Since you two took the libery of posting multiple guesses...I think I shall do the same.

1)Tillamook Bay
2)Sol Duc River
3)Columbia at the mouth of the Lewis
4)Lyre River
5)Sky at Reiter
6)Imnaha River

I looked and looked and looked for the Lyra but have yet to find it...hmmm could this a secret river that you and Bob share?? LoL

..although God knows you'll go back and edit it and change Lyra to Lyre.
