Along Water Canyon on the way to Mossy Cave is the Mossy Cave Waterfall, also called the Tropic Ditch Falls. The water drops about 15 feet (5m) over a ledge into a shallow circular pool. While the waterfall itself is not that spectacular, what makes it so picturesque is that it’s surrounded by the famous hoodoos of Bryce Canyon National Park.
Water Canyon is not a natural river, but an irrigation ditch that was built by Mormon settlers between 1890 and 1892 to supply water from the East Fork of the Sevier River to Cannonville and Tropic in the dry season (when the Paria River stops flowing). This section of Water Canyon was not dug by hand, but uses what would have been a dry wash to channel the water.
