Sampling

See protocol document for additional information: StreamWatch_Protocol.pdf. Field equipment: Thermometer(in Fahrenheit), Turbidity tube, Forest densitometer, Sample containers, Measuring tape/yardstick(centimeters), Wading apparel (rubber boots/waders), Isopropyl alcohol 90%, Kicknet, 2 Buckets, White enamel pan, Decontamination kit (spray bottle containing 5% bleach solution, to be refreshed monthly), Ice cube trays, Paint brushes, Dissolved oxygen meter (To be used only by DSRC staff), Magnifying glass, Weighted line (For streams deeper than 1 meter), Lab equipment, pH meter. PRECAUTIONS: StreamWatch volunteers must collect data in pairs for safety. Consider wearing water-resistant clothing and footwear, or a personal flotation device if streams seem too vigorous or deep, and stay hydrated in hot temperatures. Know when not to wade; if the current is even remotely strong, use caution or skip wading. When wading is a possibility, your monitoring partner should be close by and aware. Consider weather conditions and be aware of approaching bad weather. Be cautious walking on streambanks, causing erosion will damage the ecosystem and could result in unstable footing. Follow the instructions step-by step, ideally read through instructions before you reach the site. Avoid excessive contact between hands and, eyes, nose, or mouth after touching sample materials. Use all equipment responsibly to ensure further use. Some stream locations require longer hikes to get to, while others are directly accessible by car; use good judgment in considering how far you can comfortably hike. DECONTAMINATING WADERS: Remove all mud, organic matter, etc. from boots/waders. Prepare 5% fresh bleach mixture in spray bottle and spray thoroughly. Dry thoroughly. Alternatively, leaving boots/waders in freezing temperatures overnight has same effect. This prevents the spread of invasive microorganisms which can lead to overgrowth and spread of freshwater invasive species to different streams.
