Our family just returned from our first trip to Gooseberry Falls State Park just north of Two Harbors, Minnesota. This was an informal scenario. Below is the only time lapse I set up during the trip (since the family was the focus and I didn't want my 3 and 4 year olds to take a swim by accident), however... it looks like it's worth another trip back.
We learned that the falls this year have been flowing extremely fast due to the amount of rainfall the area has had.
Let me tell you, this water was GUSHING. I just googled some images of the falls during what I assume to be a typical time of the summer, and it is a night and day difference. That being said, we found plenty of evidence of even higher river levels that would have made it impossible to walk some of the trails.
While there, we learned that the falls this year have been flowing extremely fast due to the amount of rainfall the area has had. They weren't joking. Let me tell you, this water was RUSHING.

Normally to get this sort of ribbonlike or streamy kind of look to the water in daytime photos you have to add some heavy darkening filters to let your exposure to be slow enough to create this effect. This was only with a graduated filter on ISO 100 at about 1:30 in the afternoon (which is NOT the best time to work).
