Please Note:
1) Each individual timeseries plotted on the graphical river forecast can be toggled on and off by clicking the legend entry above. If the "Observed (Raw Data)" contains bad data and is toggled off, the plot will scale to the remaining timeseries.

2) At extremely low river flows, the "Observed (Raw Data)" may show readings below the lower end of the available rating table, while the "Observed (Simulated)" will only show values at the bottom of the rating table, creating a potential discrepancy between the two readings.

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.
5.0 Feet	at 5.0 feet, flooding of low lying areas adjacent to the river between Hinkley Road and Yermo. Some local erosion to the levees. Due to bank erosion the approach from the east of the Hinkley Road bridge could be in danger of being undercut. Minneola Road and Harvard Road east of Barstow could be overtopped and closed to traffic.
