Visibility Breakdown
Visibility by position
Solid = diver report · outlined = our reading
Break Zone: The range of water where the waves break and sediment is stirred up.
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.

Treasure Island Beach is a sand beach in Laguna Beach, Orange County, set below the bluff in front of the Montage Laguna Beach resort. A long paved ramp leads down to the sand from the public walkway along the top of the bluff. Treasure Island Park covers the blufftop with lawns, benches, and picnic tables, and restrooms and showers serve the beach along with a lifeguard stand. The name comes from the Treasure Island mobile home park that stood on this bluff before the resort. West of the beach, Goff Island is a large rock tied to the mainland by a spit of sand, and Goff Cove beside it is reached by a stairway from the north end of the walkway. Rocky points and tidepools line both ends of the beach at low tide.
Surf breaks straight onto the open sand at the center of the beach, which places Treasure Island Beach in the surf zone biome. Rock runs out from both points and from Goff Island into the shallows, and the rocky reef biome there is cut by cracks, overhangs, and small caves. Between the reefs, bare sand bottom makes up the sandy flats biome, and depths across the site run from about 10 to 30 feet. Rocky points and tidepools at both ends of the beach, exposed at low tide, add a Tidepools biome at the edges of the sand.
Swimming and sunbathing carry most of the use on the sand, and the tidepools at both ends draw visitors at low tide. Snorkelers and scuba divers work the reefs off Goff Island and along the points. A common route enters at the Goff Cove stairs, heads southeast to the reef off the beach, and exits up the ramp. The beach faces open swell rather than sitting in a sheltered cove, so surge can run strong off the points and in the shallows when the waves pick up.
Paid public parking sits in the city's Treasure Island garage at Wesley Drive and South Coast Highway, near the top of the ramp. Under California Code of Regulations Title 14, all take of living, geological, and cultural marine resources is prohibited in the Laguna Beach State Marine Reserve, which covers Treasure Island Beach, and in the Laguna Beach State Marine Conservation Area (No-Take), which begins just to the south.
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.

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.

Sandy Flats
The sandy flats biome is open sand bottom past the breaking waves, from the sand slope off a beach to the sand channels and plains between reefs. Worms, clams, and other small animals live buried in the sand, and halibut and rays bury themselves in it to hide and hunt.

Tidepools
The tidepool biome is rocky shore that the ocean covers at high tide and uncovers at low tide. Pools left behind in the rock hold anemones, sea stars, urchins, snails, crabs, and small fish that can handle hours of sun and air between tides.
