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.
Key to abbreviations used in Ives data:
|feet of water depth over the gauge
|feet (USGS gauge)
*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.
- * For these two months only, the elevation of gauge 2 above mean sea level
was 14.55 feet.
- * For data prior to January 2007 contact the FPC data staff.

- 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.

- 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

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 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
