Water in the desert is hard to find, but at Barker Dam, there is a permanent supply of water. Hubby and I love to stop there and hike back to the dam and view the water level. This January, after a snow storm, we hiked back to it while there was still snow on the ground. I always enjoy this stop at Joshua Tree National Park and if you travel there, make sure you stop at Barker Dam! Watery Wednesday for March 8, 2011.
