The main pond at Agua Caliente Park is looking less like a mud flat and more like an inviting oasis once again. An estimated 40 percent of the 3.5-acre pond northeast of Tucson had dried up last month as drought plagued the area — but much of the once-dry surface is now covered with at least a few inches of water. Credit recent relatively cool weather, monsoon rainfall and continued pumping of well water into the pond. Video by Arizona Daily Star reporter Doug Kreutz.
