RESULTS -SPRINGS FOR WATER YEAR 2003 <br />Three springs were sampled during the 2004 water year. Spring 1 (Upper Carbon <br />Junction Canyon) above the mine was dry during inspections of October 7 and December <br />18, 2003. During March 2004 the spring was flowing and sampling took place. The <br />spring was again dry during the June 2004 inspection. As described above, this spring has <br />been dry for two decades and began to flow during the spring of 2003. Flow took place <br />again this water yeaz, and it is likely flow has returned as a result of normal levels of <br />winter precipitation in the area. Spring 3 (REA SPG #3) was flowing during March and <br />June 2004 sampling events, while Spring 4 (CJ-LO-SPG #4) was flowing only during the <br />March 23, 2004 sampling. Springs 3 and 4 originate below the mine and permit azea. <br />Spring 3 (REA SPG #3) is approximately 1,000 feet south of the permit azea in REA <br />Canyon. Spring 4 (CJ-LO-SPG #4) is approximately 200 feet west of the permit area in <br />Carbon Junction Canyon. Summaries of the data collected for the 2004 water yeaz for the <br />springs aze found in Tables 1 through 3. <br />Spring Flow Rate <br />Flow rates at springs 1, 3, and 4 appear to respond to seasonal rechazge, snowpack, and <br />recent precipitation events. In general, spring flow is highest during the spring months of <br />the calendar year, responding to infiltration from snowpack and shallow groundwater <br />rechazge. Spring flow is usually lowest during the autumn and winter of the calendar year, <br />reflecting drier conditions with less precipitation and recharge to the springs. During <br />yeazs with high snow pack, such as 1994-1995, flow rates were significantly higher than in <br />more normal years (1997-1998) or dry yeazs (1998-1999). Flow rate information was not <br />collected for the 2004 water yeaz at the springs. <br />Spring Temperature <br />Temperatures of spring flow also appear seasonally related. During the winter and eazly <br />spring, temperatures aze at their lowest. With the onset of warmer weather, spring <br />temperatures rise through the summer. With the coming of autumn and winter, spring <br />temperatures begin to decrease and reacfi their lowest level during first calendaz quarter <br />sampling, This phenomenon appears to support the conjecture that these springs aze <br />shallow and rechazged largely by winter snowmelt. Spring temperatures during this water <br />yeaz were within the range of previously recorded temperatures. The temperature for <br />Spring 1 was relatively warm compared with the other two springs the past two water <br />years, though within the range of historic temperatures recorded for Springs 3 and 4. The <br />water temperature for Spring 3 was within the historic range and reflected the seasonal <br />fluctuations descnibed above. The temperature of Spring 4 remained more consistent with <br />temperatures from the majority of the last ten water yeazs. <br />L <br />Carbon JuncWn Mine Paga 4 <br />Annual Hydrologla Reportfor Water Year?AO4 <br />
