1 Summary Overview Primary Headwater Habitat Assessment

2 The Assessment Process Desktop Evaluation (4 steps) Field Reconnaissance 1 and Sampling (7 steps) Final Report (1 step)

3 Desktop Evaluation Step 1- Obtain maps Step 2- Determine stream length Step 3- Determine area of watershed Step 4- Prepare for proper evaluation

4 Field Reconnaissance and Sampling Step 5- Determine if baseflow conditions are present and determine if Q7-10 conditions are present Q7-10 is the lowest average, consecutive 7- day flow that reoccurs with a frequency of once in every ten years.

5 Field Reconnaissance and Sampling Step 6- Flag stream reach sections

6 Field Reconnaissance and Sampling Step 7- Record data on PHWH form, take pictures

7 Field Reconnaissance and Sampling Step 8- Conduct water chemistry sampling

8 Field Reconnaissance and Sampling Step 9- Conduct biological survey First - salamanders, Second – fish Third – macroinvertebrates Collect voucher specimens

9 Field Reconnaissance and Sampling Step 10- Measure the three metrics

10 Field Reconnaissance and Sampling Step 11- Conduct optional habitat measures Gradient Flood Prone Width Quantitative Pebble Counts

11 Final Report Step 12- Determine appropriate aquatic life use designation Biological survey trumps HHEI survey

12 You have now successfully surveyed a PHWH stream.

13 Glossary Reconnaissance- The active gathering of information about conditions. Delineate- To trace the outline of.
