A Logie 2100C resistivity counter was installed at the Kloiya River on January 19, 2007. The counter electrodes are located within a plastic tube 150 cm in length with a inside diameter of 37.5 cm. The tube was placed near the top of the vertical slot fishway. A Capture Digital Video Recorder, in combination with a 37CHR-IR Nightview underwater camera, was used to confirm species identification. Steelhead migrating through the fishway passed through the culvert resulting in a change in conductivity that was analysed by an algorithm and recorded by the counter. The DVR was triggered by the counter to record a digital image five seconds before and five seconds after a change in conductivity was detected by the counter. A row of data for each event was comprised of the date, time, direction of travel and peak signal strength. Trace data was collected on a Toshiba laptop computer. Electrical power was provided by a gasoline powered Honda generator for the duration of the project. Hourly water and air temperatures were collected on Optic Stowaway temperature data loggers during the project. The lowest mean daily water temperature recorded was 1.48̊C on January 19, 20 and 21 respectively. The highest mean daily water temperature was 8.28̊C on May 13.
