August 1994 ES-ii 933-2713.003 <br /> Conjunctive flow characterization involves determining the volume of surface water passing a <br /> given point during a specified period of time, as well as determining the concurrent volume of <br /> groundwater within the creek sediments passing the same point. Surface water flows in Cement <br /> Creek have previously been measured, both at high flow and at low flow. The water level data <br /> obtained from the piezometers were combined with the hydraulic conductivity data to estimate <br /> the volume of groundwater which is expected to migrate through the sandy gravel. Results <br /> indicate that groundwater flow is at most approximately 0.4% of the total conjunctive flow, and <br /> therefore does not significantly affect the volume of conjunctive flow. Accordingly, monitoring <br /> of surface water flow is Cement Creek is sufficient to determine the effects of adit plugging on <br /> the total flow in the creek and no further groundwater monitoring is recommneded. <br /> Golder Associates <br />
