It depends on what part of the river you are in, it varies from inches to about 4 feet except through the pond that is much deeper
Depending on the trip you take and recent rainfall, Sean is correct, the water for the most part shin to waist deep.
You go across a small lake, depending the length of the trip. That part is about 6 to 8 feet deep. Other than that it is about 1 to 3 feet deep.
Some places are deep but other then that you could walk
