WASHOE COUNTY REGIONAL FLOOD RESPONSE ACTION PLAN Appendix C: History of Flood Events
C-1
Appendix C History of Flood Events To inform future flood extent estimation, a brief study was performed by E & E to better understand the antecedent conditions associated with previous major flood events within the region.
IMPORTANT: Major floods serve as a benchmark to plan against, with the knowledge that past conditions are not guaranteed to be repeated in future events and a number of other factors should be considered, including potential debris jams, seasonality, and changing future conditions.
The following major floods are profiled in this appendix:
January and February 2017 December 24, 2005 to January 3, 2006 December 16, 1996 to January 6, 1997 February 11 to February 20, 1986
Measurement of flood extent for these events took into account many of the factors outlined in Section 1.2.2 (Potential Factors Impacting Flood Severity) of this Regional FRAP and snapshots of many of these factors are outlined below.
1 Historic Rainfall
An analysis of rainfall data provided by the PRISM Climate Group at Oregon State University, combined with precipitation frequency estimates provided by the National Oceanic and Atmospheric Administration indicated that the region’s historic flood events coincided with long-duration precipitation events. Both datasets were pulled from the Reno-Tahoe Airport. Most of the above-documented flood events aligned with near 100-year or greater storms on durations over 10 days. However, on shorter duration scales, these storms were closer to 10–25 year events. Refer to the Historic Rainfall Dataset and accompanying Precipitation Frequency Tables for additional detail.

2 January and February 2017 Flooding
Record-breaking rain and snow resulted in flooding, power outages, avalanches, road closures, and evacuations due to unsafe conditions.
Declaration of Emergency on February 23, 2017. Road closures:
o Major Roads: Highway 431/Mt. Rose Highway (avalanche, flooding) Interstate 80 (whiteout conditions) U.S. Highway 50 (heavy rain resulted in boulders falling onto roadway) U.S. 395 at Cradlebaugh Bridge in Carson Valley (flooding)
o Minor Roads: Many smaller roads were closed due to standing water Observed rainfall peaks: The 2017 storms peaked in terms on the Precipitation Frequency as a
greater than 1,000 year 60-day storm on March 1, 2017, with 11.57 inches of precipitation measured for the previous 60 days.

4 January 1, 1997 Flooding
Flooding was due to a large snowpack (more than 190 percent of normal) coupled with a subtropical storm system that brought warm rain.
Reno airport closed due to 3.5 feet of water, stranding 1,000 travelers. No injuries or deaths reported. Observed rainfall peaks: The Great Flood of 1997 interestingly only peaked as a slightly greater
than 25-year recurrence 60-day storm on January 26, 1997, with 7.11 inches of precipitation measured for the previous 60 days. However, if we dig deeper into the precipitation data, we will find that rolling totals of 1- and 2-year precipitation totals show that water year 1997 was wetter than any year between 1981 and the present, other than 1984 and 2017. No precipitation frequency models were available to measure the frequency interval of these durations of storms.

5 February 1986 Flooding
$17 million in flood damage in the Truckee Meadows and Carson City. Two known fatalities as a result of the flooding. Five counties in Nevada, including Washoe County, declared federal disaster areas. Ranked as the wettest February on record at that time. Over 27 inches of precipitation received in February of that year. Observed rainfall peaks: The February 1986 storm’s rainfall measured as the strongest storm to
affect the region for the dataset rom 1981-present. The storm measured as a greater 1,000-year recurrence interval as a 7-, 10- 20-, 30-, 45-, and 60-day storm.

