Facts & Myths
It is the goal of the Portland District to provide the public with factual information about Tillamook Bay. Occasionally, statements are made (either by the Corps or by others) that lead to a misunderstanding of the facts. As we become aware of such misunderstandings, we will attempt to explain and clarify them on this site to enhance effective public dialog. For questions about these topics, please e-mail us.A considerable amount of inaccurate and/or incomplete information is currently being circulated about this issue.
The following misconceptions were selected based on the comments we have received:
Myth 1: The Corps has been neglecting to dredge the bar channel for nearly 30 years.
Facts: The last time the Corps dredged the bar channel was in 1976. However, the Corps can only dredge to the Congressionally authorized depth of 18 feet. Annual surveys since 1976 have shown that the channel has remained well within the18-foot depth without dredging.
Myth 2: Depth of the channel may be as low as 15 feet.
Facts: The Corps performs annual depth surveys of the navigation channel. The surveys have indicated that the channel has remained well within the congressional authorized depth of 18 feet.
Myth 3: The deteriorated state of the jetties was to blame for the hazardous conditions that caused the Taki-Tooo accident.
Facts: The cause of the Taki-Tooo accident is being investigated by the National Transportation Safety Board. The Corps received $300,000 in the fiscal year 2003 budget to study the jetties and develop plans and specifications for their repair. If money is appropriated, repairs could begin in 2004.
Myth 4: There is a considerable build up of sand and silt at the mouth of the bay, which increases surf and wave size.
Facts: The Corps performs depth surveys of the navigation channel each year. The surveys have indicated that the channel has remained well within the Congressional authorized depth of 18 feet.
