15	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. Transportation is nearly cut off in all directions to and from Reno/Sparks. At about 19000 cubic feet per second...less than a 1 in 100 chance of being exceeded any year per USGS estimates.
14.5	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. At about 17800 cfs...similar to record flood on November 21 1950. About a one in 100 chance of being of being exceeded during any given year per USGS estimates.
14	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. At about 16700 cfs...USGS estimates the chance of exceeding this flow about one in 85 chance any year. Not quite as severe as the record November 21 1950 flood.
13.5	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. Slightly worse impacts than the January 2 1997 flood. About 15600 cfs...about a one in 70 chance of being exceeded any year per USGS estimates.
13	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...portions of Interstate 80 flood. At 14600 cfs...the USGS estimates that this flow has about a one in 60 chance of being exceeded during any given year at Farad. Impacts would be similar to the floods of January 2 1997 and December 23 1955.
12.5	Moderate to major 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 worse than February 1 1963 and December 23 1964 floods at Farad...but not as severe as January 2 1997 or December 23 1955 floods. At 13600 cfs...the USGS estimates this flow has a one and 50 chance of being exceeded during any given year at Farad.
12	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. Similar impacts to the floods which occurred on February 1 1963 and December 23 1964 at Farad. At about 12600 cfs...the USGS estimates that this much flow has about a one in 40 chance of being exceeded during any given year at Farad.
11.5	Minor to moderate flooding from Boca to Mogul...especially to trailer and public parks in the Verdi/Mogul area along the river. Similar impacts to the February 1 1963 and December 23 1964 floods at Farad. At about 11700 cfs...the USGS estimates that this much flow has a one in 30 chance of being exceeded during any given year at Farad.
11	Flood stage...about 10700 cfs. Minor lowland flooding in some locations from Boca to Mogul...especially in the Verdi/Mogul area. The USGS estimates that this much flow has a one in 25 chance of being exceeded during any given year at Farad.
10.5	No flooding from Boca to Mogul...but near bankfull in portions of the Verdi/Mogul area. At about 9600 cfs...the USGS estimates that this much flow has about a one in 20 chance of being exceeded during any given year at Farad.
10	No flooding from Boca to Mogul...including the Floriston and Verdi areas. At about 8650 cfs...the USGS estimates that this much flow has about a one in 15 chance of being exceeded during any given year at Farad.
9.5	No flooding from Boca to Mogul...including the Floriston and Verdi areas. At about 7700 cfs...the USGS estimates that this much flow has about a one in 10 chance of being exceeded during any given year at Farad.
9	No flooding from Boca to Mogul...including the Floriston and Verdi areas. At about 6850 cfs...the USGS estimates that this much flow has a one in 8 chance of being exceeded during any given year at Farad.
8.5	No flooding from Boca to Mogul...including the Floriston and Verdi areas. At about 6000 cfs...releases from Prosser...Boca and Stampede Reservoirs are cut so flow at Reno does not exceed 6000 cfs. The USGS estimates that this flow has about a one and 7 chance of being exceeded during any given year at Farad.
8	No flooding from Boca to Mogul...including the Floriston and Verdi areas. At about 5150 cfs...the USGS estimates this flow has about a one in 5 chance of being exceeded during any given year at Farad.
6.3	No flooding from Boca to Mogul. About 2700 cfs...the USGS estimates a one in 2 chance of being exceeded during any given year.
