Check with Saguaro National Park. They can set you up with topos and local maps of the area. By that time, water will be somewhat scarce except for Manning Camp, at 8000', which has a permament spring and pools. I use this area as a base camp quite often and hike the Fire Loop Trail, visit Spud Rock Cabin site, Rincon Peak, Devil's Bathtub, Spud Rock, Mica Mountain, just to name a few. You'll need a camping permit, from the SNP headquarters, as well as, what I consider, the exhorbitant $6 per night fee. Have fun and let me know where you ended up and how it went!
Pack it in, pack it out!
