The capacity may be reduced where it is determined that periodic removal of the debris will be practical. In most cases, the basin should have a capacity to contain an estimated 10-year sediment yield from the watershed area. In no case should the capacity be less than a two-year yield. For cultivated land, the Universal Soil Loss Equation may be used in determining the soil loss. Use the following guidelines and Table 1 for determining the sediment yield from drainage areas of 100 acres or less.
Area is in permanent vegetative cover with minor gully erosion.
