| Stream Name: KEITH CREEK | Survey Date: 2023-08-13 |
| Organization Name: PSKF | Project Name: |
| Stream Segment #: | Stream Section #: |
| Data entered by: Lauren Woschee | Survey ID: 117 |
Step 1. Benchmark Location
| Directions to Benchmark: Parked by Loutet farm and walked down towards bike park then down trail to the right of the bike park to reach the creek. Beside the creek there is an old mining slough and benchmark is ~15-20m downstream from there. |
Step 2. Cross-Sectional Survey
