Ives Island Data

REAL TIME Island Water Elevation and Water Temperature Data

These REAL TIME data are downloaded directly from a USGS stage gauge near Vancouver, WA (#14144700), one USFWS temperature and elevation gauge near Ives Island, and from a USACE ftp site where Bonneville Dam flow and project tailwater elevation data is stored.  This data is not corrected and may vary significantly from the final USACE or USGS numbers.  Corrected Bonneville powerhouse tailwater data is available on our flow query. Final USGS gage data is not available on USGS's website so you would need to contact them. Occasionally, these gages will experience technical difficulties which may result in missing data.  Please be assured this is generally the problem if records are missing and the FPC is aware of the problem and will update the files as soon as the stations are operational. Don't hesitate to contact FPC data staff if you have any questions or concerns.

NOTE: The Ives Island gauge and data are currently unavailable due to hardware issues. There are data through 4/9/07.

Key to abbreviations used in Ives data:

*Use this handy webpage to convert to Fahrenheit http://www.wbuf.noaa.gov/tempfc.htm or use this formula F= (C*1.8)+32 which can be converted to use in excel as =SUM((A2*1.8)+32) where A2 contains the temperature in Celsius.

• Gauge 1 is found at: Lat 45°37'36.24", Long 121°59'09.13", near the upriver terminus of the channel on the north side of Ives Island.  The elevation of this gauge is 13.27 ft.  (Lat. and Long. Datum is NAD 83, error +/- 22 ft for both gauge locations.  The vertical datum used to calculate mean sea level for both gauges is NAVD88). 
  Ives Gauge #1 is missing data from 5/25/01 to 6/26/01 and from 09/10 to 10/10.  Ives Gauge #1 is missing date from 11/29/01 to 01/23/02.
• Gauge 2 began operation at 1600 on February 23, 1999 and is found at: Lat 45°37'30.39", Long 121°59'43.81", on Ives Island across from the mouth of Hamilton Creek.  The elevation of gauge 2 measured from mean sea level is 12.955 ft.  The vertical datum used to calculate mean sea level is NAVD88. The gauge was elevated to this height when re-installed in November of 1999.  Gauge 2 was  flooded-out and removed in June of 1999.  From February 1999 through June 1999, the elevation of gauge 2 was 13.525 feet above mean sea level.  Ives Island Gauge number 2 was not working between 1/11/00 and 2/1/00. The depth measurement section of gauge 2 began to work properly again on 2/2/00 at 1:00am, though the temperature section of gauge 2 is not working properly at this time. Ives Gauge #2 was removed on 4/19/01.
• Vancouver elevation data is from USGS gauge number 14144700, which is located on the Columbia River at Vancouver, WA.   This is a National Weather Service stage gage.  Datum of the gage is Columbia River Datum, add 1.82 feet to correct to mean sea level.  The vertical datum used to calculate mean sea level in this case is NAVD29.   LOCATION.-- Lat 45°37'15", Long 122°40'20", in NE1/4,NW1/4 sec. 34, T.2 N.,R.1. E., Clark County, Hydrologic Unit 17080001, near right bank in control house of Interstate Highway 5 bridge at south edge of Vancouver, 5.0 miles upstream from Willamette River, and at mile 106.5.  From 2/12/99 at 900, through 2/13/99 at 2400, the Vancouver Gauge Data was not available due to USGS upgrading their data collection system.  On 2/10/99 from midnight through 8:00am, on 2/11/99 from midnight through 2:00pm, and on 2/28/99 from 2100 to 2400,  some data is missing due to a data collection system malfunction.
• Bonneville hourly flow data forebay and tailwater elevations are from the US Army Corps of Engineers CAFE report number 38.
• Data Updates: This web site automatically updates every 2 hours, at 30 minutes past the hour, however updates do not always occur on that schedule.  Bonneville flow data is updated every 4-24 hours, depending on availability.  Vancouver gauge data is updated every 2-4 hours, and Ives Island gauge data is updated every 2-8 hours.
• Technical:
  • If you suspect the data you see in the ASCII table is not current, your browser is probably holding old data in it's cache.  Internet Explorer users should go to their browser's "Tool" menu, then choose "Internet Options", and click on "Delete files" in the temporary internet files section.   Netscape users should go to the "Edit" menu, and choose "Preferences".  Then they should click on the little plus sign "+", next to the word "Advanced" in the list on the left.  Select "Cache" next, and then choose "Clear Memory Cache" and "Clear Disk Cache" to delete the troublesome older  versions.  
  • Minor issue reported to occur with version 4.x or 5.x of Internet Explorer is that the user is sometimes asked for a password and whether they want to "logon as anonymous" when clicking on a hyperlink to the FPC ftp site. If you are asked for a password, just select "logon as anonymous" and click "OK," no password is required.
