in the spring
What do you mean? Like a flood? Or are you referring to the speed of the current? Yes. Rivers can flood but I hope that's not your question.
Rivers were usually high with the melting snow water and Spring rains. They had to leave in early spring to make it across the plains and to miss the fall mountain snows. It took at least 6 months to get to the west. Many lost everything in the flooded rivers. Even today these rivers still reach flood stage imagine being in a wagon trying to cross one.
