All impoundment inspections <br /> were conducted by a qualified impoundment inspector. Inspections took place on August 27 and 28, <br /> September 3-5,10 and 24 of 2019. <br /> There were two maintenance items that need to be check/replaced: <br /> -Fill in/check animal burrows at Johnson#6. <br /> -Replace/check sediment marker at East Middle Flume#1. <br /> Data related to pond capacity is attached. The last column on the table provides an estimate of the <br /> remaining capacity in each pond where remaining capacity is defined as the volume remaining after <br /> considering the estimated amount of sediment noted during the inspections. <br /> The water level at Horse#1 was low enough that a new sediment marker was installed. This was done <br /> after its September 4, 2019 inspection. The sediment level is slightly below the new sediment marker. <br /> The sediment percentage is more at 55% versus the 60%that was recorded during earlier inspections. <br /> The water level at Deal#1 was low enough that a new sediment marker was installed. The was done <br /> after the September 5, 2019 inspection. The sediment level was below the new sediment marker. The <br /> sediment percentage is more at 40% versus the 55% that was recorded during earlier inspections. <br /> The new sediment percentages for Horse#1 and Deal#1 were recorded in the pond capacity <br /> spreadsheet. <br /> Please contact me if you have any questions. <br /> Sincerely, <br /> \\��,.o�¢Pp0•LICE�%;.;. <br /> ° 43864 C: <br /> onia Marie Perkins 9 � j�� <br /> CCE <br /> CO PE 43864 % �`• <br /> C:F.Luke/EQ file 118.7 ' IA'`1`G���\\`\ <br /> 00 <br /> P.O.
