ecological-economic context

Lake Erie provides drinking water to over 11 million people and produces more consumable fish than all the other Great Lakes combined. In the past 20 years, a decline in water quality from nutrient pollution has led to efforts by organizations, businesses, and governments, aimed toward better maintenance of this critically important source of freshwater. This report identifies and quantifies the improvement of key ecosystem service values and economic benefits in the region through water quality improvement, particularly phosphorous reductions in Lake Erie.

Economic BEnefits from Phosphorous REductions

The Great Lakes Water Quality Agreement's 40% phosphorous reduction, along with other benchmarks for phosphorous reductions, provide economic benefits to beach-goers, recreational anglers, property owners, and water treatment plants:
​Economic Benefit to Recreational Anglers
  • Achieving the 40% GLWQA phosphorus reduction target goal:  $31.3 to $123.4 million
  • Achieving a 20% phosphorus reduction:  $11.7 to $37 million
Economic Benefit to Beach-Related Recreation
  • 20% reduction in the number of water quality advisories and beach closure days: $23.8 to $26.7 million
  • 30% reduction in the number of water quality advisories and beach closure days: $36.2 to $41 million
Property Value Losses Avoided
  • Households within 20 meters (66 feet) of Lake Erie could avoid property value declines of $686 million.
  • Households within 20 meters to 250 meters (66 feet to 820 feet) of Lake Erie could avoid property value declines of $1 billion.
Potential to Reduce Water Monitoring and Treatment Costs Associated with Algae​
  • In total, water treatment plants incur $3 million in annual costs
    • U.S. plants incur $2 million in annual costs
    • Canadian plants incur $889,778 in annual costs (2018$ USD).
  • Capital expenditures for algae-related projects total over $85 million to date.
