Sampling Protocol

• You will need four sampling containers. They can be either glass or plastic, although glass is better, but most importantly, make sure they are clean. If you do not have your own, there are jars/bottles available in the lab at the Green Drake.
• Bring along one recording sheet for each reach (the ones Charlie made, not the spreadsheets) and fill in the appropriate information while you are in the field.
• You will collect four samples at each reach at equal distances along its length: in other words, we are dividing the reaches into quadrants. To do this, start at the bottom of the reach (Q4) and pace out approximate quadrants. Collect samples from the downstream end of Q1, Q2, Q3, and Q4 (the bottom of the reach). You should not have a sample from the top of the reach.
• Take samples from the channelized part of the stream (roughly the middle third of its width) as opposed to the very edges.
• Dissolved Oxygen is the only test that should be done in the field. All others should be done in the office/lab at the Green Drake.
• Record your results on the recording sheets.
• Use distilled water to thoroughly clean test equipment following completion.
