Can Someone Please Direct Me to the New Old Henford River?

For the very first time, just yesterday, I had a Sim take up a couple of challenges. Errands. This after he had his girlfriend accompany him to the festival. She kept urging him to help out. So, he spoke to the Sim in charge of the festival (I think she's the mayor or something and accepted the errand of Getting to know the town of Finch(something or other). Besides having to find some spicy mushrooms, he's also supposed to bring her a fish from the New Old Henford river. But, where it it? I took him to 'forest' area Volpe? And he found a body of water in which he fished. He caught three fish, but wasn't credited with achieving this goal. I can only surmise that a) it was the wrong river or b) this challenge is borked. If you simply click on the river, no name is given. I'm lost. Lost for dayz. (And that misspelling was done on purpose.)

If any kind soul out there can please direct me to the river, I would appreciate it. Also, why can't we click on the Bramblewood? and send our Sim there? (As you can clearly see I'm names-challenged.)

Please, and thank you, in advance for any and all help. :)
