There are bus services on the north and south end of the lake, but they aren't connected. There are only 55-thousand permanent residents, but Curtis Hasty of the Tahoe Transportation District says the problem is, tourism drives the total to 200,000 on an average day.

HASTY: "All of a sudden we are a small metropolitan area, two lane highways all trying to circumnavigate Tahoe, that's a big challenge."

It could get worse. Squaw and Heavenly resorts want to bring the X-games to Tahoe with tens of thousands of more people. So, they are teaming up for new transportation solutions. One is a ferry. 

HASTY: "We would be looking at two, they are just passenger ferries, they are not car ferries like San Francisco Bay, they are 120-passenger vesells, they are high speed , low wake can cruise 40-50 miles per hour so they would be year round."

He says the boats can carry the equivalent of 8 busses every hour. Public comment on the proposal is expected to begin in May.
