Spring Creek rating curve based upon 6 flow measurement periods in fall 2002 and <br />spring 2003. <br /> <br />. <br /> <br />Ground Water Levels: <br />Ground water levels at the three continuously monitored wells, 2, 3 and 4 had distinctly <br />different patterns of rise and fall (Figure 5). Well 2 dropped slightly, had a slight rise in spring <br />and slowly declined during the summer. Well 3 dropped shazply late in the fall and winter and <br />rose shazply in the spring and early summer. Water levels at wells 2 and 3 reached similar levels <br />in June 2003 as occurred in fall of 2002. Well 4 was broken by cattle in the late fall, and was not <br />discovered and repaired until late spring 2003. Water levels in this well remained near the soil <br />surface during the study period. The rise in Spring Creek stage in spring occurred during a <br />period when ground water level rose in all wells. <br />Manually read wells (Figure 6) indicate that a water level rise occurred through the site in <br />June and peaked in late June through early July. The largest ground water level change was <br />measured at wells 5 and lOon the northern side of the spring complex. <br /> <br />. <br /> <br />6 <br />
