I am enclosing a copy of the lYthoTogy lay-ai -th: <br />borehole for your review. <br />The location of the pump in the windmill well is still in <br />question. When measured in February, the depth down the sucker rod <br />was approximately 42~. Since no information is known as to the <br />type and cu„tzguretion of the pumping mrctninism, it ie impossible <br />to determine where the bottom of the pump is located.

The only_tnue way to determine the <br />pump height and therefore the expected water elevation is to remove <br />the Dumping unit and take appropriate measurements.
