  1. Watercraft Inspection/Decontamination for Aquatic Invasive Species Glenn Dolphin Oregon State Marine Board

  2. Presentation Outline • 100th Meridian Initiative • Zebra/Quagga mussel rapid response plan • Level I vs. Level II trainings • Types of boat contamination • Boat inspection techniques • Boat decontamination • Boat intercepted in Oregon • Boat ramp pilot project • Summer 2009 OSMB outreach effort

  3. Columbia River Basin Planning Early Detection and Rapid Response Interagency Planning and Response to a Mussel Invasion • 100th Meridian Initiative – CRB Team • Approximately 20 State & Federal agencies represented • Hold quarterly meetings Have written: • CRB interagency invasive species response plan for mussels • Economic evaluation of impacts for CRB hydropower facilities • Have practiced using the response plan during a “table top” exercise

  4. Watercraft Inspection Trainings • Level I • AIS awareness, boat inspection techniques • Level II • Hands on use of decontamination equipment on live mussels at an infested water body • First Level II course (Lake Mead Academy) held from April 8-9 2008 • Five Level II trainings were held in 2008 with 50 participants • Upcoming level II March 3-4 and April 7-8 2009 (full)

  5. Statewide Training Watercraft Inspection Training (WIT) (2007 + 2008) • LEO – OSP +County Marine Patrol • State/Federal agency field personnel • USCG auxiliary • ODOT ports of entry

  6. Types of Boat Contamination Boats with: • Aquatic weeds • Mud snails • Live bait • Attached mussels • Standing water in boat

  7. Boat Inspection Outdrives Lower Unit Props + prop shaft Trim tabs Bilge drain plug

  8. Boat Inspection Trailer rollers Boat hull

  9. Boat Inspection Boat hull Trailer bunk

  10. Boat Inspection Pitot tubes – measure speed Transducers – measure depth

  11. Boat Inspection Trim tabs Water intake screens/filters

  12. Boat Inspection Live wells/bait wells Anchor/rope lockers

  13. Boat Inspection • Sailboats have unique features like • Centerboards or keels • Centerboard boxes • Rudders

  14. Watercraft Decontamination

  15. Decontamination tools

  16. Boat Decontamination Gimbal area + motor mount

  17. Boat Decontamination Engine cooling intake Through hull fittings

  18. Mussel Infestation • Responses by other Western States. • Restricted access to infected waterways • Closure of water bodies to boating access (CA) • Mandatory boat inspections at State borders • Boat inspections at local boat ramps • Mandatory boat decontamination upon leaving infected waters • Management plans for infested waterbodies (UT)

  19. Contaminated Boat

  20. Boat Decontamination

  21. Boat Decontamination Approx. 50 mussels

  22. Boat Decontamination

  23. Lessons Learned • More public outreach needed to inform boaters! • We need your help to be on the lookout! • Oregon needs to establish boat decontamination sites around the state with adequate equipment. • Oregon needs adequate laws to protect the state, similar to Washington’s laws. Currently OSMB, ODFW & OSP staff are working diligently on solutions!

  24. East Lake Boat Ramp Pilot Project • Targeted outreach to boaters • Occurred between August 26th – Sept. 12th 2008 • Try to encourage boaters to adopt “clean boating” practices. • Customized printed material for local conditions. • Received rack card upon checking in at entry booth. • Asked to perform vessel inspection, fill out an inspection checklist and complete survey. • Silent observation surveys by USFS staff to document boater behaviors (before/after).

  25. East Lake Boat Ramp Pilot Project

  26. East Lake Boat Ramp Pilot Project • Returned rack card results: • 46 cards returned to drop box • 78% were aware of AIS prior to receiving material at East Lake. • 56% indicated they performed a boat inspection for AIS as a regular activity. • Observation results: • 50% of boaters with observed weeds on their boat inspected and cleaned them off. • This percentage was the same for both pre and post signage and rack card distribution. • However, very small number set (4-pre/16-post).
