The Main Impacts include:

1. Loss of Land

Flooding permanently removes land from productive use. This may include:

• Agricultural land
• Forests used for hunting and trapping
• Fishing areas
• Residential areas
• Sacred and burial sites
• Traditional travel routes

Unlike privately owned land, reserve land is often central to the community's cultural identity and traditional way of life.

2. Economic Losses

Hydroelectric projects can significantly impact the economic opportunities available to a First Nation.

Examples include:

• Loss of agricultural production
• Loss of commercial timber
• Reduced hunting and trapping income
• Reduced commercial and subsistence fishing
• Loss of tourism opportunities
• Reduced opportunities for future economic development

These losses may continue indefinitely if the flooded land cannot be replaced.

3. Environmental Impacts

Flooding changes the ecosystem by:

• Destroying forests and wildlife habitat
• Altering fish populations and spawning grounds
• Increasing shoreline erosion
• Affecting water quality
• Releasing mercury from flooded vegetation, which can contaminate fish for decades

4. Cultural and Spiritual Impacts

Many reserve lands contain:

• Burial grounds
• Ceremonial sites
• Historic settlements
• Archaeological resources
• Places used for traditional harvesting and teaching

Loss of these sites cannot easily be measured in monetary terms.

5. Social Impacts

Flooding may force communities to:

• Relocate homes
• Change traditional lifestyles
• Lose access to harvesting areas
• Experience unemployment
• Suffer community disruption

The effects often extend across several generations.

6. Loss of Treaty and Aboriginal Rights

Although treaty rights themselves are not extinguished by flooding, their practical exercise may be impaired when:

• Hunting grounds disappear
• Fishing locations become inaccessible
• Traditional travel routes are submerged

Canadian courts have recognized that government actions that significantly interfere with these rights may give rise to legal remedies.

7. Reduction in Property Value

From an economic perspective, flooding may reduce:

• The market value of reserve land
• The highest and best use of the land
• Future development potential

What we often estimate:

• Market value before and after flooding
• Present value of future income losses
• Loss of use over time
• Replacement costs
• Opportunity costs

8. Ongoing Costs

Even after construction, communities may incur continuing costs such as:

• Shoreline stabilization
• Infrastructure relocation
• Increased transportation costs
• Water management expenses
• Environmental monitoring

Methods Used to Estimate Economic Damages

In litigation, experts commonly estimate damages using one or more of the following approaches:

The appropriate method depends on the nature of the loss and the available evidence.

Canadian Examples

Several major hydroelectric projects have resulted in claims by First Nations, including:

• James Bay Project
• Churchill Falls Generating Station
• W.A.C. Bennett Dam
• Kettle Generating Station
• Keeyask Generating Station

These projects have generated litigation and negotiated settlements involving compensation for flooded reserve lands, lost economic opportunities, and impacts on treaty rights.

Relevance to Specific Claims

In the context of a Specific Claim under Canada's reserve land framework, we will quantify losses under several heads, including:

• Compensation for the value of reserve land taken or flooded.
• Loss of use of reserve land from the date of flooding to the present.
• Lost income from agriculture, forestry, trapping, fishing, or other commercial uses.
• Loss of future economic development opportunities.
• Costs associated with relocation or mitigation.
• In some cases, compensation for cultural and environmental impacts where recognized by law or settlement.
