The tide pulls 337 million cubic feet of water out through a narrow inlet, exposing more than 1,500 acres of mudflat where herons stalk and clam diggers bend. Twice a day, it refills. This rhythm -- measured, predictable, ancient -- has shaped everything that lives here and every human community that has tried to make a living from these waters. Five miles southwest of Tillamook on the northern Oregon coast, Netarts Bay is Oregon's seventh largest bay, tucked between the headlands of Cape Meares to the north and Cape Lookout to the south.

Whiskey Creek Shellfish Hatchery, one of the largest oyster larvae producers on the West Coast, sits on the bay's shore. In the late summer of 2007, the hatchery's larvae began dying en masse -- zero production for mont...

Netarts Bay: Reading the Water

Wed, 18 Mar 2026 00:00:00 GMT

Photo credit Meronim, CC BY-SA 3.0. The crisis at Whiskey Creek forced adaptation. Scientists at Oregon State University developed monitoring instruments called "burkolators" -- named for their inventor, Dr. Burke Hales -- that measure dissolved carbon dioxide in seawater at high resolution. Originally a research t...
