This report discusses the flooding and resultant damages along the Truckee, Carson, and Walker Rivers and their tributaries in January 1997. The extent of flooding is shown in several full-color maps, and there are numerous color and black-and-white photos of these floods and the damages they caused.

The New Year 's floods in western Nevada and northern California resulted from several moderate to heavy snowstorms in the northern Sierra Nevada during December 1996, followed by three subtropical, heavy rainstorms from the Pacific, the last of which moved through the region from late December 30, 1996, to early January 2, 1997. This third subtropical storm was dubbed the "Pineapple" connection because of its origin in the Hawaiian region. It produced heavy rains at nearly all elevations in the Sierra Nevada, including the headwaters of the Truckee, Carson, and Walker Rivers. The warm heavy rains melted most of the snowpack in the Sierra Nevada below about 7,000 feet in elevation, and produced heavy rainfall up to 10,000 feet in the mountains, contributing heavily to the runoff. The runoff from rainfall at higher elevations, combined with the meltwater from the snowpack at lower elevations, caused one of the most damaging floods the region has experienced in the last 150 years.
