Back in July, I wrote an email to UDOT about the ferry. Here is the response I received back:
I just wanted to reach out and thank you for your idea regarding ferry service at Lake Powell. Unfortunately the issue is not the size of the ferry in this case. There is plenty of water to float the ferry, there is just no way to get vehicles down to the current water elevation and load them onto the ferry. Extending loading ramps is extremely expensive, and we have not identified a funding source for it. Operating a ferry service at Lake Powell is extremely challenging even in the best of times due to its remote location. Furthermore, the severe drought conditions and low water elevation have made it infeasible without doing significant infrastructure improvements at the lake. We will continue to evaluate all options and appreciate your ideas.
