Site Type: Adult Fishway  |  Organization: Confed. Tribes of the Warm Springs Reser.
General Operational Period: Year Round
Start Date: 3/9/2016 12:00 AM

The interrogation site is located in a fish ladder at a irrigation diversion site for the East Fork Irrigation District on the East Fork of the Hood River. The ladder is a vertical slot type construction. Two antennas are installed in a pass through configuration at two of the vertical slots at the downstream end of the ladder. At the upstream terminus of the ladder there is an adult trap that is intermittently operated. The fish ladder and interrogation site is operated seasonally cooresponding to the irrigation season (March to October). The antennas are controlled by two synced Biomark IS1001 ACN readers. Power is provided by solar panel(s) charging a deep cycle battery bank. Interrogation data is manually downloaded periodically.
