GARDNERVILLE, Nev. — Update 6 a.m., Monday — The main stem of the Carson River between Genoa and Carson City eased back from monitor stage Sunday evening as all points upstream continued to recede as well.

The National Weather Service has kept a flood advisory in place for Carson Valley as levels along the West Fork of the river remain high. Mottsville Lane between Highway 88 and Foothill Road — the main route from the Valley to Kingsbury Grade, remains closed.

Mostly sunny skies are in the forecast through the week with highs returning to the mid 70s after a cooler weekend.

The warmer temperatures will once again increase snowmelt and streams in the area will continue to run high with the highest flows occurring from the evening into the early morning hours.

Rain fell for nearly six hours over the Valley Saturday afternoon as the main stem rose into monitor stage, though points along the East and West forks of the river further upstream from the showed consisted drops throughout the day with significantly less snowmelt coming down from the mountains due to the overcast weather.

Aided by the rain, along with snowmelt carryover from earlier in the week, the river escaped its banks at multiple points around the Valley on Saturday.

The National Weather Service issued the flood advisory Saturday morning,  stating both the East and West Forks of the Carson River are running near or beyond channel capacity in Carson Valley.

Continued high flows due to snowmelt and saturated ground in combination with irrigation deliveries is causing the minor flooding along the river.


Minor flooding from snowmelt is expected to last into June. Any increase in snowmelt or rainfall may increase flows and lead to additional impacts.


No structures are currently threatened, but flood waters will impact sections of Centerville Lane, according to the flood advisory. Mottsville is closed due to water over the roadway.

Additional road closures remain possible.

Crews installed 600 feet of temporary barrier along the East Fork of the river by Aspen Mobile Home Park on Friday. Read more on that here.

Both the East Fork of the Carson River running parallel to Gardnerville and the West Fork of the Carson running through Woodfords briefly touched flood stage late Friday night before falling back over the following 24 hours.

The East Fork peaked just above flood stage, reaching 13.41 feet — just a shade over flood stage — around 11 p.m. Friday. It receded more than a foot over the remainder of the weekend according to U.S. Geological Survey readings.

Further upstream on the East Fork near Markleeville, the river peaked approximately three inches below flood stage Friday night and dropped roughly 18 inches through Saturday.

The West Fork in Woodfords touched just above the flood stage there of 14 feet, also around 11 p.m., Friday, before falling roughly 10 inches in the following hours.

The NWS reminds residents that rivers will be running high, fast, and are extremely cold in the coming days and weeks. The cold waters make hypothermia a distinct possibility for anyone in the water and the swiftness of the water can carry someone away rather quickly. In any areas where flows are high, even areas without warnings or advisories, bank erosion is possible. It is recommended to stay out of all water channels and keep any flood mitigation measures in place.
