  2. Overview • Asian carp • Chicago Area Drainage • Range and spread of carp • Asian Carp and Dispersal Barrier Background • Draft Framework Approach • Draft Framework Short-term Actions • Draft Framework Long-term Actions • Funding • Comments

  3. Why we’re worried • Large bodied (>100 lbs) • Bighead: 5 feet, 90 pounds • Silver: 3 feet, 60 pounds • Eating machines • Up to 20% of body weight/day • Planktivores • Eat same food as natives • Reproduce, develop quickly • 1 female = 1- 500 million eggs • Grow to ~10” in year 1 • Tend to jump when startled

  4. Saint Louis

  5. Range and Spread • Can adapt to northern temperate zones • Currently within striking distance of the Great Lakes Reproduce, develop quickly • 1 female = 1- 500 million eggs • Grow to ~10” in year 1 • Tend to jump when startled SILVER BIGHEAD BIGHEAD SILVER (From Mandrak and Cudmore and Kolar et al)

  6. Chronologic Upstream Movement of Asian Carp

  7. Stopping the Spread:Monitoring and Detection Positive eDNA Detections above barriers • Detection above barrier • Silver = 2.9% positive • Bighead = 5.7% positive • Monitoring • Netting, electrofishing, ballast sampling, tagging • eDNA tests above and below barrier

  8. Barrier Effect

  9. Stopping the Spread:Electrical Barriers Lake Michigan Water Flow • Barrier I (Demonstration): • In continuous operation since 2002 • - 1 volt/in, 5 hz, 4 ms • Rehabilitated in Oct 2008 • Other Ongoing Efforts: • Asian Carp Monitoring • Research on Optimum Operating Parameters • Study of Solutions to Potential Barrier Bypasses I • Barrier I (Permanent): • Upgrade to a permanent barrier authorized • Plan activation by 2013 if funded Chicago Sanitary and Ship Canal 800’ • Barrier IIA: • Activated @ 1 Volt/in, 5 hz, 4 ms in APR 2009 • Increased to 2 Volt/in, 15 hz, 6.5 ms in AUG 2009 • Maintenance shutdown completed Dec 2009 • Barrier IIB: • Site prep completed • Building construction contract NTP issued 3 Dec • Electronics design ongoing • Construction to be completed 30 Sep 2010 IIB 220’ IIA

  10. IIB To Lake Michigan IIA

  11. Barrier Status and Funding • Construction Status • Barrier I activated in 2002 • Barrier II A activated in 2009 • Barrier II B to be completed in late 2010 • Funding Status • Funding provided in federal budgets • Construction and operations

  12. Stopping the Spread:Rapid Response • December 2009, Barrier IIA down for maintenance • 400+ respondents, XX agencies and organizations • Results… • Barrier maintenance success • Confirmed presence of Asian carp in canal

  13. Strategic Framework: Short-and Long-term Actions

  14. Asian Carp Control Strategy Framework • Goal: Prevent establishment of self-sustaining carp populations in the Great Lakes • Integrate and unify future actions of participating agencies, develop collaborative approach • Transition to multi-tiered defense (beyond barriers) • Dynamic document based on growing body of knowledge gained from research and monitoring • Strategy: “…move quickly on proven solutions, and consider, develop, and test potential solutions and employ those that are most sound.”

  15. Framework:Short-term Actions • Carp population suppression measures • Enhanced detection measures • Increased sample collection • eDNA indicator refinement • Structural operation variations • Emergency engineering measures • Expedited biological control assessments • Enhanced electric barrier operations

  16. Framework:Long-term Actions • Efficacy study • Inter-basin feasibility study • Ecological-separation • Modified lock operations • Commercial market enhancement and ongoing fish population suppression • Biological controls

  17. Framework:Funding • Short-term actions • $38.6 million • Long-term actions • $39.9 million • Funding Sources • Great Lakes Restoration Initiative: $57.4 million • Base Program Funding: $21.1 million

  18. The Future:Ecological Separation? • Ecological separation means… • NO interbasin transfer of aquatic organisms • PREVENT the movement; 100% effectiveness • Ecological separation does not necessarily mean… • Stopping shipping or recreational traffic • Lock closure • More frequent or more severe floods

  19. The Future:Ecological Separation? • Ecological separation might entail . . . • New infrastructure • E.g.: Lift lock for recreational vessels, similar to the Big Chute Marine Railway on the Trent Severn Waterway, Ontario • Chemical/heat barriers • Altered traffic flows (commercial and recreational navigation) • Changes to hydrology • Different management of stormwater and wastewater • Improved transportation infrastructure • Enhanced infrastructure for tourism • Ecological restoration of waterways

  20. The Future:Ecological Separation? • USACE “Feasibility Study” • Corps authorized to investigate “range of options” for separation • Multi-year study • Other elements for others: • Investigate the transportation and water management needs for the region; • Propose new infrastructure needs; • Take into consideration all connections that need to be severed.
