Thank you guys for the follow up. I had wondered if fishing with a dropper fly was legit in the trout parks, but sounds like it is.
I'll have to break down and try some of the glo balls under an indicator, and be patient to get the fly down deep in areas. Standing on the spillway looks like a bad idea for me. I have a healthy respect for how clumsy I can be and that looks like a good way to become a youtube sensation.
