| 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 | |
| 10.5 Feet | Incredible flood disaster with massive and uncertain impacts in excess of the January 1997 event. |
| 10.0 Feet | Flood of record. Highway 395 in West Walker River Canyon closed for months. Massive destruction to infrastructure and economy including transportation, power, water, homes, businesses, etc. Area isolated. Near this flow in January 1997 a 6.5-mile stretch of Highway 395 completely scoured with debris from the canyon deposited in the town of Walker. |
| 9.5 Feet | Near record flooding. Area cut off as most transportation routes into area destroyed or flooded. Massive destruction of infrastructure and economy including utilities, roads, business, homes, etc. |
| 8.5 Feet | Flood disaster from Walker River Canyon through Antelope Valley. Widespread flood damage to roads, bridges, homes and structures along river. Severe damage to Highway 395 in W Walker River Canyon with the highway likely closed. Historically this flow has been exceeded only once in January 1997. |
| 8.0 Feet | Flooding near disaster levels in the West Walker Canyon and in Antelope Valley. Numerous structures flooded and roads washed out. Sections of Highway 395 likely destroyed in West Walker Canyon. Major damage to agricutural land due to erosion and destroyed diversion dams, headgates, canals and levees.
