I thought the Sellwood Bridge was the most upstream in the Portland city limits? This article says its the Ross Island.

Good catch. Thanks for posting a note. I worked on the bridge section a couple of years ago, and I don't remember what I was looking at vis-a-vis the Ross Island Bridge and the total number of bridges. I'm traveling, and I don't have my bridge books with me. Just working from memory, though, it seems to me that you are right. Sellwood is part of Portland. Listing the bridges from memory, starting at the downstream end, I can name St. John's, Fremont, Broadway, Steel, Burnside, Morrison, Hawthorne, Ross Island, and Sellwood. That's only nine. Am I missing any? At least temporarily, I changed the article to give the Sellwood Bridge credit for being the furthest upstream in Portland, and I hedged on the total number of Portland bridges. Anyone with better info might want to tweak this further.

The Sauvie Island Bridge crosses the Multnomah Channel rather than the mainstem, and it seems to be beyond the Portland city limits. I restored the 10-count with the "highway" qualification.

For the record, that railroad bridge mentioned above (without name) by Jsayre64 is the Burlington Northern Railroad Bridge 5.1. Its Wikipedia article is actually more developed than those of any of the road bridges (and is B-class, whereas none of the 10 road bridges' articles has even been assessed as more than Start-class, although two or three probably now qualify now as C), but I am not suggesting it should be mentioned in this article. The general public has much less interest in railroad-only bridges, and few Portlanders could even identify this bridge by name, so it probably does not merit mention in the river article.

Third paragraph in the section 'Course' says I-5 and US-99, it should be I-5 and State Route (SR)- 99. I found this reference 'http://www.gbcnet.com/ushighways/US99/index.html' and of course, this is what the Wikipedia article itself says about US-99. Fourth paragraph in the introductory section states that the dams on the river are for hydroelectric and irrigation. The 8 dams near Eugene don't have power plants nor any works used for irrigation. These are strictly for winter flood control and summer recreation. This is the Army's pamphelet 'http://www.nwd-wc.usace.army.mil/pdf/wmbroch.pdf' which really confirms both statements.

Good catches. You are mostly correct. Route 99 is not a U.S. highway anymore, so what follows the river would be Oregon Route 99, Oregon Route 99E, and Oregon Route 99W. Many of the dams near Eugene produce electricity; I know that from living in the valley. But you are right about irrigation. I haven't heard of the dams serving that purpose and that USACE document doesn't support the claim. I will fix these things in just a second.

Having grown up near Eugene, I'd like to second your comment about the dams producing electricity and provide a corroborating example and source, the Lookout Point Dam on the Middle-Fork http://www.nwd-wc.usace.army.mil/report/lop.htm. That same source seems to indicate that the dam was at least built with irrigation purposes in mind. I have no idea whether it is still used for this purpose.

Possibly, but it must not be large-scale. But there are some farms nearby, in and around Pleasant Hill and Dexter.

A quick Google search shows that yes, indeed, some of the stored water is used for irrigation, but not much.

I would also point out that while no great amount of space has been devoted in this article to logging, it's not strictly true that the article ignores it entirely. The "Flora and fauna" section begins with: "Over the past 150 years, a significant change for the Willamette River has been the loss of its floodplain forests, which covered an estimated 89 percent of a 400-foot (120 m) band along each river bank in 1850." Part of the difficulty in writing an article that is comprehensive but not overly detailed is to decide how much to say about any particular relevant topic. One way to deal with logging along the Willamette in a more detailed way would be to create a separate article that we could link to from this article. If you'd like to undertake that, 69.138.223.87, others who are interested in the topic would probably be willing to help.
