Lake Erie needs cut in phosphorus The Columbus Dispatch (2/28) Sharp cutbacks in phosphorus runoff into Lake Erie are needed to counter a worsening problem of algae blooms that degrade water quality, harm fish and chase away tourists.
Lake Erie's algae blooms threaten its survival CBC News Canada (2/26) During the summer months, Lake Erie smothers under huge blooms of green algae, often thousands of square kilometres in size, which threaten the lakes' existence.
Great Lakes Areas of Concern (AOCs) are severely degraded geographic areas within the Great Lakes Basin. They are defined by the U.S.-Canada Great Lakes Water Quality Agreement (Annex 2 of the 1987 Protocol) as "geographic areas that fail to meet the general or specific objectives of the agreement where such failure has caused or is likely to cause impairment of beneficial use of the area's ability to support aquatic life." The U.S. and Canadian governments have identified 43 such areas; 26 in U.S. waters, 17 in Canadian water (five are shared between U.S. and Canada on connecting river systems). Collingwood Harbour, in Ontario, is the first of these 43 sites to be delisted.
The Great Lakes Water Quality Agreement, as amended via the 1987 protocol, directs the two federal governments to cooperate with state and provincial governments to develop and implement Remedial Action Plans for each Area of Concern.
