CNRFC - Hydrology - River Guidance - Graphical RVF

*** IMPORTANT *** Week of June 16 - Website Data Outage - Due to a major computer upgrade the week of June 16, nearly all data on the CNRFC web site will not be updated. We anticipate the down time to be approximately 4 days. The latest deterministic hydrologic forecasts for official forecast points will continue to be available at the National Water Prediction Service during this time.

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
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.
