Until the snow let up in the afternoon, chains were required on two major trans-Sierra highways linking the Sacramento, Calif., and Lake Tahoe areas: Interstate 80 over Donner Summit and U.S. 50 over Echo Summit.
But chains were still mandatory on Highway 88 over Carson Pass south of Tahoe, and a section of the highway near Kirkwood, Calif., was closed due to avalanche-control efforts.
Alpine Meadows spokeswoman Rachael Woods said the storm dumped from 17 to 24 inches of snow at her ski resort just north of Tahoe.
The nearby Boreal and Soda Springs resorts atop Donner Summit reported 13 to 18 inches of new snow.
"(It was) quite a spring storm," Woods said, adding such late-season storms aren't all that unusual in the Sierra.
The snowfall came as some Tahoe resorts are preparing to close for the season.
Water officials said they doubted the snowfall would help the Sierra overcome a dry January and end the season with an average snowpack water content.