High Hazard Avalanche Areas
The Avalanche Hazard Study, prepared for the County in 1993, identified the following high hazard avalanche areas (areas where avalanche could damage standard wood frame structures and/or busy automobiles):
The Third Creek Drainage is located on the southern slope below Rose Knob Peak and Mud Lake. During the field study conducted, the following two large starting zones were identified in this area, each of which is capable of accumulating large amounts of snow and producing large destructive avalanches that can travel long distances.
From an elevation of 9,600 feet, the Rose Knob Peak avalanche path falls a vertical distance of 2,460 feet to elevation 7,140 feet at SR 431. Slope angles range from 35 degrees near the top to 4 degrees just above the highway. The average slope angle from the top of the study slope to the highway is 18 degrees. The top 280 feet is a large, open, southwest-facing bowl with an average slope angle of 33 degrees, and its ground surface is mostly loose scree and talus.
From an elevation of 9,140 feet, the Mud Lake avalanche path falls 2,000 feet to elevation 7,140 feet, also at SR 431. Slope angles range from as much as 40 degrees near the top to 4 degrees just above the highway. The top 1,140 feet consists of three shallow, open, southwest-facing drainages. Ground surfaces there are mostly loose scree, which will not anchor the snowpack even in shallow snow.
The southeast-facing slope at the Third Creek drainage, northwest of the end of Jennifer Street is steep enough to produce avalanches and may receive heavy amounts of snowfall. While large amounts of snow can be expected to accumulate on this slope when storm winds are from a westerly direction, storm winds from a more southerly direction can be expected to scour much of this slope above elevation 7,840 feet. From an elevation of 8,280 feet, the study slope falls a vertical distance of 915 feet to elevation 7,320 feet at the Third Creek drainage. Slope angles range from 37 degrees near the top to near 0 degrees at Jennifer Street. The average slope angle from the top of the study slope down to the Third Creek drainage area is 21 degrees.
The Mount Rose Ski Area, located on the eastern slope of the Carson Range of the Sierra Nevada Mountains, contains several slopes which are prone to avalanches. The Chutes, including Beehive, consist of 40- to 55-degree slopes over 1,000 feet long on a north-facing slope.
The west-facing slope east of Sand Harbor is steep enough to produce avalanches and may receive heavy amounts of snowfall. While large amounts of snow can be expected to accumulate on this slope when storm winds are from a southerly direction, storm winds from a more westerly direction can be expected to scour much of this slope. From an elevation of 8,160 feet, the study slope falls a vertical distance of 1,910 feet to elevation 7,250 feet near the lake level. Slope angles range from 37 degrees near the tope to near 0 degrees at the lake. The average slope angle from the top of the study slope down to the lake level is 21 degrees. The top 1,170 feet has an average slope of 30 degrees, and its ground surface is mostly loose sand with some low brush and scattered trees.
The Crystal Bay avalanche path is located on the southeastern slope of Peak 7,350. During the field study several small starting zones were identified in this area, which are capable of accumulating large amounts of snow and producing large destructive avalanches that can travel
long distances. From an elevation of 6,320 feet, the larger southern portion of the slope has a vertical drop of 1,100 feet to elevation 6,220 feet at Lake Tahoe. The average slope angle from the top of the study slope to the edge of the Lake is 23 degrees.
Injuries, Deaths, and Economic Impacts of Avalanches between 1969 and 2015 One death was reported in January 1969 at the Mount Rose ski area. Seven injuries and two deaths were reported after an avalanche occurred in a closed area near
Mount Rose ski area in 1972. A severe avalanche occurred in February 1986 in the Third Creek Area. An avalanche occurred on December 1997 on Mount Rose Highway from an explosive trigger in
the Beehive area of the Chutes. The highway was closed for the trigger event. The only damages were to two vehicles belonging to employees of the resort who arrived earlier that morning and drove into the debris pile while trying to leave. (Source: NOAA National Data Center 10/30/2014 and Mike Ferrari Mount Rose Ski Patrol 01/25/2015, as cited in Washoe County 2015)
An avalanche fatality occurred in December 2002 at the Mount Rose Ski Resort in the Chute area, which was closed at that time and not part of the developed ski area.
Avalanche advisories were issued in March 2006 for the Crystal Bay Subdivision and Third Creek area.
A resort employee was injured during avalanche mitigation efforts in the Chutes area of Mount Rose ski area in 2007.
