A sluice box should be set with a 4-8 degree angle. Another rule of thumb is that the sluice should be angled to drop roughly 2 inches per foot of length. The exact angle depends on the size and weight of the material, the riffle design, and the speed of the current. As you see, there is not a universally applicable answer as to what angle is ...
