1997 Flood
The 120 mile long Truckee River has been the site of many devastating floods throughout the history of the Truckee Meadows. The floods are triggered by winter rainstorms that melt the snowpack up in the nearby Sierras. There have been a number of major floods recorded in the area since before the founding of Reno.
From Drought to Flood:
Upstream from Whitewater Park, the United States Geological Survey uses a cableway gauging station to measure water flows. Using a pressure sensor and satellite communications, these water flows are measured on a constant basis. These measurements are monitored and reviewed by hydrological technicians. This information helps the community plan for short and long-term flood situations and effectively manage the upstream reservoirs. These reservoirs (Prosser Creek Reservoir, Boca Reservoir, Stampede Reservoir, and Independence Lake) help protect against seasonally high water levels of the Truckee River. In a typical flood, heavy rain or snowfall raise the river’s waters with new stream beds being formed when the river overflows its banks.
Flooding is not an issue until you build up a city along the river banks.When it floods, sediments begin to choke the river adding sandbars, silt, rock, and logs. The river cannot change its course and since the city around it defines its shape when it does spill over its banks the water threatens property and lives.
Before Reno and Sparks were built, the river had the ability to spread out in the wetlands and meadows on the east side of the Truckee Meadows. With each consecutive flood there is more sediment and less ability for water to flow through its natural corridor. In other words, it takes less water to overflow the banks, and there is greater danger of flooding. The community has dedicated continuous efforts to protect property while not damaging our living river system.

The New Years Flood:
One of the largest of these floods was the New Years Flood of 1997. The flood occurred due to a powerful winter storm that crippled much of Western Nevada, most notably the Reno-Sparks area. The storm began on December 20 and lasted about three days. During that time, it dropped up-to two feet of snow in the region. At the time, it was described as the biggest winter storm of the decade.
Reno and Sparks weren't the only towns affected. Towns like Carson City, Minden, and Virginia City were also victims of this massive snow storm. At the storm's peak, around 16,000 homes were without power. The initial storm may have ended after three days, but the worst was yet to come.
All of that heavy snow eventually melted and was a humongous factor in causing one of the worst floods in our state's history. As the snow melted, the Truckee, Carson, Walker, and Susan rivers all began to overflow with rushing water. Additionally, a chain of rainstorms continued to hit the Reno-Sparks area, which only exacerbated the problem by melting the snow even faster.
It's estimated that the 1997 flood caused around $1 billion worth of damage. Runways at the Reno-Tahoe International Airport were entirely underwater, vast measures were taken to protect the city's casinos, and over 1,400 homes and businesses were damaged. Over 50 individuals were injured during the flood, and two were killed.
Eventually, the flood passed and the city began to recover. However, some valuable lessons were learned from this disastrous event. We won't be forgetting those lessons or the effect this flood had on our state anytime soon.
