Ohio later on! The lake was polluted and wanted to fix it so we did but‚ we ruined the lake once more 40 years later. “First‚ As a result of these pollutants‚ Lake Erie contained increased levels of phosphorus and nitrogen‚ which contributed to eutrophication - a process that encourages the development of algal blooms.” (Rotman) It was called “burning river” or “dead lake”. In 1960 the lake was a terrible it seemed to be like a swamp with lots of algae. It was so bad they said It was easier to travel

DO gets into the water in many different way but primarily it is absorbed from the atmosphere and aquatic plants. 3. Why is it important? DO is important because it provides oxygen to aquatic organisms and without it they wouldn’t be able to live. Low levels would cause hypoxia and make it extremely difficult for

The water of the UHigh Creek is excellent‚ however some creeks have been polluted and overall have a worse water quality. There are a few different ways a pond or creek can become polluted. One type of pollution caused by humans is Eutrophication‚ which starts when farmers put fertilizers on their crops. The fertilizer can be washed off from the rain and can carry it to a nearby stream or lake. The nitrates and phosphates that are being put in the water fertilize algae and cause its population to
