1 Values going back through 2009 are shown since past mining may still be mpacting the South Platte River.
2 The exposed ground water surface area in July of 2009 was computed by taking the time weighted average of the exposed surface water area before and after mining began during this month. Surfaces areas
for November 2011 through January 2012 are monthly averages.
