Yep. That's the place to park. There are a few others down that road.
There is only so much water in AZ. We all use it at the same time for everything.

Willow Springs Lake might be open when you are are there. You can make it there and back if you leave in the morning. It has all sorts of critters in it Stocked and otherwise. Use crayfish patterns and black things. Mostly wets but the occasional mosquito styled dry will work too.
Last time I was there they had some kind of boat rental but one can never be 100% sure season to season.

It's a bit tricky to find the road to it from the HWY. Chcek out that snazzy net-map you have there. It's like a left turn at 55mph through the mountains.

I miss it so...

Soon soon soon...
