First we'll talk about the inside and outside curves. As a river flows, the current cuts deep banks, which are called outside curves. It deposits gravel, sand and debris on the inside curves. Outside curves mostly consist of deep water, fallen trees, root systems and bigger rocks. Inside curves consist of sandbars, smaller pea gravel and shallow water flats.
Current breaks can be any type of object that provides a substantial reduction in water flow.
This can be a man-made bridge, a tree lodged in sand in the middle of a river, log jam, large boulders, or any type of fallen trees along the bank. One thing you have to remember is that fast-moving rivers are harder for bass to live in. Medium or slow-moving rivers are best. This might be a hole 10 feet deep and 30 yards long on larger rivers. It can also be 20 feet deep and run for a quarter of a mile or more.
