Operational History

Operational history describes the period the site was interrogating for PIT tags. The comments provide anecdotal information about the operation of the site during this period. Site operational periods are updated typically at the end of the calendar year.

Year Start Date End Date Comments
2005 1/1/2005 12:00 AM 4/8/2005 9:00 AM The Ice Harbor South Shore adult ladder was dewatered for annual maintenance between January 3-27, 2005. The North Shore ladder was dewatered for annual maintenance on January 31, 2005. All transceivers on the north ladder except for 0C were mistakenly put into standby on 3/3/05 at 9:15 am. This was found and corrected on March 7. The IHA site definition was transferred to the new IHR composite site on April 8, 2005. This is the last (partial) year of operation under the IHA site code.

2003 3/11/2003 3:00 PM 1/1/2004 12:00 AM This the first year of PIT tag detection in the Ice Harbor Dam ladders. Detection began in the left (South) ladder at 3:00pm on March 11, and in the right (North) ladder at noon on March 12. Interrogation data was buffered in the transceivers until 3:45 pm on March 19, when the data collection platforms went live, and date/time stamps were first associated with each detection. The buffered data from prior to 3/19, and any duplicate interrogations recorded subsequently, were offloaded on March 21 into two data files, IHA03080.F and IHA03080.H. Interrogation activity in the left (South) ladder was interrupted between 3/20/03 1:40pm and 3/21/03 11:00am due to an electrical hazard.


Configuration metadata includes details about the equipment used at the site to detect and record PIT tags. A new configuration sequence record is created when equipment is added or removed from the site and the period of time it was active. A configuration sequence without an End Date is currently active.
