Colorado Springs, Colo. - The special water committee appointed to arrange some plan of unwaterlng the Cripple Creek district is reported to have adopted a plan known as the El Paso tunnel, and estimated to cost between $80,000 and $100,000.
  Sherwood Aldrich is Chmn. of Com.

  The regular monthly report on the progress of the tunnel being driven by the El Paso Gold Mining Company for the purpose of draining the mines of the western portion of the camp, will be received this week by the company.
  The progress during March is said to have been greater than at any time since the tunnel was started. The El Paso people expect to have the tunnel completed several days ahead of the schedule unless some unforseen accident occurs to delay the work.
  The contract calls for the completion of the work by August 28th.

  Official announcement has just been made by Superintendent Bainbridge, of the drainage tunnel, that the bore will be completed between August 30 and September 1 next.
  This announcement is very gratifying to mine owners whose property will be tapped by this tunnel.

  Water will be running through the Cripple Creek drainage tunnel within the next two or three days. The last shots necessary to penetrate the last strata of rock were placed Sept. 2.
  All that now remains to be done is to remove the track from the floor of the tunnel and shoot away the bulkheads which have kept the water in check.
  This will be done immediately and a large number of the mines which have been flooded will be relieved. The tunnel is 4,074 feet long and was begun January 25 last.
  Its completion is believed to mark a more productive epoch in the history of the Cripple Creek district.

  The most important event in Cripple Creek district, mining circles during the past week was the completion and opening of the El Paso drainage tunnel, which is now draining the mines in the western section of the camp to a depth of 250 feet below the present water level.
  When the valves in the bulkheads which held the water in check, were opened, water to the extent of 4,000 gallons per minute flowed from the mouth of the tunnel.
  The tunnel was commenced January last, and it has taken eight months of unceasing work to complete it, to say nothing of the immense amount of money expended.
  It will relieve immediately some ot the heavy producers of the camp.

  Water is steadily subsiding in the several properties of the Cripple Creek district where it was early assumed that effects would first be felt.
  Reports of substantial gains continue to come from the Elkton and Mary McKinney mines, the chief indicators at this time of the falling level. Up to last Sunday there had been a fall of about one foot for the week at the Elkton, which is the general average each week for this property. At the Mary McKinney the fall recorded was ten inches for the week.
  This makes the total fall at this time about five feet, while at the Elkton it is approximately four feet. The bottom levels of the El Paso and C. K. & N. mines are dry.

  The beneficial effects of the drainage tunnel are being felt in every mine in the Cripple Creek district previously hampered by water.
  • The El Paso, the first mine to reap the benefit from its direct connection with the big bore, is dry and sinking will resume shortly.
  • The same may be said of the C. K. & N. and other Beacon hill properties.
  • Farther to the north, in the Elkton, Mary McKinney and as far away as the El Paso Gold King in Poverty Gulch, the water has fallen at the rate of from four to five feet per month.
  • In the Ajax, Gold Coin and other Battle mountain properties the water level is gradually falling.

  With the El Paso, C. K. & N., Old Gold, Henry Adney and Little Bessie properties hoisting ore again, the west slope of Beacon Hill shows considerable more activity than it has for sometime past.
  Since the completion of the drainage tunnel, properties on this hill have taken a new lease on life. Six cars of ore are being loaded from this side of the hill, most of it of smelting grade.

  A large number of mining properties in the Cripple Creek district are feeling the result of the opening of the drainage tunnel by a very noticeable decrease in their water lines.
  • The water in the Elkton and Mary McKinney properties is receding at the rate of five feet per month.
  • The water level in the American Eagle and Ajax properties on Battle mountain is also being lowered at about the same rate.
  Nearly every property in the western section of the camp is feeling the beneficial effect of the drainage tunnel, while the mines on Beacon hill have been drained entirely.

  The water flow from the Cripple Creek drainage tunnel has been doubled within the last few days and is running from the portal in a volume of 1200 gallons per minute greater than at any time in its history.
  While advancing the east heading last week, a channel was cut that contributed 500 gallons per minute. Successive advancement added more of the element and the other day a round of shots allowed another flow to escape.
  The last stream brings the total flow from this heading up to 1500 gallons, and the total flow from the portal up to 3000 gallons per minute.
  The development of this last flow completes the contract of the El Paso company but not of the tunnel company, which will continue to bore as long as conditions warrant.

  Another measurement of the flow of water from the El Paso drainage tunnel made last week confirms an early statement of Engineer Jasquith that 5,000 gallons a minute was pouring from the portal.
  The flow is something enormous and all the mines in the north end are being unwatered at a rapid rate. The Mary McKinny and Elkton will shortly be able to work in their lower levels.
  The increased flow was caused by the driving of the east lateral toward the Elkton property. So rapidly did the water pour through this lateral that the men found it impossible to work.
  There is being discharged at the present time approximately 300,000 gallons per hour, or the enormous total of 7,200,000 gallons every 24 hours.

  At the present time considerable talk is being indulged in by mine owners regarding the extension of the El Paso drainage tunnel. The tunnel is now in about 6,500 feet and is discharging water at the rate of 6,500 gallons per minute.
  It will perhaps be necessary to vary the course and drive it fully  another mile before it will have the desired effect on the mines of Bull hill, which is its objective point.
  Should the tunnel be continued in this direction, the Findley, Golden Cycle, Hull City Placer, Last Dollar and many other mines would be drained to a depth of 1800 feet.
  All the above named properties are dividend payers.

  Many mines in the north end have already been unwatered, and nearly all that were affected at a depth of 600 feet have been unwatered by the tunnel.

  On Jan. 1, 1908, the flow from the El Paso tunnel approximated 2,000 gal. per min. Since that time the flow has gradually subsided until at the present it amounts to barely 800 gal. per min.
  According to this fact it is calculated that within a few months the water flow will be very small.
