The April 1983 landslide at Thistle, Utah, created a 200-ft-high (60-m-high) blockage of Spanish Fork canyon that caused disastrous flooding of the Thistle creek and Soldier Creek valleys upstream.  The flooding caused by the landslide required relocation of a major highway and railway.  An emergency spillway and diversion tunnels were constructed to drain

Eaton Wash (blue arrow) is a channel that flows along the mountain front and empties into the Eaton Wash Reservoir (red arrow). The Eaton Wash Dam and Eaton Wash Reservoir help to control flood waters and trap sediment that shed from the range front during the rainy season in southern California.
