Bonneville Lock and Dam
As with every river, there are 2 sides, and Bonneville Dam has a visitor center on both the Oregon side and the Washington side. Both sides have recreational opportunities and historical displays (more extensive on the Oregon side). I think both are worth visiting.

We take for granted the reasons the dams were built on the Columbia River, one of which was flood control.

McNary Dam--off Hwy 730, east of Umatilla OR
The visitor facilities was closed for so long for COVID, but at last I was able to visit, and I made it with only an hour to take in the Visitor Center. Sorry that I have a fear of heights which curbed my chance to take photos from the walkway at the top of the Visitor Center. So desperate for a restroom, I was extremely grateful for the accessible facilities.
McNary Dam fishing videos included walleye, shad, steelhead, salmon, sturgeon.

I've been in a wheelchair for 30+ years. It poses some challenges for traveling. Maybe others can benefit from my experiences.
