What factors influence the temperature of water?
1. The amount of shade provided by surrounding trees help cool the watershed. When people cut down trees this often causes soil erosion, which can increase the amount of suspended solids in the water. As a result, the turbid water s particles absorb the sun s rays, which cause the water temperature to increase. 2. The depth of the watershed allows deeper waters to remain cooler than compared to shallow waters. 3. Cooler water temperatures are expected in the evening and warmer temperatures are expected during the day when the sun is out. 4. The reduction of water flow near operating dams may increase water temperature. 5. The air temperature which change seasonally. Water temperatures can range from 0 degrees Celsius in the winter to 30 degrees Celsius in the summer. 6. Confluence of streams. A natural method of cooling a body of water is the induction of colder water from a tributary. 7. Thermal pollution may cause a watershed s temperature to increase by adding warm water. Industries
