The diked channel on Willow Beach Wash will not convey floods of 25-year or greater recurrence interval. Serious hazards from manmade objects being moved and widespread deposition of debris from these floods should be expected. The most valuable reach is from section D to downstream of section B (pl.1). The Jumbo Wash campgrounds may be inundated by flows of 25-year or greater recurrence interval because the dikes are low or nonexistent in places. Debris hazards include dangers from manmade objects moving and extensive debris deposition, and debris deposition at the wash terminus during floods of all sizes. Of the three washes, Access Road Wash is probably the least hazardous in terms of overall potential flood and debris hazards. The ranger headquarters and the employee residences may be in hazardous locations for the 100-year or greater recurrence interval flood.
