There are many different types of lake restoration methods. Each lake restoration technique offers its own benefits but all have the same goals. Because of their low impact on ecosystems, chemical treatments are often the best option for restoring lakes. However, their application is limited. Hydro-raking is another technique that can be used to remove deep-rooted aquatic plants. A full excavation is the total draining of a lake, and the replanting native species.
No matter what method is used to restore a lake's water quality, the goal of any restoration effort is to lower the level of phosphorus and nitrogen in the water. There are many ways to control nutrients from point or diffuse sources, but it is difficult to restore a lake with a high concentration of both nutrients as well as their metabolites. In winter, the optimal concentrations of phosphorus as well as nitrogen should be below 0.05 mg l-1. However, this value can vary greatly between lakes. Biomanipulation is the removal of fish from a lake.
The ecosystem can be affected by sedimentation in lakes. This is because sediments reduce the amount of sunlight available to primary producers, and also destroy benthic food organisms. In addition, sedimentation can be expensive and affects the environment in surrounding areas. The high cost of remediation can lead to damage to the lake's environment.
A healthy ecosystem requires that lakes and waterbodies have an adequate balance of carbon dioxide and oxygen. This balance is known as dissolved or oxygen (DO). Both animals and plants need oxygen for survival. Low levels DO can indicate that a waterbody is in need of remedial actions, such as restoring balance to a lake. This article discusses how to measure water quality and manage waterbodies so that you can achieve these goals.
India's waterbodies is declining in number. In 1960, Bangalore had 262 lakes. Today, only ten lakes are found in Bangalore. Ahmedabad's lake count is 65 less than 2001. Hyderabad has lost more wetlands than 3000 hectares over the past 12 years. This limits the ability of waterbodies provide many services. Although waterbodies are protected by adequate laws, these laws are not always effective.
Scientists are also investigating the impact of climate changes on lake ecosystems. Changes in temperature and precipitation patterns could worsen eutrophication. Increasing DOC can cause nonlinear effects in water column biogeochemistry. These responses are easily captured with numerical models. One example is a computer-generated model that can predict the effectiveness and efficiency of a restoration technique.
Sam Robinson has over 15 years experience working with lakes. His knowledge of lake ecology has made Sam Robinson a trusted partner in many state projects. He also helped create watershed plans for Minnesota's lakes. The company provides many services including dam modification and outlet design, as well as rock arch rapids and environmental restoration.
