Using the SAVi methodology, it calculates the value of services such as irrigation, water storage, nutrient removal, and carbon sequestration. The analysis finds that both assets are significantly more cost-effective than equivalent grey infrastructure. For Stephenfield Reservoir, the cumulative discounted value of enabled economic activity is CAD 6.07 billion by 2050, while replacing its services with grey infrastructure would cost CAD 5.33 million in capital. For Pelly's Lake, ecosystem services are valued at approximately CAD 60 million, whereas equivalent grey infrastructure would cost CAD 36.99 million.
