Monitoring Bacteria and Macroinvertebrate Life in Local Creeks
May 21, 2009 - Mill Creek - Muddy Bottom Method Sampling (Photos by Alana Hartman) |
| The clump of willows on river right are
the "x" spot of this sample, for future reference |
 |
| The orange flag
across the creek seems to indicate the channel at this stie should not
change location very much once the NSR is done. |
