Pond 1 is located at the <br />top of the series and pond 4 at the bottom. During this thunderstorm, three of these <br />ponds, ponds 2 ,3 and 4 all discharged from their emergency spillway's. It should be <br />noted that Ponds 2 and 3 primary spillways valves were open but due to the magnitude of <br />the inflow, were incapable of releasing enough water and, as a result, the inflow went <br />over the emergency spillways. <br />At the time of this storm, these pond were incompliance with the State of <br />Colorado, Department of Reclamation, Mining and Safety (DRMS) requirements. The <br />ponds are inspected quarterly by both a DRMS official and Bowie and were last <br />inspected by a DRMS official on June 22, 2010 and found to be compliance. At the time <br />of the thunderstorm, ponds 1 through 4 were dry and sediment loads were below the <br />required clean out levels therefore, ponds 1 through 4 had the required storage capacity to <br />control a 10 year, 24-hour event.
