What characteristics of this lake make it "healthy"

1. Life- If you see fish in it, or moss, weeds, plants, etc. then that's a good sign of health. 
2. Color- If the grass is green and the water is blue, it's a good chance of good health! 
3. Natural Resources- If you see deer and other critters drink it, on many occasions, it is probably healthy. 
4. Food- If you have caught a fish from there and the fish was healthy, that's always a good sign! 
5. Infections- If you can dip a cup in the water and drink out of it without getting ill, that means it's probably healthy because a dead animal in it can easily spread disease or infection! 
6. The Surface- If you see dead fish, or oily looking liquid, that a sign that the lake is UN-healthy. 
7. Kits- A water kit is a simple way to tell if the lake is healthy or not. 
8. Oxygen- Lakes will provide oxygen and many other natural resources. That is a healthy sign. 
9. Minerals- If nature-made minerals are found in the lake, then you should be almost positive the lake is healthy. 
10. Pureness- If the water is pure, it is healthy. 
11. Motion- If the water is active, or you see waves or mainly any motion is a good sign of health too!
