Materials:
Setting up site
Identify the riffles and pools in the site (Pools are seen in a winding stream where the outer edge of each loop is deep and uppercut; riffles form in the shallow water of the short, straight, wide reaches between adjacent loops)
measure 40m upstream from a downstream crossover make sure there is a point in the stream where the current travels parallel with the banks
Mark the transects
- waste bucket
- sample bucket
- one 500 micron sieve
- squirt bottles

Collecting your sample
Collect sample from all transects, use the Traveling Kick Method to collect samples
Collect sample from all transects, use the Traveling Kick Method to collect samples
- hold d- net facing upstream so stream flows into net
- with d net on stream other person will "kick and dance" in front of net
- work your way across the transect
- Pick-up rocks sub their surface to dislodge any bugs and collect them in the net
- take the sample that you have just collected and put it in a 500 micron sieve
- using the squirt bottle wash off all the dirt and mud into the waste bucket
- after washing the 500 micron sieve but the remaining sample into the sample bucket
