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
watercraft inspection trainings
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)

mussel infestation
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)

lessons learned
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!

east lake boat ramp pilot project
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).

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).
