Hydrologic Balance
Site Sedimentation Ponds 010, 011, O11A, 012, 013, and 014 were inspected. All site ponds
were retaining water. Ponds 010, 011, 12, and 013 were dischazging clear water. Pond inlets
and discharge structures are in good condition and functioning properly. Pond embankments are
well vegetated and stable. No problems were noted at any of the pond locations.
The lower Annand Draw drainage was inspected. The lower Annand Draw drainage appears to
have stabilized. The check dams placed across the drainage have functioned as intended by
controlling the erosion in the drainage channel. The check dams have all filled in with sediment
main, and until the Neck Pit Area is graded, topsoiied, and seeded (2002} it may be necessary to
clean the check dams at least one more time. Reseeding of the drainage channel bottom is also
recommended.
The YPM-12 drainage was inspected between Pond 011 A and Pond O1 I . This drainage channel
is also stabilizing and Looks to be in relatively good condition since the last repairs were made to
check dams and additional riprap added to the spillway below Pond 01 lA in 200. All check
dams were intact and functioning as intended. The mid-section of the channel showed some
erosion in areas where the channe( was backfilled. Please continue to monitor this location and
make repairs necessary to prevent erosion and to ensure the mid-section of the channel remains
stable.
