ANT - Antoine Creek Instream Array

Status:   Active - Operational
Site Type: Instream Remote Detection System  |  Organization: Colville Confederated Tribes
General Operational Period: Year Round
Start Date: 1/1/2011 12:00 AM

Antoine Creek enters the Okanogan River at RKM 98.5, approximately 6 km upstream from the city of Tonasket, WA. Site ANT is located on Antoine Creek, 0.48 km upstream from the confluence with the Okanogan River. The site consists of 3 pass-through HDPE antennas accompanied by individual IS-1001 reader boards in series. Antenna sizes are as follows (upstream to downstream): Ant1 6 feet, Ant2 6 feet, Ant3 10 feet. The site is on grid power. Two banks of 12volt batteries in series create 24volts to run the MTS-MC unit. The batteries are connected to a timer switcher that will switch battery banks every four hours. The battery bank not running the MTS unit is then charged to capacity using a three-stage battery charger. A bioprobe collects and stores both air and water temperatures as well as the water depth data. The ANT site has a Cloudgate 4G cellular modem which transmits data to PTAGIS and Biologic.

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.

Node 2 lost current on 12/5 @ 0900. Manually tuned node and current came back on 12/6 @ 1100.

11/18/2019 10:30:00 AM SiteUp Replaced the damaged canbus and site is now operational.
11/16/2019 8:00:00 PM SiteDown Rodent chewed canbus cable between pods 2 and 3, shorted the MTS.
11/5/2019 10:00:00 AM SiteUp MC reinstalled and temporary antenna removed.
10/7/2019 10:30:00 AM SiteDown MC removed for emergency placement at a higher priority site. A single, temporary IS-1001 reader board and 10' antenna was placed at Antenna 3 location for data continuity.
8/26/2019 1:40:00 PM General Upgraded from a MUX to an IS-1001 MTS-MC and installed 3 new IS-1001 reader boards. Removed the 4 old PVC antennas, drove new T-posts and replaced with 3 new HDPE antennas in pass-through orientation. Swapped out old 12V batteries for new ones
