Audience:  Government and Public

A Logie 2100C resistivity counter was installed at the Kloiya River on November 30, 2005. 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 a vertical slot fishway. 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. 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 2.37C on December 18, and the highest mean daily water temperature was 11.55C on May 23. The counter was removed on May 26, 2006.
