 Please feel free to login (first time will create account) and edit your section. I have put a few placeholders to show how this might work. Immediate needs refers to jobs you would like done by the mine crew as soon as there is any access. I have already communicated the need for SOLO, Gopher, and CoGeNT to keep radon plateout to a minimum.

-No one underground today. Power in the lab is minimal until power feed repaired.  Nitrogen purges are going on all experiments and will last through next week without intervention.  About half the single mode fiber was damaged, so fiber optic and network work is primary effort over next week.
+Full Power was restored to the lab over the weekend.  Cleaning crews and fiber optic cable splicing will occur through this week.  Computers will become available for remote access by the end of the week.  Currently expecting access may be as soon as mid-May, but we need to properly schedule visits, so we will being communicating directly with the experiments about their visits near the end of April.

-Whenever possible, I would like to bring the meter that is supported by foam back to my home.  If I am allowed to bring the instrument to the surface then I can come any time.  If someone else does this then the meter should be clamped first and I can meet them at the surface.

+• Full electrical power was restored to the entire Soudan Laboratory TODAY.
+DNR staff and an outside electrical contractor installed a new power cable
+between the 22nd and 27th levels. Lab staff then checked to be sure that
+all circuits in the lab were shut off. Following this check, power was turned
+on to the Lab substation via the new cable. Lab staff then turned on the lights
+and HVAC system in the Lab. These systems appear to function normally.
+The Lab closed loop cooling system also seems to function normally.
+The Lab fire detection system is also functioning and will shut down power
+to the lab, in the event of an alarm detection.
-Work at Soudan continued today in both the shaft and the lab.
+• The fiber optic cable has sufficient slack that it will be possible to cut out
+the damaged section and re-splice the cable. The splicing contractor will
+be working next week.
-• Dan Bauer and Jim Beaty completed work today to stabilize the CDMS Detector.
+• Representatives of cleaning companies will visit the lab on Monday to
+prepare estimates for general clean up of the lab, including remnants
+of the foam and the debris brought in by the foam.
