Manitoba is home to many different lakes, such as Lake Winnipeg, the Earth’s tenth largest freshwater lake in the world (Mann, Anger and). The lake inhabits millions of fish and numerous beaches rest aside it’s shores. Although, upon the surface, clusters of tiny bluish green microorganisms can be seen. These organisms have invaded 50% of the lakes surface. (Burns, H20 and). The scientific name of these organisms are called “cyanobacteria” or in simpler terms, “blue green algae” Primarily, the presence of algae is regular on any body of water as it’s growth is promoted through nutrients such as phosphorus and nitrogen. So it would be completely normal for algae to be seen on the lake. Although, for the past ten years, Lake Winnipeg has suffered …show more content…
Although, Lake Winnipeg’s large body of 25,000 square kilometres makes it overwhelming to the point where the Government and environmentalists don’t know where to start. (Burns, Lake Winnipeg). Fortunately, The Lake Winnipeg Foundation is in the process of settling the “Lake Winnipeg Community-Based Monitoring Network”. This network will encourage citizens to take on the role of scientists and they will collect samples of different parts of the lake and send them to labs to test for levels of phosphorus. This will help scientists and the government gain knowledge of areas in the lake that are most at risk, leading them to take direct action. An obvious measure scientists would take is to reduce the nutrients in the lake. Based on this idea, Manitoba launched the “Lake Winnipeg Basin Initiative” in August 2012 with an investment of $18 million. In hopes up restoring the ecological lake of Lake Winnipeg by encouraging citizens to take part in the initiative, reducing transboundary pollution, working in close relations with other governments within the basin and improving water quality for the fishing industry and for recreational use. This initiative was set to happen from 2012-2017 (5 years). (Canada, Lake Winnipeg). Unfortunately, as of 2017 after the five year effort to lessen the phosphorus in Lake Winnipeg the decrease was less than 1%. Some actually found this decrease to be impressive as the quantity of phosphorus was immense. In hopes of increasing that percentage, Manitoba then launched a program called “Growing Outcomes in Watersheds program” A program which gives financial incentives to encourage farmers to adopt agricultural practices that involve less phosphorus. This will help reduce the amount of phosphorus getting into the lake through agricultural field runoff. (MacLean, After 5) As of now, 20-40% of phosphorus runoff that flows into Lake Winnipeg is insoluble.
Harrison describes Eutrophic lakes as highly productive and turbid due to algae being present. Furthermore Harrison states that oligotrophic lakes have low productivity and are clear in the
This climate and the shield itself allows for a Boreal ecozone with podzolic soil. The dominant trees are now Pine, Birch and Maple. Blackstone Lakes water is soft in comparison with the Great Lakes hard water. For comparison, Lake Ontario has over 200 ppm of dissolved solids whereas Blackstone has a value, measured in July 1969 by The Ministry of Natural Resources as 23 ppm.
For decades, there has been tension between Native American fishermen and non-native fishermen over the fishing rights on Mille Lacs Lake. This tension has increased, particularly because of the sustainability and quality of Mille Lacs Lake, and the Supreme Court’s ruling in Minnesota against Mille Lacs Band of Chippewa Indians. The Court claimed that the Chippewa Indians retained their rights to hunt and fish on ceded lands as established by the 1837 Treaty of St. Peters. Usufruct rights are rights of enjoyment to another’s property allowing the holder to generate income from the property without obtaining ownership. This right to hunt and fish on ceded lands is further protected from state regulation by the 1837 Treaty of St. Peters.
Although beneficial, the removal of sediment within bodies of water is of a costly nature and is usually a last resort. (Lenntech,
Dr. Harvey Bootsma discussed the changes the Great Lake faces from invasive species and prevention because in 2050 the Great Lakes will be U.S.’s most valuable natural resource with 20 percent of world’s freshwater. “It’s hard to manage a system when it’s always changing,” said Dr. Harvey Bootsma, Associate Professor for School of Freshwater Sciences at the University of Wisconsin-Milwaukee.
