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 that W FC placed there to see if it would hold water. Other than that, no activity has <br />occurred that would have changed the sediment storage capacity from the final design volumetric <br />survey. My conclusion is that the sediment storage volume of Pond 008 and 009 have not <br />changed significantly and so I 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 week as I performed <br />my job duties and have only occasionally seen sediment laden water entering it from the pit <br />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 />Sincere) , <br />„^:~~ <br />Ross L.
