Visibility Breakdown
Visibility by position
Solid = diver report · outlined = today's forecast
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.

About Bird Rock
Bird Rock is the white-streaked pinnacle that breaks the surface about half a mile off the mainland side of Isthmus Cove at Two Harbors. Locals also call it White Rock, after the layer of guano that generations of cormorants and gulls have left on the top. Below the waterline the structure is entirely rock, with a shallow reef wrapping the perimeter from about 15 feet down. The west face is a steep vertical dropoff that runs from 30 to 60 feet, with an arch cut through it at the same depth band. The sheltered north and east faces carry giant kelp anchored at about 50 feet of depth and grown up through the water column to the surface. A second dropoff at around 80 feet leads down to sand barrens. Sea lions haul out on the exposed rock above the water.
