Call AGFD and ask for MariAnn Kolozsar or Ken Branson. I don't believe they're the ones that oversee Pleasant but either one can give you the name of the person to contact. I don't have their numbers with me right now.
AGFD is responsible for water safety, etc., but the Forest Service is responsible for the repair. AGFD gives them the funds every year to keep things maintained. It's the Forest Service that's slacking.
The bumpers at Saguaro have already been repaired this year. If they need more repair, the above two people are the ones to contact again.