On the shores of the Attawapiskat Lake, about 18 hours north west of Barrie, lies the band of the Neskantaga First Nations, where only a portion of the population remains. The other portion leave, because of the large amounts of poverty and the isolation. This First Nations Community has been under a water boil advisory for over 20 years. Their current water filtration system hasn’t worked since 1995, and even when it did work it removed sand and grit, but left in harmful chemicals. The government gives the Neskantaga people $250,000 annually, which goes towards running a water treatment system that continuously tests positive for harmful chemicals after being filtered.
but it is in trouble because of pollution and other threats to the Great Lakes. Because it is such a large part of the logistics picture for Michigan I think they will find a way to minimize the negatives and make this process as efficient as
THE ZEBRA MUSSEL INCIDENT The Zebra Mussel Incident Zebra Mussels are an invasive species which now dominate the Great Lakes region, they were introduced in the 1980’s and ever since then their quantities have increased dramatically. Since the time they arrived they have caused many problems including problems in the ecosystem and with the economy. Human’s have been trying ever since their arrival to eliminate or reduce their quantities but not much progress has been made. Right now Zebra Mussels are one of the biggest issues affecting the great lakes.
So many things rely on the water that if it were to be contaminated, there would be a chain of unwanted results. Luckily, the state of Minnesota takes extreme caution to protect its most abundant
However, how does Canada compare with a similar country? America, being Canada’s neighbor, also owns a portion of the Great Lakes and shares similar conditions with Canada. Forcing them to face the same issue being the algal blooms of the lakes. These hazards altering the behavior of the environment and the ecosystem itself, algal blooms can cause trophic cascades: when the predators of the food web suppresses the abundance or alters the behavior of their prey (Stephen Carpenter, 2016). This results in dramatic changes in the ecosystem structure and nutrient cycling in the environment.
However, an overabundance of some nutrients, such as nitrogen and phosphorus, impairs water quality. “Agriculture is the largest source of pollution to the Chesapeake Bay and its rivers and streams.” quotes the Washington Post (Baker, 2015). About 50% of phosphorus and 40% of nitrogen dumped into the bay stems from agricultural runoff. According to the Chesapeake Bay Foundation, “Each year, roughly 300 million pounds of polluting nitrogen reaches the Chesapeake Bay—about six times the amount that reached the bay in the 1600s.”(cfb.org). The major sources of the excess nutrients comes from over fertilization of crops with animal manure seeping into waterways, and animals having direct access to waters where waste is carried into the watershed (Baker, 2015).
The Great Lakes had many benefits for Canada, which include: the transportation of goods, home for many aquatic species, and the provision of drinking water. Although, the lakes provided a great abundance to Canada they became over polluted after World War two, leading to a challenge Canada had to face. As a result “The Canadian Government became aware of the pollution in the great great lakes, to reduce the problem the Great Lakes Water Quality and Clean Water Act were created.” (www.Great-lakes.net)
Eutrophication, which is excessive richness of nutrients in any form of body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen, is another reason why the creek could be polluted. Fertilizers are used in farming to provide crops with nutrients, but they also play a big role in the Eutrophication process. If too much fertilizer is used, it leaches from the soil in
We took a large net and set it vertically in the water, and then somebody got in the creek and kicked up sediment into the net. After doing this a few times, we collected all of the creatures off of the net and into an ice cube tray. We then examined the creatures and noted the variety (or lack thereof) of the creatures. The larger the variety in the species of the creek, the healthier the creek is. We noticed several species of fly larvae such as stone fly larvae and caddis fly larvae. We also noted a few worms.
Undoubtedly, there are many factors that can impact temporal patterns as illustrated in the climographs. Both of the cities is located in a different part of the world and experiences different climates. Each of the cities have very different geographical layouts and factors that affect temperature and precipitation throughout the year. In Toronto, Canada climate is moderate with warm humid summers and generally cold winters. The climate in Toronto, Canada is moderate due to its southerly location within the country and its proximity to Lake Ontario.
