Findings:
a. The abutments were not inspected.
b. Satisfactory – Expected to fulfill intended function – no corrective action required.
c. Fair - Expected to fulfill intended function, but maintenance or other actions are recommended.
d. Poor – May not fulfill intended function; maintenance, repairs, or other actions are necessary.
e. Unsatisfactory – Is not expected to fulfill intended function; repair, replacement, or modification is necessary.
f. Unknown – Not visible, not accessible, not inspected, or unable to determine based on the observation taken.
Corrective Actions:
g. Slope protection needs maintenance or repair. Description:
h. Rut and/or Gully erosion was observed, which requires maintenance and/or repair.
Description:
i. A crack was observed along the abutments, which requires further investigation to determine the underlining
cause. Monitor the area and/or repair as required.
j. The abutment area was not visible due to high grass and bush vegetation. Clear high vegetation and maintain
low to enable easy visual inspection.
k. Tree(s) were observed on the dam embankment. Trees have been identified as the probable cause of piping
failures, and can possibly cause severe damage to the embankment if they are uprooted during a high winds.
Corrective action is required to remove the tree hazards from the dam. All repair work shall be accomplished
as per the requirements of licensed geotechnical or civil engineer. Routinely monitor the damaged area for
signs of settlement and seepage.
l. Seepage/Ponding water was observed. Monitor and conduct further investigation to locate the source of water
and extent of any possible hazardous or developing condition.
m. Seepage was observed flowing and particles were observed to be removed by the flow. Take immediate
action to stop the loss of soil from the embankment. Conduct further investigation to determine the underlining
cause and take corrective action. Monitor the area.
