The number shown here is the distance, in inches, to Horseshoe Lake Corporation's "Red Flag" (No Wake) level. A positive number (any number above 0) means "No Wake". A negative number indicates inches below the red flag Level and there are no restrictions.


The maximum permitted speed of all watercrafts during a Red Flag event is 10 mph. Go even slower in the "No Wake" channel between the two lake sections.

You can change the time-frame by clicking on the aqua colored bar above the data.

Examples of how quickly the lake can go back down:


It was 16 inches high at 6am, July 1, 2021 and back to zero at 8:30am July 6, 2021, about 1/10th an inch per hour.

It was 33.67 inches high at 5:45pm, March 25, 2022 and declined to 5.5 inches by 10:40am, April 4th, 2022 (with a few sprinkles in between). Again, that's about 1/10th of an inch per hour.
