Level 2 WAV Stream Monitoring
Initially piloted in 2006, this level of the Water Action Volunteer program brings volunteers to the next step in stream monitoring. At this level, citizens are trained to use Department of Natural Resources’ methods for monitoring streams. Dissolved oxygen, pH and transparency are monitored monthly between April and October on pre-determined dates. Continuous temperature monitoring devices, called thermistors (e.g., HOBOs or TidBits) are placed in the stream and record temperature every hour until they are removed from the stream and data are downloaded to a computer. Meters for monitoring pH and dissolved oxygen must be calibrated by the citizen monitors on each sampling day. Due to the high cost of equipment for this level of monitoring, citizen groups share equipment, thus providing as much data as possible in a given area.
