All impoundment inspections <br />were conducted by a qualified impoundment inspector. Inspections took place on September 11, 2018. <br />There were four maintenance items that need to be check/replaced: <br />- Sediment Marker at West Pyeatt #1 needs to be replaced. <br />- Identification sign for Middle Flume #3 needs to be installed. <br />- The spillway at Middle Flume #3 is incomplete and requires additional work. <br />- There is erosion around the weir at Middle Flume #3 that requires repair. <br />Trapper will address these maintenance items in a timely matter. <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 />Please contact me if you have any questions. <br />Sincerely, \\\\\\ PQ0 LlgF <br />, •••RIE•'•?cI'�� <br />i to 43864 <br />.CCE <br />01)L zz�-o:-13-1$ Q <br />Tonga Marie Perkins ��•. : ���.� <br />CO PE 43864%,����i/S'/p'NIA�`\f`�\\\`o\\. <br />C: F.
