The Francis E. Walter Dam upstream can also affect the river's flow. The Lehigh River experiences seasonal trends with higher flows in the spring due to snowmelt and lower flows in the summer and fall. Interestingly, the river was once used for transportation of coal and lumber during the 1800s and was also a source of recreation for locals. Today, it is a popular spot for kayaking and fishing.
