Questions to Answer:
1. Define and/or explain the parameters assigned.
2. Why are these parameters useful/important in assessing stream health?
3. Explain the nature of the tests performed to assess these parameters, and the theory behind each test.
4. Where relevant, state the allowable levels for each parameter.
5. Present data and compare to allowable levels.
