Post Break: The range past where any waves are forming, where the water starts to have a significant increase in visibility. There might be some sediment here, but swell energy is diffused and the water is calmer.

Open Water: This zone is far out enough from the shore that the water is at its clearest. It’s deep enough that sediment is not disturbed by the wave energy at the surface. Haze can sit near the surface, so the water is usually clearer the deeper you go.

Field notes

About Russian Gulch Beach

Russian Gulch Beach sits at the mouth of Russian Gulch Creek, where the drainage cuts a deep W-shaped cove just north of the Highway 1 bridge over the gulch. Pebble and cobble line the beach, and rocky headlands wrap both sides. Inside the cove, the water runs roughly 5 to 15 feet deep, sloping out to 30 to 40 feet past the mouth. The site is the northernmost of the Sonoma Coast State Park dive coves south of Jenner.

The beach is a surf zone biome, with cobble underfoot and shore break on any swell. Boulder and cobble reef around the cove mouth make up a rocky reef biome, patchy and open where the gulch flushes out to sea. Seasonal bull kelp grows on that outer reef through the warmer months and dies back each winter, and that annual, single-stipe growth is the kelp forest biome here. The canopy is thinner than it was before the 2014 to 2019 collapse that swept the Sonoma and Mendocino coasts.

A rip current out of the cove is documented, so swimming is not recommended. Northwest swell hits the entrance directly, and the site is not workable on rough days. Freediving and scuba are the working uses, with rockfish and lingcod the legal take on the reef. The coast was a headline recreational abalone destination through the 2010s, but that fishery has been closed statewide since 2018. Beachcombing and tidepooling draw the rest of the traffic.

Parking is a small paved pullout on the ocean side of Highway 1, just north of the bridge, with no fee and no facilities. The pullout fills on summer weekends, and shoulder overflow is legal only where signed.

Fishing and spearfishing are legal here under standard California regulations. The Russian River SMCA lies roughly 0.6 nautical miles to the south, where take of anything other than recreational Dungeness crab and surf smelt is prohibited.

Biome

Surf Zone

The surf zone biome consists of sandy beaches and breaking waves. The action of surf disturbing the sand and kicking it up exposes marine invertebrates, buried in their shallow dens. This natural exposure of invertebrates attracts all kinds of fish, looking for an easy meal. Learn more about this biome and the species found in it by clicking the link below.

Sub-biome

Rocky Reef

The rocky reef biome is bare rock, boulder, and cobble structure without a kelp canopy above it. The hard relief and its crevices shelter invertebrates and reef fish, and the structure concentrates life that the surrounding sand cannot hold.

Sub-biome

Kelp Forest

The kelp forest biome is giant kelp anchored to rocky bottom and growing up through the water column. The canopy and stipes form a three-dimensional habitat that shelters fish, invertebrates, and the predators that hunt them.
