Fish Creek Borehole: The reservoir drop house area was saturated. It was not obvious where the <br />water leak is originating. The water is moving down the access road ditch and to the perimeter ditch <br />of the treatment ponds. Saturation ends in the ditch at a location adjacent to the second treatment <br />pond. If the quantity of water were to increase, the flow path could continue to the Fish Creek <br />discharge point. Please locate and repair this leak as soon as possible this fall prior to snow <br />accumulation and freezing that could exacerbate the issue. Division will follow up that this has been <br />completed at the next inspection. <br />Number of Partial Inspection this Fiscal Year: 3 <br />Number of Complete Inspections this Fiscal Year: 2 <br />Page 3 of 12 <br />
