Years ago we had a family camping trip that took in Grand Coulee Dam. In fact, we ended up seeing - I think - NINE dams, coming and going. It was a memorable trip, for a lot of reasons. The boys were obsessed with tumbleweeds, Tate won a chicken at a rodeo, and we saw more dust devils that we could count. But what really stuck in our memories was the boys' innocent overuse of word 'dam'. You know... as we waited for a guide, "When is the dam person coming, mom?" (Chuckles from the rest of the crowd.) Or, later, "I really liked the dam tour!" Kinda took on a life of its own :0)
Well, this camping trip wasn't really planned for dams, but we saw quite a few!
The top two pics are below and above the dam by the campground - Rocky Reach Dam.
The middle pic is on up the Columbia - don't have my map handy to remember the name.
The bottom two are at Diablo and Ross Lakes.
