Water already surrounded the Jenner Visitor Center at the river’s edge by Thursday afternoon, rising over the back deck and flooding into the parking lot adjacent to the post office and Highway 1. Farther inland, the river’s surface swelled to a height of 10 feet at the Highway 1 bridge.
But because of continued wave action on the beach, it has not been safe for Sonoma Water, the county water agency, to send out a heavy equipment operator to breach the beach dam by digging a channel through from the river estuary to the ocean. And though there has been some recent rain, the river flow remains low enough that it’s not exerting sufficient pressure to break through the sand on its own.
That combination of factors has allowed the mouth to close a “crazy” number of times this winter, said Suki Waters, who grew up in the area and owns Water Treks EcoTours in town, running boat rentals and guided kayak tours in the estuary.
