| Flood Impacts | |
| 15.0 Feet | Record flooding at Farad and near record to record flooding on the entire mainstem Truckee River. Disastrous flooding of buildings,roads and bridges in the Verdi/Mogul area and downstream. Transportation is nearly cut off in all directions to and from Reno/Sparks. |
| 14.5 Feet | Flood disaster from Boca downstream to Nixon. Near record flooding of buildings, roads and bridges in the Verdi/Mogul area. Transportation in and out of the region extremely difficult. Similar to record flood on November 21 1950. About a one in 100 chance of being exceeded during any given year per USGS estimates. |
| 14.0 Feet | Severe near record flooding from Boca to Mogul with extensive damage to low lying structures along the river. Regional transportation severely affected with many major roads flooded or damaged. Not quite as severe as the record November 21 1950 flood. |
| 13.5 Feet | Major flooding with extensive damage to roads, bridges and structures from Boca to Mogul, especially in the Verdi/Mogul area. Transportation becomes very difficult and most major roads and highways in the area are flooded, including Interstate 80. Exceeding the level and impacts from the January 1997 flood. |
| 13.0 Feet | Major flooding from Boca to Mogul. At these flows significant damage should be expected to low lying roads,bridges and structures along the river ,especially in the Verdi/Mogul area. Transportation is significantly affected including flooding along portions of Interstate 80. Impacts roughly similar to the flood of January 1997. |
| 12.5 Feet | Expanding moderate flooding from Boca to Mogul. Damage to roads, bridges and low lying buildings, especially in the Verdi/Mogul area. Transportation affected with many road closures. Impacts approaching, but not as severe as January 2 1997. |
| 12.0 Feet | Moderate flooding from Boca to Mogul, especially to trailer and public parks in the Verdi/Mogul area along the river. Some damage to roads,bridges and low lying structures in the area. |
| 11.5 Feet | Minor to moderate flooding from Boca to Mogul, especially to trailer and public parks in the Verdi/Mogul area along the river. |
| 11.0 Feet | Flood stage. Minor lowland flooding in some locations from Boca to Mogul, especially parks and low lying terrain in the Verdi/Mogul area. Similar to the 12/31/2005 peak. |
| 10.5 Feet | Minimal nuisance flooding of low lying areas from Boca to Mogul,but near bankfull in portions of the Verdi/Mogul area. Similar to the 1/8/2017 peak. |
| 10.0 Feet | Monitor Stage, No flooding from Boca to Mogul, including the Floriston and Verdi areas. This level is near the histoic maxiumum observed spring snowmelt flows. |
| 9.0 Feet | No flooding from Boca to Mogul, including the Floriston and Verdi areas. Similar to the 4/7/2018 peak. |
| 8.5 Feet | No flooding from Boca to Mogul, including the Floriston and Verdi areas. Near this leve releases from Prosser, Boca, and Stampede Reservoirs are cut to reduce high flows at Reno. Near the highest snowmelt flows in May of 2023. |
