A strong atmospheric river brought heavy rain with widespread flooding on the 8th and 9th. There was a period of snow on the 7th, as well as freezing rain in some lower valleys into the morning of the 8th.  Pre-emptive planning caused the closure of public schools and courts in Washoe County on the 9th. Many roads were closed due to flooding, overwhelmed and blocked culverts, and debris flows in the Reno-Sparks, Carson City, and Minden areas on the 8th. A damage estimate from Washoe County Emergency Management for the entire county in January was over $15M, with much of the damage between the 7th and 9th. In Storey County, a damage estimate from flooding and snow in January was $6M for public infrastructure.

Twenty five structures, including at least 10 homes (one 8-plex and two single-family homes), were damaged by flood waters in Dayton by the morning of the 9th. Flooding of the two single family homes in East Dayton may have been largely due to breaks in ditches and culverts incapable of handling the exceptionally large volume of water. Water depth varied from 6 inches to as much as 3 feet on the south side of the Carson River. Standing flood waters lasted for at least several days after the initial flood surge on the 8th. Schools were closed county-wide on the 9th. The damage estimate from the Lyon County Emergency Manager is considered very low-end and could actually be several million dollars for Dayton alone.  In February, a Federal Disaster Declaration was approved for the January flooding.

Flooding from Steamboat Creek and the North Truckee Drain (near I-80 in Sparks) combined with some input from the Truckee River to bring a large area of lowland flooding between McCarran Blvd and Hidden Valley, as well as south of Interstate 80 in the Sparks Industrial area. Several days of notice allowed many businesses and homes in Hidden Valley (near Boynton Slough) to prepare flood mitigation measures including sandbagging. However, several homes in Hidden Valley still had flood damage due to overtopped sandbags and/or basement flooding.  The timing of the flood is approximate and the damage is roughly estimated.
