It took many visitors up to an hour to get through the gates of Shoshone Falls today.
In fact today they saw more than a thousand cars.
Officials say Shoshone Falls was supposed to be running at 17,000 cubic feet per second - more than double of what it was earlier in the week.
And the city is prepared for the possibility of increased traffic.
They will continue to run buses to and from Dierkes Lake to the main overlook point for Shoshone Falls on Sunday.
Dennis Bowyer says, “Back in 2006, we had a lot of crowds. We had over 2000 cars a day and of course we don't have the parking for 2000 cars so we have to be prepared.”
The bus service will run from nine a.m. to six p.m. running at 15 minute intervals.
They tell everyone to be prepared as there could be possible delays.
