The river is back again near the Wendy and Potrero trailhead to the Wendy Trail in Rancho Sierra Vista/Satwiwa. It was here a month ago, dried up quickly, and of course now is back. This and other water flows near the Satwiwa Center, "Lake Satwiwa" near the parking lot and more captured here. Best to stay off the trails until they dry up a bit though I did tiptoe down the side of the Wendy Trail to capture the water flow.
