Interrogation Site Metadata

MVF - Moving Falls Fish Ladder

Status:   Active - Operational
Site Type: Adult Fishway  |  Organization: Confed. Tribes of the Warm Springs Reser.
General Operational Period: Year Round
Start Date: 7/29/2015 12:00 AM

The interrogation site is located in a fish ladder at a site known as Moving Falls on the West 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 upstream end of the ladder. At the upstream terminus of the ladder there is an adult trap. The trap is operated most of the year but is closed seasonally in the winter months. When the trap is not operated fish passage in the ladder is maintained except during extreme high water events. 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.
