Impacts - E19 Information
8.5 Feet	No flooding from Boca to Mogul, including Floriston and Verdi areas. Near this level, releases from Prosser, Boca, and Stampede Reservoirs are cut to reduce high flows at Reno. Near the highest snowmelt flows in May of 2023.
9.0 Feet	No flooding from Boca to Mogul, including Floriston and Verdi areas. Similar to the 04/07/2018 peak.
10.0 Feet	Monitor Stage. No flooding from Boca to Mogul, including Floriston and Verdi areas.
10.5 Feet	Minimal flooding from Boca to Mogul, but near bankful in portions of the Verdi/Mogul aera. Similar to the 01/08/2017 peak.

Similar to record flood on 11/21/1950. About a 1 in 100 chance of being exceeded during any given year per USGS estimates.
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.
