OKC - Okanagan Channel at VDS-3Status: Active - Non-Operational
General Operational Period: Year Round
Start Date: 11/6/2009 12:00 AM
The OKC site is located in the Okanagan (Canadian spelling) Channel at 310th Avenue/Road 18 upstream from Osoyoos Lake. The river in this section is channelized and Vertical Drop Structures (n=17) are used to control the river gradient. The array is located approximately 130 ft downstream of VDS-3. The river at this location is approximately 80 ft wide, enabling nearly full coverage of the width with four 20-ft antennas. Detection of adult sockeye salmon (Oncorhynchus nerka) is the primary focus of the array. Water depth during the sockeye salmon migration ranges from 10 to 24 inches. Optimal read range of 12-mm TX1411SST PIT tags in pass-by orientation ranges between 18 and 20 inches resulting in high detection efficiency. Four new antennas were added to the site in a second array in March 2017.

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.

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.
Select a type to view the history of equipment installed at this site. A missing End Date implies the information about the equipment is current.

Cleared Debris and Milfoil on and around all upstream and downstream antennas.

Maintenance Check at OKC. Antenna 03 is currently down. Conducted visual inspection and could not find any obvious issues. Likely faulty antenna as it has zero current. Biomark will be manually logging into master controller and tune the antenna while the sockeye are moving through (only during regular work days & hours). This is a mitigation measure for the current season but will need to be removed and replaced or repaired in future. Also conducted a read range test with test tags. Read range was lower for upstream antennas 01-04. Antennas 01-04 have higher noise which may be affecting the reduced read range; this is likely due to the proximity to the upstream VDS and the vehicle bridge over the VDS.
|3/18/2021 10:00:00 AM||General||Inspected nodes 3 and 7, and associated cabling. Attempted to determine the cause of low current in antennas 3 and 7. Could not locate any obvious problems, will need attention in the future.|
|6/28/2019 11:25:13 AM||SiteDown||Site was down from approximately 6/20 at 08:26 PM to 6/28 at 10:07 AM due to power issues.|
|3/16/2017 12:00:00 AM||General||Installed four new 20' antennas and IS1001 readers upstream of the existing array. New antennas are A1-A4 and existing antennas were renamed to A5-A8.|
|10/26/2016 1:20:09 PM||General||A new modem was installed by Skyeler Folks and the site is now automatically uploading data again. I turned on site checking|
|9/21/2016 3:08:43 PM||General||Master Controller and IS-1001 firmware was updated from version 1.6.0 to 1.6.1|
|9/20/2016 8:21:38 AM||General||I changed the exciter voltage level on all antennas from 4 to 3.|
|7/11/2016 6:35:27 AM||General||Switcher batteries were swapped out on Saturday 7/9. I increased the input voltage level to 3 on Monday 7/11.|
|6/4/2016 7:00:00 AM||General||The input voltage at the site dropped below 18V on Saturday morning at about 07:45 am PST. This caused the readers to automatically go into standby. I put the readers back into scan mode on 6/6 at about 05:45 am. The input voltage is currently about 22V. One of the switcher batteries has possibly gone bad causing the input voltage to drop.|
|4/26/2016 4:34:00 PM||General||The Master Controller and reader firmware were upgraded to version 1.6.0. After the upgrade the Master Controller reverted back to it's default ID of 01 instead of the correct A0. This caused a couple of rejected files last night. I changed the ID back to the correct one and will manually repair the rejected files and re submit them.|
|9/15/2015 4:06:25 PM||General||Site file checking has been temporarily disabled.|
|9/15/2015 2:00:11 PM||General||On 8/25 and 8/26, the mux reader was replaced with a Master Controller and four IS-1001's.|
|9/15/2015 2:00:11 PM||General||A new cell modem was installed at OKC. I configured the modem and downloaded the MC buffer and uploaded the buffer to PTAGIS.|
|9/15/2015 2:00:11 PM||General||I reset the MC time, changed the noise alarm threshold to 50% and set the tag unique delay to 1 minute.|
|9/15/2015 1:57:30 PM||General||Site checking enabled on 9/15/2015 at 1300 hrs.|
|8/25/2015 9:00:00 AM||SiteDown||OKC site is down during reader upgrade since 8/25 a.m. We are replacing the mux with a Master Controller and IS1001 readers. Site checking is off until installation is complete.|
|6/1/2015 1:14:38 PM||General||Installed new CR1000 program ver 9.01 which eliminates the manufacturer tag prefix filter.|
|3/12/2015 8:26:45 PM||General||O&M visit on 3/12/15. I changed the lithium battery on the mux and re-tuned.|
|12/15/2014 12:00:27 PM||General||Tags with the 3DD prefix were not recorded before 10/22 because the datalogger had incorrect software that did not recognize tags with the 3DD prefix. The correct program was loaded on 11/19 and the mux buffer - which contained tags going back to 10/22 - was uploaded to PTAGIS on files OKC14295.ALL.|
|7/8/2014 6:36:26 AM||General||Site went down on 7/5 due to dead batteries. Possible power outage disabled the battery charger? Skyeler Folks replaced batteries on site on 7/7 and got the site back up and running.|
|2/3/2014 9:17:44 AM||General||Battery bank B was swapped out with new batteries on 1/31 at 1300 hours.|
