Journal 64 Willow Creek (= Juckayou Wash) 1/2 miles west of exit 93 of Interstate Highway 40. Willow Creek Ranch, Wyoming Co., Arizona. Elevation 4680 ft. August 14 I arrived here at 07:30. The owner, Mr. Stuart Ruber-son of Kingman, Arizona (not a restauranteur fame), arrived at 08:00, and after a brief discussion granted me the privi-lege of conducting field studies here. His closing comment was prophetic: "We need rain, after 2 1/2 years of insignifi-cant rain on the ranch, and we're predicted to get some. I honestly hope you get rained out." Since the main ranch road to my field site was blocked by an arroyo bank collapse, I reached this destination via a circuitous but safe route. I set up both tents, installing the field work materials in the larger work tent, and my sleeping bag & backpack, etc., in the other. I made a brief survey of the riparian corridor. There was no significant change from my August, 1989 visit, except that there was no water in the creek bottom. Last year there was a discontinuous trickle and several substantial pools. This year there are only a few small puddles, with 2 exceptions. As was true last year, there is a pump replenishing a wet spot beneath some large willows near camp, and now this year is a leaky pipe taking water from below the sandy surface to the cattle pasture atop the arroyo bank. The substantial leak falls back into the stream channel as a small river-let which runs above ground only some 40-50 feet. The stream bed and riparian border are about 25 feet
