Loueberry Lake Essay

Introduction: The purpose of this research is to determine whether there has been a change in the overall water quality of the Lake Tarpon Basin, and if so, whether the quality has improved or worsened. The variables that will determine whether the quality has changed are: nutrients (phosphates and nitrates) and dissolved oxygen (DO). The expected changes are lower dissolved oxygen levels (from the already low levels), higher nitrogen levels (from the already high nitrogen levels), and the state qualifications still are not met for nutrients and dissolved oxygen (Levy, Flock, Burnes, Myers, Weed, River 2010). This topic relates to environmental management because the changes in water quality would be due to pollution, which relates to the question “How does human activity lead to the pollution of water stores?” The hypothesis that will be tested is that Lake Tarpon’s water quality will have worsened since the last measurements by Levy, Flock, Burnes, Myers, Weed, and Rivera in 2010.

Exercise Lab 1. How much does temperature vary in large and small aquatic environments? Lab 2. What determines the water clarity of lakes, rivers and oceans? Lab 3. Where does the phosphorus go? Lab 4. How does human activity in watersheds affect the quality of lakes and rivers? Lab 5. Are the Great Lakes being influenced by the global greenhouse effect? Lab 6. How is the flow of the Red Cedar River influenced by the weather? Lab 7. What is the relationship between flow and turbidity in the Red Cedar River? Page 2 4 6 8 12 15 18

To assess and analysis the long term trends and seasonal trends of Phosphorus in relation to the lakes system within the catchments.

The water in urban wellfields is contaminated with saltwater since the water flow had changed direction. The water also contains high levels of nutrients (particularly phosphorous) because of runoff from the developed areas.

Although the amount of pollutants from a single town or construction site may seem insignificant, the combined concentrations of contaminants threaten our lakes, streams and wetlands. When things such as: human and animal waste, decaying plants and animals, discarded litter, or food waste enter surface waters, either dissolved or suspended in stormwater runoff, they can deplete the supply of dissolved oxygen in the water. When dissolved oxygen is reduced below a certain critical level, it can impair or kill aquatic plants and animals (CNYRPDB, 2011).

Back to the history, the eutrophication problem was first time concerned by public on Great lakes at the 1960s, the Lake Erie was covered by algae as a result of over dumped phosphorus from the sewage and other waste water, at that time, the Lake Erie was known as the “Dead Sea of North America”(Fitzpatrick, J. J., and Di Toro 1999). The reason cause this problem can be concluded in 2 points, 1. the stresses of overfishing, 2. development of phosphorus-based detergents. At the end of 1960, the Canada and the United States have realized the penetrance of this problem and finally sit on the table to sign an agreement that limiting phosphorus dumps to the Lake Erie, and plan to control existing unstoppable algal growth. Because of the awareness of Canada and US government, the concentration of phosphorus got a significant success. And this problem happened again during the 1990s, but this time the reason why this happen is more complexly.

Lake Toba is located in Sumatra, Indonesia (Figure 1). The Toba Eruption was the last of three major eruptions, which occurred over the past million years, creating a volcanic caldera1. The most recent eruption, also known as the Youngest Toba Tuff erupted around 73,000 (± 4000) years ago2. This created a global catastrophe that effected many species, including humans. Many researchers have linked this even to the most recent bottleneck in human evolution resulting in a dramatic drop in the human population to only about 3,000 to 10,000 in a very short period of time3.

Often when people think of Olympic host cities, they conjure up massive cities in their minds. Lake Placid does not align with that ideal. We prefer the term village to city. Because of our smaller size, people do not think that we are equipped to host the Olympic Games. We may be small, but the village of Lake Placid is a specialized city that focuses on recreation, especially winter sports. Lake Placid has been engineered to host events such as these Olympic Games.

The purpose of this experiment is to understand the effects of nutrient enrichment and eutrophication, using samples of water from Rio Salado and Encanto Park. The samples will contain different concentration levels of nitrogen, phosphorous and nitrogen and phosphorous combined and the impact it has on algae growth. The results recorded showed that the nitrogen concentration levels had a little change, phosphorous levels had a higher change and phosphorous and nitrogen combined had a significantly higher change, resulting in higher algae growth. The results showed that phosphorous indeed is a limiting nutrient in algae growth, but to achieve the highest growth rate, both nitrogen and phosphorous need to be combined.

Our plan is research the phosphorus levels in Lake Monroe and Griffy Lake and compare them in terms of area surrounding and the impacts it has on the City of Bloomington. Due to the proximity of agriculture around Lake Monroe and Griffy Lake, we want to research the effects of agricultural practices such as pesticides on water. Specially, we want to see if there are differences between the body of water we use as a drinking water source, Lake Monroe, and Griffy Lake. We think it will be beneficial to compare the chemical levels in both bodies of water and evaluate the differences.

He had my hand in his, pulling me towards the lake so that we faced the liquid topaz.

- Can interagency cooperation increase authority or target funding for specific invasive species like hydrilla in Florida? Working groups set the plans.

Phosphorus and nitrogen offer the largest increase in growth of the algal biomass, due to both being limiting factors, as the algae relies on them to survive and reproduce. Though the addition of silica increases this even more, on their own no one nutrient is enough to create a balance. To keep a reign on algae blooms and create a sustainable environment for the lake, maintain the proper levels of nutrients near shore. That green muck you see isn’t entirely bad, it does a lot of important things so long as it’s not getting out of control. Take care of the phytoplankton, and it will take care of

For there lay the lake. Not a lake, the lake, the lake that had been featured in every single one of her father’s tales, be they stories of ancestors or stories of his recent days; the lake that had provided a countless number of shops around the world with authentic Icelandic arctic char, the lake that had started and upheld and would continue to uphold the Heath family legacy for every conceivable generation to come.

(London 4) Too much phosphorous promotes excessive algae and plant growth, leading to harming the water quality, as well as decreasing the amount of oxygen in the water that many aquatic lifeforms need to survive. Algal blooms, excessive algae growth, will cause deaths to large amounts of fish and also harm humans if they come into contact with the polluted water or consume the affected organisms living in the algae-infested water. (United States Environmental Protection Agency) An example of widespread algal blooms is shown in Figure 2 where much of the visible water is covered in algae, slowly suffocating the life that lives within the water.
