This site is a permanent instream PIT tag detection system located at rkm 0.2 on North Fork Teanaway river near Cle Elum, WA. The site consists of two rows of antennas, with six 20-foot antennas installed in flat plate configuration. The two rows of antennas extend 15 ft beyond the wetted width of the channel during base flows. The antennas were built and installed by WDFW. The site is connected to solar power to charge the battery bank powering the transceiver. Site was decommissioned November 2015.

Event Log Summary

Event Date Event Type Comments
11/17/2015 7:00:00 PM General At around 7:00 PM, antennas 3-6 at NFT started to become disconnected or damaged due to excessive flows. Antennas 1 and 2 continued to run until 11-30 at 07:49 when the site was shut down.
2/3/2015 12:45:00 PM General The MUX was turned back on at 12:45 today. All antennas appear to be functioning properly.
12/9/2014 9:45:00 AM General At this time, NFT will be shut off for the winter months. The site will be turned back on in February before migrating fish are expected to move.
1/29/2014 11:23:17 AM General Antenna 6 was fixed at 14:45 on 1/28. A shed pit tag (3D9.1C2DEED18B) was wedged against the antenna coil creating higher than average noise. The array was powered down between 14:00 and 15:00 to allow us to locate the tag with a portable reader.
1/22/2014 7:56:56 AM General On 12-15-13 after 22:00, antenna 6 began to have increased noise levels. Presently, we are waiting for replacement antennas.
