  1. Vaki Riverwatcher Monitoring at Daguerre Point Dam Ryan Greathouse Pacific States Marine Fisheries Commission

  2. The Vaki • Fish counting device • Developed for aquaculture in late 1980’s • Photographs, video, silhouettes • Gathers data: • Time • Size • Speed • Direction

  3. Advantages V. Traditional counting methods • Function all year long • Useful in turbid conditions No fish handling stress • Long term cost • Automated • Reduce human error

  4. Disadvantages • Up-front costs to purchase and install • Vulnerable to vandalism

  5. Background • Vaki units installed 2003 • Monitor: • Abundance • Temporal distributions • Population diversity and age from length data • Trends\relationships between temp and flow Daguerre Point Dam Vaki unit Dam

  6. Fishways North facility enclosure. North Ladder entrance South Ladder entrance Riverwatcher

  7. Layout PC Riverwatcher

  8. Flow Riverwatcher Unit LED light bars camera Main Tunnel Scanners

  9. Flow Camera scanners scanners LED lights

  10. Scanners • Infrared beams • Disruption of beam produces shadow • Scanners reject objects under 40 mm depth

  11. ID With Silhouette Onlyexample: Sac. sucker • 4 characteristics distinguish this species: 1. Ventrally flattened head 2. Prominent ventral fins 3. Blunt or rounded head 4. Sub-terminal mouth distinct

  12. Images O. mykiss Chinook Hardhead Sac. sucker Sac. pikeminnow

  14. Chinook Temporal Passage* *Minimum Passage

  15. Historical Operation

  16. O. Mykiss Monitoring Issues ? O. mykiss • Identification difficult • Inability to ID Adipose • Silhouette images non-distinct

  17. System Upgrades 2010 • Improved power reliability • Updated hardware • Addressed issues with flooding, temperature, and vandalism

  18. Power Upgrades 2010 2003

  19. 125 Watts Panels (3) • 24 volt system • 12 Volt Deep cycle Gel (5) • 1325 Amp/hour capability

  20. Hardware Upgrade Computer housing Live video USB port Power converter

  21. Buildings • Computer • Power Converters • Generator • Maintenance equip.

  22. Future • 24/7 monitoring • Image analysis: • Sex • Run • species • Improved ID • Turbid conditions
