It appears that you are not discriminatory towards catching any particular species of fish. So, here is what I recommend and this is coming from a guy who fishes highly pressured urban ponds frequently. This worked in Denver and certainly works in Phoenix. I'm teaching my 2 1/2 year old son how to fish and carry him on me with a backpack. Because I want him to see action, this is my confidence rig that seems to work everywhere!
Rig a 2" pumpkin seed Berkley Powerbait Power Grub on a small roadrunner jig. Use a medium light rod with 6# test and slow roll the lure right off the bottom with random pauses. I showed a buddy new to fishing last week how to catch trout at an urban pond by slowing jigging a grub along weedlines. All the bait dunkers were watching us catch a limit. I use ultralight set ups all winter because it's appealing to largemouths, bluegills, saugeye, walleye, yellow bass, crappie, stocked trout, channel catfish, and an occasional common carp.
From Spring thru Fall, when the shad start moving in, I'll transition to a 3" white Berkley Powerbait Power Grub using a slightly larger underspin and catch largemouth bass up to 4 lbs in the same highly pressure waters. Senkos, tubes, inline spinners, list goes on and on..........they all work. However, don't give up on the grub.
I've been introducing a lot of people to fishing lately and a grub keeps people engaged. Whether it be from the bank or from my tandem kayak, it's beyond effective!
Once you've mastered the grub, then you can incorporate the Gulp! Alive! 2.5" Black Shad and learn to use that bait with a drop shot, slip bobber rig (missed a 28" walleye in Colorado using this technique from shore), and yo yo retrieve with an underspin. I swear up and down that if I only had a variety of grubs, an underspin, and jar of Gulp! Alive! Minnows..........I would be able to catch fish for the rest of my life.
