SYC - Snyder Creek PIT Tag Array

Status:   Active - Operational
Site Type: Instream Remote Detection System  |  Organization: Yakama Nation
General Operational Period: Seasonally
Start Date: 1/1/2019 12:00 AM

The Snyder Creek PIT tag interrogation array is located in Snyder Creek, a tributary to the Klickitat River (RKM 22.8) (Klickitat County, Washington). The PIT tag array is located approximately 1.3 kilometers upstream from the confluence with the Klickitat River. The site consists of two 6.1 meter channel spanning arrays (one upstream and one downstream). The antennas are fixed to the substrate in a pass-over configuration. Two IS 1001 Antenna Control Nodes (ACN’s) in master/secondary master configuration, operate two antennas and record PIT tagged fish detected by the array. The site is powered by 6 12 volt batteries and has no charging infrastructure. Directions to the PIT array site from the mouth of the Klickitat at the Columbia River are as follows: Turn north onto HWY 142 from HWY 14. Proceed north on HWY 142 14 miles to an unmarked gravel road on the left side of the HWY just passed the 14 mile marker. From this point, proceed 0.2 miles to a gate. From this gate, proceed another 0.7 miles to another gate. From this gate, proceed 0.2 miles to arrive at the PIT array site.
