Algal Blooms

In the 1960s:

  • Lake Erie was

declared “dead”

  • Excessive algae

became dominant species

  • Massive fish kills;

fouling beaches and shorelines

Flashback

In response to public concern and recommendations by the IJC, The Great Lakes Water Quality Agreement (GLWQA) was signed by Richard Nixon and Pierre Trudeau in 1972

SLIDE 4

The Great Lakes Water Quality Agreement 1972

Established a Total P target load of 11,000 Metric Tonnes per year for Lake Erie Actions Taken:

  • Eliminated

phosphorus in laundry detergents.

  • Limited the

discharges from Industrial and Wastewater Treatment Plants. Identified Total Phosphorus as a cause of massive algae blooms.

What are Harmful Algal Blooms and why are we concerned?

 6-7 species of

cyanobacteria (blue green algae)

 Capable of producing 4

toxins (e.g. microcystin)

 Require high levels of

nutrients and warm water (above 60F)

 Can cause human and

animal illness and death.

What accelerates algae blooms?

Sunlight Warm water Calm, stagnant conditions Phosphorus

Phosphorus is a Problem!!!

Drinking water for 11 million people,

Over 20 power plants, 300 marinas in Ohio alone, Walleye capital of the World, 40% of all Great Lakes

Charter boat, $1.5 billion sport fishery,

  • ne of the top ten sport fishing locations in the World, the

most valuable freshwater commercial fishery in the World, coastal county tourism value

  • ver $10 billion.

LAKE ERIE ECOSYSTEM PRIORITY (LEEP)

MAIN GOAL “In 3 years, we will have measurably reduced DRP (dissolved reactive phosphorus) loads and

  • algae. We will have a better scientific

understanding of causes and controls and an adequate monitoring system in place. We will have improved coastal resiliency and governance as well as better public understanding and support…”

Priority Strategy/Timeline

 Develop Series of Draft Papers and Reports on Science and

Social/Economic Aspects by December 2012

 Lake Erie Workshop in February 2013 to Review Draft

Papers/Reports and Develop Draft Findings and Recommendations for IJC Report

 Develop Interim IJC Report by May 2013  Public Consultations on Draft Report from May-July 2013  Finalize IJC Report with Key Recommendations to the Parties

at Great Lakes Summit Fall 2013

 Develop IJC Workplans for Following 2 Years (Governance

and Implementation Issues will be the focus in this phase of work plans)
