You asked (or at least Wrangler did), and I heard. And I have (finally, sorry for the delay) responded ...
And thus I present ... a valley downriver from the dam. Again, this is now available in both 'original' and 'the dam is out' flavours. A quiet(ish) river valley, with orchards to the west, and planted fields (I like to think of these as vineyards) to the east. There is a settlement in the middle of the valley, at the confluence of the main river with a smaller tributary, which is followed by a major road. There is also some newer housing, built (foolishly, as it turns out) on the floodplain of the river. The valley sides are, in the main, lightly wooded (more lightly, in fact, than the lake sides).
(I'm afraid I was slightly lax, and didn't check that enough water had been lost from the dam to guarantee raising the height of the river by 1 level. Please assume that this is fine, and that there is possibly an accidental dam just off the map to the south-east, probably made of fallen trees and destroyed building components, causing the river to have backed up. There has been enough flow of water to take out one of the smaller bridges, as well as the buildings and many of the woods on the flood plain.)

And, to give an idea of what these look like combined with the matched dam maps, to make a 64x136 board ... it's like this:
