Flow values from the 004 Pond have <br />been affected by the reduced diameter of the discharge culvert modified <br />on May 29, 1987 (36 inches to 6 inches). <br />Review of the TDS plot indicates that TDS values have consistently <br />increased since 1982, primarily due to a concurrent increase in <br />upgradient mined area and ground water resaturation in the spoils. <br />However, stabilizing of TDS values has occurred since 1997. <br />13 <br />
