Water is the subject of the latest Readers Photo Challenge. It covers about 70% of the Earth’s surface and is the necessary ingredient for life. Stockton and San Joaquin County abound with rivers, canals, sloughs and streams. Readers sent in photos of water that they found from the mountains to their own backyards. Here are some of their best examples. Stocktonian John Ranelletti’s photo looks like if could be the inspiration for a Japanese woodblock print. With an Apple iPhone 12 Pro he photographed his backyard koi pond on a windy day. He captured the turbulent waters creating an abstract pattern from the broken reflection of an overhead arbor and blue sky as a fish surfaced for a striking image.
