Lake Findings Report:
Heather, Jackie, Kitt, Sira, on The Missouri Lake:
Our lake is located in Missouri. Here are directions to the lake: Take interstate 27 south for about 37 miles. follow U.S. Hi way 69 south for about 82 miles, then take state Highway 340 west about 15 miles. Turn onto and follow Country Road H north for 6 miles. you will see the town and the lake on your left. Some of our major problems in our lake are that there is green scum floating on the water. It is covering docks, piers,rocks, etc... Our present condition is that the water is green and less transparent, Also there are fewer fish and shore birds, there are more mosquitoes. Around our lake we have frogs,Buffalo head duck, deer flies,beetles,bobcats,garter snakes,bald eagles, white ash, American beech, and cat tail. those are some of the plants and animals around our lake. Some of the bigger animals are leaving the area in search for food. In this report IÕm going to talk about some main points such as photosynthesis, PH, soils, erosion, pesticides, problems, and solutions.
Photosynthesis is the production of energy from the sun. PH is what you use to judge the acidity of a substance. The thing used in the photosynthesis process are light, water, hydrogen, and CO2. The things that are taken out of the photosynthesis process are sugars, and oxygen. Photosynthesis has an important place in the food chain. Plants produce oxygen while animals and humans consume it. Animals consume oxygen in the air when they breath in and let out carbon dioxide when they breath out. even water plants such as algae produce oxygen. carbon dioxide is produced by animals breathing it out and also from dead plants and animals. Photosynthesis also has a lot to do with the PH value of water and the transparency of water. An example is if the water is less transparent and a base on the PH scale then there is a lot of photosynthesis taking place. Another example is if the water is very transparent and is an acid on the PH scale then there is little photosynthesis taking place. A seechi disk can tell how far down the photosynthesis can grow. The disk does this by going down in the water and when you canÕt see it any more that is the point to were photosynthesis can take place. That is how photosynthesis and PH takes a major part in our lake
There are many things that contribute to the erosions of soils. Some of these things are earth quakes, trees falling over, rock slides, rain farming, etc... The main reason though is the steep slope of our lake. Our lake has a slope of 10%. Most of the hills in San Fransisco, CA have a slope of 17%, so that makes our slope pretty steep. The four cycles that effect erosion are the water cycle which effects acid rain, the oxygen cycle, the nitrogen cycle, and the photosynthesis cycle. Erosion effects our lake because it makes it so minerals can drain into the lake. Pesticides drain into the lake and so do others. That is how erosion effects our lake.
A pesticide is a chemical which kills specific pests. A pest is any unwanted plant or animal. Pesticides run into lakes by runoff from rivers and snow. Pesticides are produced to kill pests. Some factors that effect the amount of pesticides in our lake are how much pesticides are sprayed, how much water is in the lake, how much erosion takes place, and how much it rains. In our lake, we have three hundred micrograms per liter of pesticides. That is a lot. That is all about pesticides in our lake.
Some of the problems we have at our lake are, it smells like rotten eggs because of the sulfur, fish are dying because of the rotten egg smell caused by sulfur and nitrogen, The last problem is that animals are leaving because of the lack of food. These problems are affecting the food chain by killing animals in it and shrinking the food chain. Some of the ways to solve the problems at our lake are to cut down on fossil fuels, bubble pure oxygen into the lake, not to dump into the lake, pass a law to protect trees, reroute sewage to other places, add predators to get rid of unwanted pests, place fines on polluters, and last but not least reduce the amount of nitrogen in the fertilizers. This is the end of our lake report and I hope you learned some thing from it. on the next page are some graphs on nitrogen levels, oxygen, and some other things.
