Columbia River Temperature

Do any of you know about a web site that gives real time Columbia River temperatures? I have one site, DART river environment, but it is a little hard to use.

Penny,on the main page under pressure report,at the bottom is the current river temps.Now you can put your'5mil back on Shocked

and all you need is wind.

Here is a site that is interesting... daily temps but also shows ten year averages on the same graph. No surprise we are below normal at this point.

I can't read the dates at the bottom, which may explain why some of the data are confusing. Specifically, the 10-year average early April Bonneville Dam temp, which looks nothing like the iW data. I start sailing every year when the BD temp hits 46 degrees according to iW, and that's virtually always in early-to-mid April. No way iW's data show 50s this time of the month over the last decade, like this chart does.

???

And, in general ... BUMMER! Bonneville hit 46 a month or so early this year, so I've been drooling for wind (and decent air temps) which hasn't materialized yet for us wussy bootie deniers.

This was last year vs 10-year...this one says late April/ early May it just hits 50 (10).

That looks more like the data source iW uses.

The data source for the posted graph is the army corps. There is lots more data on the site including temps at other dams on the columbia. I expect the discrepancies are a result of where the temp is taken. In the forebay above the dam (warmer) or from the tail water below the dam where the water may have been drawn off below the surface (colder). Regardless the trend has been helpful to me over the years to see how things are or aren't heating up.

Quiff, I wasn't sure what you meant by the main page, but I did finally find the pressure report and found the temperature after I clicked on that. Thanks! I am glad a few of the chair lifts are still running, 48 is too cold for me

check out this site ...

There's not a lot of range between forebay temps and tailwater temps, but you can pick your dam and do some extrapolation about where you sail, how close it is to a cold influx from the Hood or White Salmon, etc. 50-52 is about the best you can hope for these days. Make your jibes!
