Navigation and Hydrosurveys

Navigation locks

General Navigation Lock Information
Safe Lockage Policy For Recreational Craft (.pdf) on the Columbia and Snake Rivers should be reviewed by all recreational vessel users planning on using the navigation locks.
How To Lock Through (.pdf) brochure provides instructions for recreational boaters on using navigation locks operated by the Corps of Engineers.
33 CFR 207.718 (.txt) is the Code of Federal Regulations for Columbia & Snake Rivers Navigation locks.
33 CFR 207.680 (.txt) is the Code of Federal Regulations for Willamette Falls Navigation lock.
Recreational Vessel Lockage Schedules

The Summer Recreational Vessel Lockage Schedule will be in effect from May 15 through Sept. 15, 2011, at Bonneville, The Dalles and John Day navigation locks on the Columbia River.

The Winter Recreational Vessel Lockage Schedule will be in effect Sept. 16, 2011, to May 14, 2012, at Bonneville, The Dalles and John Day navigation locks on the Columbia River.

Willamette Falls Locks closed Sept. 20, 2010. The district has not received funding to operate the locks for public use in 2011.

Maintenance crews will try to accommodate a limited number of commercial lockages that coincide with regularly-scheduled maintenance activities, and lockages requested by proper authorities to deal with emergency situations.

Hydrographic surveys

These data files represent the results of surveys made on the dates indicated and can only be considered as indicating general conditions existing at that time. Please note the survey data is referenced to State Plane Coordinates North American Data 1983 with sounding reference below Mean Lower Low Water or Columbia River Datum, where applicable, in U.S. Survey Feet.

General information about hydrosurveys
Portland District's hydrographic surveys cover an area from Cape Disappointment on Washington's southern coast to the Chetco River on Oregon's southern coast and from the Pacific Ocean on the west to McNary Dam on the east. More than 400 miles of navigational channels include coastal entrances, deep and shallow draft harbors and river channels. Using state-of-the-art data acquisition and differential global positioning systems, four full-time, in-house survey crews and one contracting crew are able to monitor dynamically active reaches of the navigation channels for shoaling or scouring each month.
These hydrographic surveys represent the latest data available and can be viewed in 2 formats:
channel-line or cross-line.
Monthly channel-line surveys of this area are updated on our web site soon after being received at the District Office. Annual cross-line surveys are usually updated on the website by Feb..
We also have channel-line surveys of the Oregon coastal projects from Tillamook Bay on Oregon's northern coast to the Chetco River on its southern coast. These surveys are usually updated annually--see below.

Channel Status Reports

**Each channel status report below represents the controlling depth per channel quarter of all the District's navigational channels for surveys made on the dates shown and can only be considered as having indicated the general conditions existing at that time.**

The usual update of the reports will be once a month. Date of latest update: December 28, 2011. Click here for methodology diagram of extracting controlling depths.

Northern Oregon coast hydrosurveys

Channel-line surveys of the Oregon's northern coastal projects from Tillamook Bay to Yaquina Bay.

The information contained in the PDFs and XYZ data files represent the results of surveys made on the dates indicated and can only be considered as indicating general conditions existing at that time.

Channel-line surveys are survey lines which run parallel to the channel, 7 lines across, 150 feet apart.

Southern Oregon coast hydrosurveys

Channel-line surveys of southern Oregon's coastal projects, from Siuslaw River to the Chetco River.
Crossline surveys are only done in Coos Bay for south coast.

The information contained in the PDFs and XYZ data files represent the results of surveys made on the dates indicated and can only be considered as indicating general conditions existing at that time.

Channel-line surveys are survey lines which run parallel to the channel, 7 lines across, 150 feet apart. Cross line surveys are lines that run perpendicular to the channel, bank-to-bank and are generally 500 feet apart.
Survey data is referenced to Oregon South State Plane Coordinates North American Data 1983 (NAD 83) with sounding reference below Mean Lower Low Water (MLLW) in U.S. Survey Feet.

Columbia River hydrosurveys (Mouth to Vancouver)

Columbia River PDFs, XYZ data and contours

Columbia River surveys are channel-line and cross-line surveys of the Columbia from The Mouth of the Columbia to Vancouver Turning Basin. Channel-line surveys are survey lines which run parallel to the channel, 7 lines across, 150 feet apart. Cross Line surveys are lines that run perpendicular to the channel, bank-to-bank and are generally 500 feet apart.

The information contained in the PDFs and XYZ data files represent the results of surveys made on the dates indicated and can only be considered as indicating general conditions existing at that time.
Survey data is referenced to Oregon North State Plane Coordinates North American Data 1983 (NAD 83) with sounding reference below Mean Lower Low Water (MLLW) in U.S. Survey Feet to Miller Sands where the sounding reference changes to Columbia River datum (CRD).

Columbia River hydrosurveys (Vancouver to The Dalles)

Columbia River PDFs, XYZ data and contours

Columbia River surveys are channel-line and cross-line surveys of the Columbia from The Mouth of the Columbia to Vancouver Turning Basin. Channel-line surveys are survey lines which run parallel to the channel, 7 lines across, 150 feet apart. Cross Line surveys are lines that run perpendicular to the channel, bank-to-bank and are generally 500 feet apart.

The information contained in the PDFs and XYZ data files represent the results of surveys made on the dates indicated and can only be considered as indicating general conditions existing at that time.
Survey data is referenced to Oregon North State Plane Coordinates North American Data 1983 (NAD 83) with sounding reference below Columbia River datum (CRD) in U.S. Survey Feet to above Bonneville Dam where the soundings are referred to minimum operating pool elevation.

Columbia River sidechannel hydrosurveys

Columbia River Side Channel PDFs and XYZ data

Columbia River Side Channel surveys are channel_line surveys of the projects adjacent to the Columbia River such as ports or tributaries that have a Federally authorized channel.
Channel-line surveys are survey lines which run parallel to the channel, 7 lines across, 150 feet apart.

The information contained in the PDFs and XYZ data files represent the results of surveys made on the dates indicated and can only be considered as indicating general conditions existing at that time.
Survey data is referenced to Oregon North State Plane Coordinates North American Data 1983 (NAD 83) with sounding reference below Mean Lower Low Water (MLLW) in U.S. Survey Feet to Miller Sands where the sounding reference changes to Columbia River datum (CRD).

Hazards to navigation

Program description
The United States Army Corps of Engineers and the United States Coast Guard have authority for the removal of vessels and other hazards to navigation from the waterways of the United States. In general, the USCG is the primary agency that will identify and remove a hazard to navigation; however, the USCG may ask USACE for assistance. The USCG or USACE may remove the hazard at the owner's expense. Local port districts, city, county, and state agencies may also take legal action against the owner for removal of a hazard to navigation within their jurisdiction.
To contact the Portland District regarding Hazards to Navigation, send an email with the subject "Hazards to Navigation" to the Hazards to Navigation Coordinator.
Hazards to Navigation authority
Authority for removal of hazards to navigation by the U.S. Army Corps of Engineers is referenced in Sections 15-20 of the River and Harbor Act of 1899.
Guidelines for coordination, removal of hazards to navigation, and cost recovery between the United States Coast Guard and the United States Army Corps of Engineers are found in the following:
