April 17, 2012 C- 1981 - 014 /Southfield Mine KAG Initial attempts were thwarted by twisting of the water level cable. We then physically ensured that all twisting was eliminated by extending the cable horizontally across the ground surface prior to entering the well. We then slowly lowered the cable and probe into the well casing, detecting an audible and repeatable water level reading at 354 feet below the top of the casing. This reading could be related to the addition of water immediately prior to measurement. Additional measurements will be necessary over time to arrive at any �'- •" � conclusion regarding water level. It appears that the well is open to a significant void below the ground surface. Whether it is open to the mine workings cannot be affirmatively known at this time, although it is the Division position at this time that based on the previous fact that this well entered the mine workings and the our findings from this inspection that this well serves the purpose of detecting, measuring, and sampling water in the flooded Southfield mine workings. The Division has two recommendations: • Measure the well more frequently for the presence of water • Consider the use of a borehole camera to investigate the well casing for the entire depth of the well Mr. Patterson also asked me to accompany him to the site of the "Thompson culvert" located on Newlin Creek just west and slightly south of County Road 15. I accompanied Mr. Patterson to the site, where we found a 48 -inch diameter culvert under a ranch road that carried flow in Newlin Creek from west to east. The culvert was found carrying flow at a depth of about one inch at the outlet end (shown below) Number of Partial Inspection this Fiscal Year: 7 Number of Complete Inspections this Fiscal Year: 3 Page 4 of 6
