Waterfall below Big Fork Knob
If you look carefully enough up this seepy drainage when the leaves are off, you can see a cliff face at the end of it. That got my suspicions up, and so I slogged up the "creek" one day. Sure enough, there's a waterfall coming over that cliff face, but it's super tiny - about as much water as your garden hose can produce with a kink in it. It would be just a wet patch during anything but very rainy weather. Still, if you hit this area after a gully-washer, it might be worth investigating. Otherwise I wouldn't waste the time.
Located beside Stony Fork Road. From the National Forest entrance, drive up to the first set of switchbacks (first left, then right). The right-hand switchback is built where two drainages come together. It's located uphill of the road a few hundred yards, in the drainage just south (uphill) of the tip of the switchback.
I'm just putting this online for documentation purposes; it's probably a waste of time to try to find this one.
