Yaquina Bay is a coastal estuary with freshwater input from the Yaquina River as well as open access to the Pacific Ocean. Jetties at the entrance were constructed in 1888 to improve navigation by minimizing the effects of shifting coastal sand. The bay is spanned by the Yaquina Bay Bridge, built in 1936 to replace a ferry, and is one of the most recognizable bridges designed by Conde McCullough. The principal communities are Newport, a popular tourist destination along U.S. Highway 101, and Toledo, a small pulp mill town at the head of the bay. The name Yaquina is from the tribe of Native Americans that now live on the Siletz Reservation. Historical uses of Yaquina Bay include commercial oyster farming, fishing, and recreational clamming. Shipping became economically important when the road connecting Yaquina Bay to the Willamette Valley was completed in 1873, followed by a railroad in 1884. The Hatfield Marine Science Center is a research and education facility operated by Oregon State University in cooperation with five state and federal agencies. The facility occupies a 49-acre (20 ha) site on the south shore of the bay adjacent to the Oregon Coast Aquarium. Read more here and here.
