If the water were ankle deep the bottoms of the pants would be wet. I expect the water was a bit deeper. One thing everyone has to keep in mind is that the flow and the levels of the creek change. So, when you get to see the JM videos which were taken weeks later the water flow and levels were much lower than they were on the 13th.
Here is a 5 day view of the creek data from February 10th, 2017 through February 15th, 2017.
And here is a 38 day view of the creek data from February 10th, 2017 through March 20th, 2017.
You can see that both the depth and the flow of the creek have been significantly lower since the 12th of February (the peak you see) and also the 13th of February where the levels were only beginning to come down.
For reference, the gage that does the measurements is located upstream of the Monon High Bridge at the bridge for 300N.
