With being in Scottsdale, Bartlett is great lake for crappie if you want to make a quick trip. You can still find them during the day, but the water temp is going up and they're getting deeper. Night fishing is going to be the way to go. With how low the lake is right now, I would suggest hitting the lake during the day and getting familiar with it before going out at night.
For a good full day trip, Roosevelt is great.
