Often this information is available at no cost from State and Federal water resource agencies. The design of the dam must allow for the total natural and artificial runoff, so that when the area is abandoned the water can pass through or around the dam without soil erosion or undesirable impoundment occurring.

    A conventional impoundment is a surface retaining structure designed to store both tailings and mine water, with the aim of reclaiming the water for use in the processing plant as required. There are principally two types of surface impoundments, a water retention type dam, and a raised embankment that has many configurations (Vick 1990).
