minute. Inflows have decreased considerably since this time to 0.2 gallons per minute, <br />measured directly below the shaft, as reported in the 1994 annual hydrologic monitoring <br />report. Earlier measurements of inflow included inflow from mine workings adjacent to <br />the shaft as well as inflow from the shaft. Tate operator now measures inflows directly <br />beneath the shaft using a calibrated flume. <br />Year Intlow <br />1991 20 gpm <br />1992 15 gpm <br />1993 10 gpm <br />1994 0.2 gpm <br />Pumping of the Tatum Well <br />The Tatum well was pumped to get a rough estimate of its ma~amum capacity of the well <br />in its present poor condition A depth probe was placed at the bottom of the hole prior <br />to placing the pump in the well in order to avoid hanging up the probe on Ute pump <br />hose, wire and rope. <br />Aa electric pump owned by Ivlr. Tatum was lowered down into the well. This pump was <br />powered by a generator switched to 220 volts. Mr. Tatum stated that the pump would <br />produce up to 30 gallons per minute, The pump inlet was placed at about 10 feet from <br />the bottom of the welt, which corresponded to 10 feet above the previous intake of the <br />windmill pump. This level was chosen to avoid sucking in mud and debris and possibly <br />damaging the electric pump. At the time of the test, the water in the well was estimated <br />to be 1125 feet below the top of the casing or a little higher. The pump appazatus may <br />have displaced some of the water, thereby lowering the appazent water table in the well <br />when the pump string was pulled. <br />The pump was ntn until the well was dry. The pump was equipped with a checkvah+e <br />that would not allow water to flow back down the well. Water level recovery was <br />measured in 1(10 foot increments as follows: <br />
