caption_attribution_description: English: The mouth of the Siuslaw River in the Pacific Ocean at Florence, Oregon, USA.
context_page_description: The Siuslaw jetties at Florence, Oregon, in the United States, are parallel rubble-mound structures at the entrance of the Siuslaw River, bounding the north and south banks and protecting the navigation channel. The jetties extend into the Pacific Ocean, with spur jetties designed to reduce breakers and shoaling across the sand bar.
  The U.S.Army Corps of Engineers completed the jetties in 1917, and completed reconstruction and lengthening projects in 1962. USACE lengthened the jetties again in 1985, and spur jetties were added at that time to reduce shoaling and the need for dredging.
