Measurement Definitions
Recovery: Percent of channel depth available to deep water shipping. The recovery measure is focused on infrastructure and indicates whether or not the main ship channels in the storm affected area are open to the pre-Katrina depth. Restoration: Daily vessel arrivals. The restoration  measure is focused on shipping activity and indicates the number of daily vessel arrivals as a percentage the average number of daily vessel arrivals last year.
Amplifying Information
There are 19 deep draft channels in Mobile and 11 deep draft channels in New Orleans.  5 of the 30 total deep draft channels in the storm affected area are not at project depth although all 30 are open and at pre-storm depth.  The average number of daily vessel arrivals last year was 8.3 (250 mth/30) in Mobile and 12.5 (375/30) in New Orleans.  The number of vessel arrivals in Mobile and New Orleans varies little from month-to-month. The capability to operate at 100% does not mean the Channel is operating at 100% - for instance, The Channel could be at pre Katrina project depth, but lacks vessel traffic due to closure of facilities etc.  In this case, although they may not be moving the same level of cargo as before, they are still capable of doing so.
