Puget Sound, Washington
Puget Sound ( ) is a sound of the Pacific Northwest, an inlet of the Pacific Ocean, and part of the Salish Sea. It is located along the northwestern coast of the U.S. state of Washington. It is a complex estuarine system of interconnected marine waterways and basins, with one major and two minor connections to the open Pacific Ocean via the Strait of Juan de Fuca—Admiralty Inlet being the major connection and Deception Pass and Swinomish Channel being the minor. Water flow through Deception Pass is approximately equal to 2% of the total tidal exchange between Puget Sound and the Strait of Juan de Fuca. Puget Sound extends approximately from Deception Pass in the north to Olympia in the south. Its average depth is and its maximum depth, off Jefferson Point between Indianola and Kingston, is .

Swinomish Channel
The Swinomish Channel is an long salt-water channel in Washington state, United States, which connects Skagit Bay to the south, and Padilla Bay to the north, separating Fidalgo Island from mainland Skagit County.

Before being dredged, it was a collection of shallow tidal sloughs, salt marshes, and mudflats known as Swinomish Slough. The United States Army Corps of Engineers used dredging and diking to create a navigable channel, completed in 1937 during the Great Depression The Great Depression (19291939) was an economic shock that impacted most countries across the world.

Barkley was the first non-indigenous person to find the strait, unless Juan de Fuca's story was true. The strait was explored in detail between 1789 and 1791 by Manuel Quimper, José María Narváez, Juan Carrasco, Gonzalo López de Haro, and Francisco de Eliza.

Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .
