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
19.0 Feet	Significant flows are occurring along the entire reach of the river, with flooding of adjacent farm lands north of victorville. The levees are threatened in the more densely populated areas of hesperia, victorville, and helendale, with overtopping possible in areas where vegetation or debris chokes the channel.
18.0 Feet	Significant flows have likely reached helendale and points to the north, with farm lands in the river bed and adjacent areas north of victorville inundated. Rock springs road in hesperia is in danger of washing out. Some erosion of the levees can be expected in victorville and helendale.
16.0 Feet	Significant flows reach farming areas north of victorville. Minor flooding of farmland adjacent to the river bed can be expected in oro grande. Some local erosion to the levees in hesperia and victorville is possible. Rock springs road has been overtopped and closed to traffic in hesperia.
13.0 Feet	AS WATER BEGINS TO FLOW IN THE NORMALLY DRY RIVERBED. LOW-WATER CROSSINGS WELL UPSTREAM OF THIS GAGE SUCH AS ROCK SPRINGS ROAD BELOW THE MOJAVE FORKS DAM MAY BE OVERTOPPED AND CLOSED. THIS CORRESPONDS WITH A POOL LEVEL OF 3005 FT AND ABOUT 2500 CFS. RELEASES FROM SILVERWOOD LAKE CAN ADD A CONSIDERABLE AMOUNT OF INFLOW BEHIND THE DAM.
