Based upon this evidence, we will need to set up a monitoring program. This exercise was very specific in directing students to research this information in the textbook, the field manual, and other sources. Often measured by using a secchi disk, turbidity is a measure of water clarity. Increases in turbidity indicate more suspended solids in the water, reducing the transmission of light. Phosphorus is a nutrient needed for growth in plants and animals.
Excess phosphorus can increase algal growth, which can cause a greenish tint to the water.
Increases in algal growth can cause cultural eutrophication, decreasing the oxygen levels in the water. A physical description of the algal content in the water through visual observation. A visual estimation of the strength of the wind, which can affect the water surface. A visual estimate, which can indicate recent precipitation or runoff. Oxygen is necessary in the water for plant and animal survival.
