All impoundment <br />inspections were conducted by a qualified impoundment inspector.

No Name #2 identification sign needs to be replaced. <br />2. No Name #4 needs hole in riser repaired. <br />3. Oak #2 is full of sediment and needs to be cleaned. <br />4. Middle Flume #1 identification sign needs to be replaced. <br />5. Ute #1 upstream face needs minor grading work due to livestock. <br />6. Horse #1 identification sign needs to be replaced. <br />7.

The last column on the table provides an estimate of <br />the remaining capacity in each pond where remaining capacity is defined as the volume <br />remaining after considering the estimated amount of sediment noted during the inspections. It <br />should be noted that Oak #2 was observed to be at capacity for sediment; this pond was <br />cleaned on October 16tH and October 17tH.
