Welcome to another edition of our trivia challenge, where we test your knowledge of all things fly fishing and where you might learn a thing or two about this sport we love. This week, we’ve got 20 new questions about where famous trout rivers end up. In each of these questions, we want to know what river flows directly into another.
As expected, the performance on the last quiz was pretty spotty, with no perfect scores. One intrepid quiz-taker, Layton, scored a 95%, and Tim S. was right behind with the lone 90%. The most common score was a 55%. These geography ones are pretty tough.
The randomly chosen winner for this quiz will receive a copy of the great new book from my friend Morgan Lyle, The Fly-Fisher’s Companion.

Our last winner (as determined by random.org)—who will receive a copy of Darrell Martin’s The Fly-Fisher’s Companion—was Dave F., whose 70% put him in the top tier of scores.
So post your score below for a chance at winning a great fly-fishing book.
Good luck!
Rivers flow into other rivers. Do you know which ones?
