Adaptive Management
Recommendations
--- Please Select ---
Approve Lake Superior Plan 2012
Issue new Orders of Approval
Improve understanding of hydroclimatic processes & impacts
Apply adaptive management to address extremes
Establish Levels Advisory Board
Work with governments to fund and coordinate adaptive management
Multi-lake regulation should not be pursued
Remedial measures should not be taken in the St. Clair
Key Findings
--- Please Select ---
Future conditions are uncertain, so a new regulation plan must be robust
Plan 2012 will be more robust and provide important benefits compared to Plan 77A
Superior regulation has a small effect on Michigan-Huron levels
Increasing evaporation and precipitation are offsetting, except on Superior
Changes in levels may not be as extreme in the near-term as previously predicted
Nine decision criteria were used to evaluate regulation plans
Plan 2012 performs similar to Plan 77A under 20th century NBS
Plan 2012 helps Lake Superior during extreme dry conditions
Plan 2012 avoids serious impacts to Lake Sturgeon breeding habitat
Plan 2012 provides overall economic improvements
Plan 2012 flow changes will be smaller, benefiting hydropower
St. Marys River flows will be more natural under Plan 2012
Plan 2012 computer code is simpler and easier to manage
A new plan provides an opportunity to issue new Orders of Approval
Interests can adapt to historical range of levels; beyond this adaptive responses may be required
Restoration structures in the St. Clair are technically possible but costly
Restoring Michigan-Huron levels has both benefits and costs
Ecosystem impacts of restoring Michigan-Huron levels would be mixed
Institutional considerations of building new structures would be significant
Potential for multi-lake regulation to address extremes is limited
Adaptive management has an important role in addressing risk
Information and education are key to adaptive management
Adaptive management requires improved data, science, collaboration & integration
Adaptive management requires a modified governance structure
Adaptive management is relevant to other Great Lakes initiatives
Michigan-Huron to Erie head difference declined by 23 cm from 1963 to 2006
St. Clair River has changed, accounting for 7-14 cm of total head decline
Evidence suggests St. Clair erosion is not ongoing, but causes remain unknown
GIA accounts for 4-5 cm of total head decline
Hydroclimate accounts for 9-17 cm of total head decline
Lake levels are unpredictable
