Wikipedia’s Tahquamenon Falls entry says that the upper Tahquamenon Falls in Tahquamenon Falls State Park are more than 200 feet across with a drop of approximately 48 feet. In the spring, the falls can push as much as 50,000 gallons of water per second. That makes it the third most voluminous vertical waterfall east of the Mississippi, after Niagara Falls and Cohoes Falls in New York.
As you can see, they are impressive even during times of lower flow. I thought this shot did a great job of conveying the size of these magnificent falls and really hope you get a chance to see them!
