Flood Impacts
8.0 Feet	at 8.0 feet, levees could be overtopped leading to extensive flooding of structures and infrastructure located along the river bank off Soapmine Road and Riverside Drive in Barstow.
6.5 Feet	at 6.5 feet, Lenwood Road crossing at Mojave River potentially overtopped.
6.0 Feet	at 6.0 feet, some levees are threatened and overtopping is possible which would bring flooding to structures located near the river bank off Soapmine Road and Riverside Drive in Barstow.
5.5 Feet	at 5.5 feet, flooding of low lying areas and farmland adjacent to the river between Hinkely Road and Yermo. Due to bank erosion the approach from the east to the Hinkley Road bridge is closed. Additional erosion of the levees can be expected.
