7 flood. Local standard time, as filed.
Debris in streams caused water to back up and caused flooding in portions of eastern Sierra County. Several buildings experienced flooding, including the U.S. Forest Service office in Sierraville. California Highway 89 was closed across Sierra County from the Nevada County line to Calpine.
Interstate 80 was closed because of a large mudslide approximately 5 miles east of Truckee. The mudslide occurred at around 3 am on December 31st, blocking both directions on the Interstate. California Highway 89 was also closed due to a mudslide. Donner Creek caused flooding of some buildings in Truckee. This was the second largest flood of record on Donner Creek. California Highway 89 was closed across Nevada County from Truckee to the Sierra County line.
Extensive flooding was reported along the Susan River. Streets in Susanville and county roads were flooded. Flooding also occurred at a Union Pacific railroad trestle. Logs and other debris became lodged in the trestle and water was forced to flow around the trestle, flooding the area. Minor flooding was also reported on the Pit River near Bieber and Nubieber.
Localized flooding was reported in areas south of Lake Tahoe. Sierra Pacific Power Company reported that at least eight power poles were knocked down, most likely due to the saturated ground. Power lines were also downed when trees fell on them. Around 4,000 people were left without power south of Lake Tahoe. This was the all-time record flood on Trout Creek in South Lake Tahoe and Tahoe Valley, flooding U.S. Highway 50. General Creek flooded California Highway 89 at Sugar Pine Point State Park.
Localized flooding was reported across eastern Placer County, especially on Blackwood and Ward Creeks, and the Truckee River. Blackwood Creek rose to its second highest level in the last 45 years.
Mainly rural flooding was reported in Plumas County.
Localized flooding was reported on the East Fork Carson River near Markleeville, and in rural areas across the eastern half of the county.
