Trestle Bay ("Jetty Lagoon") ...
The 1.5-mile-long Trestle Bay (officially "Jetty Lagoon") is located on the eastern side of Clatsop Spit, between Point Adams and the tip of Clatsop Spit.

From the NOAA Technical Memorandum NMFS-NWFSC-39 (January 2000):

"Trestle Bay is 11.3 RKm (river kilometers) upstream from the mouth of the Columbia River in Oregon. The 244-half-acre bay consists of shallow subtidal and intertidal mudflats and intertidal marsh habitats. Trestle Bay formed as a result of the initial construction of the Columbia River south jetty which took place from 1885 to 1895. Sand accumlation around the jetty created the bay, which is surrounded by land on the west, south, and east sides and separated from the mainstem of the Columbia River by a 2,683-meter rock jetty along the north side. ..."

"In August 1995, the jetty was modified by removing a 152-meter section of rock, creating an unobstructed passageway between the bay and the lower Columbia River estuary. This allowed better flushing and made Trestle Bay available as foraging habitat for many marine and estuarine fishes and shellfish, and ultimately reestablished the bay as an integral part of the lower Columbia River estuarine ecosystem. ..."

Jetty Lagoon was not named until 1979. Early suggestions for naming were "Concomly Lagoon" and "The Lagoon". The U.S. Board of Geographic Names made "Jetty Lagoon" official in 1979. Common usage (2011) calls the bay "Trestle Bay".
