The San Francisco Chronicle reports that it's unclear whether the tech giant will continue the ferry service for its employees.
Google began a month-long trial run of ferry service from San Francisco's Ferry Building to Redwood City last month.
Last week, the company added a five day test run from Alameda's Harbor Bay.
The trial runs ended on Friday.
A port official says if Google does decide to put ferries back on the bay, it probably won't happen until summer
In recent months, Google has been at the center of a San Francisco controversy over private buses that several large tech companies use to transport workers to Silicon Valley. Some community members say the buses are congesting city bus stops, so the city recently voted to charge the companies for each stop the buses make.
