Lower Mulberry Fork of the Black Warrior River Professional Review and Guide
"Mulberry Fork is a typical river for the region. That said, it has individual characteristics. As always, for all rivers in this region, the water’s level plays an important role in how the river will affect your run. The rating of II+ means that at very high water levels, some of the rapids turn into Class III. The run is capped at the end by the infamous “Hawaii Five-O” wave at the takeout.
This section from the old US 31 bridge is usually called the Lower Mulberry, because there are two other sections of the river above this point (sometimes known as the Upper Mulberry and the Upper Upper Mulberry), which also provide excellent runs. The Lower Mulberry would be classified somewhere between the Upper Upper, which is a mellower ride with lots of pools and eddies, and the Upper, which offers a somewhat wilder ride. Mulberry Fork is the dividing line between Cullman and Blount Counties."
