Well after looking further in the West section I have determined this area to be what Jeepers call the Dishpan Trail. I was up there 2 weeks or so ago in my Jeep and I would rather drive my Jeep on this section than my bike.
Dishpan and Devils hole are two different places. However getting your bike through dishpan isn't as bad as it looks. Nevertheless Devils hole is further downstream from dishpan (at the bridge). It is all easy fire road getting there until the last (very short) section before you reach the end. If you have not ran 2w01 yet, give it a shot! its a great trail!
Devils Hole: 34.301258,-117.128593
Looks like you guys got some work done out there! I hope to make it up there soon to take a look at it. Creek looks like it has dropped a lot of water, still needs to drop another foot though it looks like.
