| Stream Name: THAIN CREEK | Survey Date: 2023-07-29 |
| Organization Name: PSKF | Project Name: |
| Stream Segment #: | Stream Section #: |
| Data entered by: Lauren Woschee | Survey ID: 115 |
Step 1. Benchmark Location
| Directions to Benchmark: walked in from corner of 17th St and Wolfe St down the stairs - headed south on path and went to area that many people go up and down to stream. Tires in stream and concrete cylinder blocks in stream. Wide open are (might consider planting here) |
Step 2. Cross-Sectional Survey

| Location relative to benchmark: same location as benchmar | Photos Taken? yes |
| Bankfull Channel Width: 3.80 | Average Bankfull Depth: 18.53 |
| Wetted Channel Width: 3.20 | Average Wetted Depth: 5.67 |
| Measurements taken every 0.50 metres | Number of measurements taken: 15 |
First and Last Measurements Taken .1m from the streambank edge
