Pond 009, have been dry during each <br />visit so its sediment volumetric has not changed. Pond 008 has had a small amount of water in <br />the bottom from irrigation run off. Other than that, no activity has occurred that would have <br />changed the sediment storage capacity from the final design volumetric survey. My conclusion <br />is that the sediment storage volume of Pond 008 and 009 have not changed significantly and so I <br />elected not to survey for volumetric. <br />Pond 007 was surveyed for volume on March 10'" , 1999. At that time, it had approximately 10.4 <br />AC-FT of excess storage capacity. I have visited Pond 007 several times a quarter as I <br />performed my job duties and have only occasionally seen sediment laden water entering it from <br />the pit pumping system. The small delta at the entrance of the pit discharge point has not grown <br />significantly so I believe the storage volume of Pond 007 is still very adequate for any storm event, <br />Over land flow of irrigation water entering Pond 007 is clear because of the established vegetation <br />up gradient of the pond. <br />~~ <br />~ , <br />`- ' Ross L.
