Preservation Restoration Of Degraded Or Low Quality Lakes

: Larchwood Lake may not ever be the same again. The story about Larchwood Lake is not that uncommon. Without doing extensive research into possible things that could occur by lowering the lake level, the Larchwood Lake Homeowner’s Association destroyed the very thing they were trying to protect. Carelessness and poor planning are not the only root causes however. There are a number of reasons that led to the degradation of Larchwood Lake that happen to relate to more macro level environmental issues. Those reasons are poorly designed environmental policy created by the E.P.A., poor understanding of lake ecology by the managers of the land, and false confidence in poorly planned ideas. By looking at how these factors contributed to the degradation of the lake, hopefully we will be able to make more ecological sound decisions in the future.

Brooks and Dodson, the authors of the article titled “Predation, Body Size, and Composition of Plankton”, conducted research on the effect the small fish called Alosa Pseudoharengus has on an ecosystem, more specifically, different lakes in New England. Along with the data they collected on the aforementioned matter, they studied the sizes and the composition of the miniscule zooplankton inhabiting the lakes, and compared it with that of the Alosa. Their research uncovered important facts regarding water ecosystems and how they are so easily thrown off balance.

More than 24 billion gallons of untreated sewage waste and storm water are pumped into the lakes annually. Pollution is increasing as well, due to the cottage development, where people enjoy spending their summers relaxing. For many years, the lake habitats have been affected by pollution and habitat destruction. The market for fish is tremendous; so much so, that we have depleted our fishing resources, and have had to market on invasive species.

Back in the 1960’s, Lake Erie was declared “dead” because, ironically, it was full of life – just not the right kind (GLIN, n.d.). The algal blooms that formed due to high concentrations of nutrient-loaded city street run off invaded the freshwater lake, killing native species, reducing oxygen quantities, and smothering beaches with its slime (GLIN, n.d.).

Phosphorus, “...the primary algae-feeding nutrient in Lake Erie, and contributed to the largest algae bloom in history last year” (McCarty, para. 3), is a key factor in how

While in many ways the two lakes share similar attributes, they can also be observed as their own entities. Each lake containing characteristics that make them preferred for some species types. In addition, the region shares some environmental concerns. Those concerns pertaining to invasive species as well as poor water quality. Both of which impact the physical characteristics, and natural life of the organisms that make up the many different habitats the region

The Bosherston Lakes are man- made water bodies own by the National Trust, Stackpole National Nature Reserve and the lakes are made up of four hallow lakes (about -2.5m deep) and is formed by frowning and damming three valleys in the Carboniferous Limestone of coastal Pembrokeshire valleys in the eighteenth and nineteenth centuries. (Overleaf figure 1.). And Bosherston lakes is managed by the National Trust in partnership with the Country Council of Wales and have been classified under the EC Habitat Directive as a Special Area of Conservation (SAC) .(Ree et al., 1991). In (figures 2 overleaf) which shows

Tuggerah Lakes have been a popular commercial and recreational fishing venue for more than a century. Not only have they been one of the most important producers of estuarine fish in NSW, but have attract many tourists to the area each year.

The wild life of Lake Argyle is very inhabitant, as there were many beautiful and majestic creatures that weren’t so shy to expose themselves to our presents. The wild life plays a huge part in this man-made lake, because not

As the afterbay to Folsom Dam, Lake Natoma is essentially a wide spot in the American River characterized by sheltered waters and a highly scenic setting. As on Folsom Lake, the primary visitor areas on Lake Natoma accommodate multiple recreation uses and are separated by underdeveloped shoreline. These areas include Nimbus Flat, California State University Sacramento(CSUC) Aquatic Center, and Negro Bar. The Nimbus Flat visitor area, located on the eastern shore of the lake just above Nimbus Dam, includes two smaller beaches, landscaped picnic areas, low docs for launching small watercraft, and restrooms. The CSUS Aquatic Center, which is operated by Sacramento State University under agreement with State Parks, is home to the university’s water

Sarasota, Florida is home to the wonders of the Gulf Coast and the cool, crisp daily breezes, sandy beaches and desirable lifestyles. Perfectly located in the center of Sarasota lies the neighborhood community of Forest Lakes. The community features over 700 single-story ranch homes with spacious front and back yards and finely manicured landscaping. Many of the homes offer residents majestic mountain views. The majority of the homes were built in the 1960s, but the community beautifully maintained or updated the homes over the years.

Shallow lakes tend to be more productive than deep lakes, in part because they do not stratify, this allows nutrient to remain in circulations and available to plants. They also tend to have smaller lake volume, so there is more nutrients available. Also, shallow waters have more sufficient light to support photosynthesis which cause an increase in productivity. The productivity of shallow lakes is correlated with the higher water-sediment interface per water volume.

Biogeochemical cycles are important to the sustainability of all life. Chemical elements necessary for the growth and reproduction of all organisms have a limited quantity on earth at any one time, other than the occasional meteor that brings with it new matter. It is therefore important that the recycling of these chemical elements is efficient. Autotrophs are the basis of almost all ecosystems. The rate that autotrophs produce and transfer energy is vital to the capacity of organisms that can inhabit these ecosystems. To understand the rates in which certain species’ leaves decay and release the energy stored within them can demonstrate how quickly the energy becomes available to organisms in higher trophic levels.
