space equipment is used by Coors (Oxygen tester & man-hoist) when taking readings. Coors’ safety
policies do not allow the use of this equipment by state personnel to check the flume or for state
personnel to observe the Coors’ readings being made. Record is user-supplied information and is not
rated for accuracy. This record is requested by DWR Division 5 and the Upper Colorado River Commission
