Great Lakes Flooding

After a spring of unusually heavy rain throughout the Northeast, many lakes and streams have risen to flood level. This is particularly

problematic along the southern shore of Lake Ontario when there is a strong North or Northeast wind. Although I could not get to the exact same position, due to flooding, the photos show Durand-Eastman Beach is essentially gone for most of this season. This flooding event is politically controversial because it pits U.S. Lake Ontario and Canadian Montreal residents, and conservationists against each other. As reported in Rochester’s City Newspaper, Lake Ontario’s level was 33.1 inches above its long-term average on May 17, according to the IJC. However, in Montreal Harbor the water was 55.5 inches above average, causing evacuations of several neighborhoods. Although wider opening of the Moses-Saunders Dam’s  floodgates would have lowered Lake Ontario a little faster, greater flooding would have resulted in the Montreal area.

The U.S. Army Corps of Engineers and environmental scientists say that

heavy rain is the major contributor to flooding. However, U.S. Lake Ontario residents do not accept the scientific data. Instead, they claim flooding is the result of Plan 2014. Scientists project a $20 million loss under this plan, compared with $18 million under the previous Plan 1958DD. Therefore, if Plan 1958DD was still in effect, it would only reduce shoreline damages by 5%.

The primary reason for implementing Plan 2014 was to restore the lake shore habitat. The wetlands developed over centuries, through constant shifts in the lake’s water levels. However, in the late 1950s, U.S. and Canadian public power utilities built a large hydroelectric dam (the Moses-Saunders Dam) between Lake Ontario’s eastern outlet and the St. Lawrence River to minimize fluctuations in water level. The result is that Lake Ontario cattails have taken over vital coastal wetlands, leaving important species such as muskrat and northern pike without critical habitat.

The Nature Conservancy predicts that healthier wetlands will improve fishing, hunting, and other outdoor activities, along with greater economic returns. Healthier, diverse wetlands, especially healthy ones that are not overcrowded, filter nutrient pollutants – animal waste and all fertilizers – out of the water. Those pollutants encourage algae and bacteria growth in the waters near the Lake Ontario shore. Research indicates that healthier, more diverse wetlands could help reduce pollution, something that cattails are less effective at.

Even though property losses have dropped since the introduction of the dam, the IJC has to balance the need for environmental conservation with the needs of lake and river shore landowners. Unfortunately, landowners in each environmental area feel their property should be fully protected—an impossible task. When I discussed this with people I know, one said the shipping interests are the ones the governments are trying to protect, another said, you can’t believe what the government tells you. Although it is generally true that laws and regulations typically favor the moneyed interests, in this case the primary concern for governments is to balance the environment, commercial, and landowners’ needs based on what the current environmental science tells us about the shores of the Great Lakes. Ignoring this risks our grandchildren’s generation.

As I write this, the Trump Administration has not included monies for the Great Lakes Restoration Initiative. Although it has been reported that his budget proposal is “dead on arrival”, it remains to be seen whether this initiative will continued to be funded at an adequate level.
