The U.S. Forest Service and California Tahoe Conservancy still need to sign-off on the merger.
But if it goes through, guests will be able to access more than 6,000 acres of skiing, a feature that could potentially impress Winter Olympics officials scouting future sites.
Julie Maurer is with Squaw Valley:
"I don't think it would hurt with it at all just in terms of the combined resource - that definitely could be a plus."
But Carl Young with the League to Save Lake Tahoe says they're worried about the merger and how hosting the Olympics could affect the lake's fragile ecosystem.
"With all that would be built in terms of infrastructure, if not done properly, the impacts to the Lake could be substantial and in some cases perhaps permanent."
Federal and state officials are expected to make a decision on the merger in 45-days.
