It’s great to quote a fisherman’s memory going back 50 years but that doesn’t make it factual ! I was delivering mail back in 1964 and the Great Christmas flood crested at 27.7 feet. I had a mail route in Milwaukee and the Willamette flooded about 1/3 of my route under water. Also in 1996, we had another flood that crested at 27.6 feet and caused huge damage in the hundreds of Millions as I recall. The 1964 Christmas floods led to quite a few deaths also. I witnessed mobile homes docked at the Sellwood Bridge area break loose and float down the Willamette. I was there in 1948 and witnessed the famous Vanport flood which crested at over 30 ft.as I recall. The river and Tina Bar Robert viewed in 2013 was a shadow of what it was in 1971.
Kermit,
I suspect you are relating "gage" readings and not distances above sea level. And what gage are you referring to? The Vancouver/Portland gage is located just off shore on the Vancouver side of the Columbia River and just a few hundred feet east of the I-5 bridge.
It is agreed that the Tina Bar area has a huge erosion problem. But the aerial pictures from the early 1970s can be used to estimate that erosion.
Do you know of a source for the gage readings at Vancouver/Portland in the 1971 to 1973 time frame? Also, can you clarify how the earlier readings were adjusted to put them in the WGS84 system?
Robert,
Yes I am giving a reading from the Portland/Vancouver gage which is right by the I 5 Bridge as you mentioned.
Since I’m seeing up to 24 readings in the negative, I’m assuming the river actual Sea Level high point must be in excess of the gage readings ? Going back to the 1971 to 1973 time frame might not be easy to attain. Since the present daily readings are charted by the National Weather bureau Portland’s Office, that might be a good area to start at. I guess one of the main points I wanted to make is all these rivers in the general area have had numerous
Floods over the years I’ve lived here. Some people have posted about how small the Washougal River flow is but I’ve seem it flood and cause close to $100,000 damage to my Mother In Laws home which was right on the river !
