Rapid Assessment of Stream Quality


Objective
The objective is to evaluate the habitat quality of a small or medium sized stream by collecting information about the physical characteristics of the stream.

Equipment Checklist

General collection instructions
Volunteers visit practical access points (usually at a bridge where a road crosses the stream) and collect important information about the condition of the stream (e.g. stream width, water depth, substrate composition, water clarity, stream flow, bank vegetation, and land use). This is only possible in streams that are shallow enough to wade. Stream depth varies within the channel so always use caution when entering or crossing any stream. If the water is too deep mid-channel or if the current is too fast, simply indicate this on the data sheet. Always work with another person and wear a PFD (personal flotation device). If conditions preclude safe sampling, forgo that site!

Important Considerations, Miscellaneous Information and Field Hints

Conservation Issues and Ethics
Because many species of freshwater mussels are listed as threatened or endangered and it is illegal to possess such animals (dead or alive!), collecting recently dead or relic shell material is not recommended. Do not handle living mussels. While they appear to be hardy, they are sensitive to changes in environmental conditions. Even if an animal is returned to the water quickly, improper positioning can kill the mussel. Please do not handle living mussels!

Photo Documentation (optional)
Photo documentation of the stream is valuable for many reasons. The information captured in a picture may be helpful at a later date especially in long-term monitoring projects or when restoration work is in progress within the study stream. Also, it is sometimes helpful to take pictures of uncommon plants or animals for identification purposes since collecting is neither advised nor encouraged. Simply take a few pictures of the stream(s) and the surrounding area (as well as your self!) and send the photos with the completed data sheet. Record a brief description of the pictures taken and the picture numbers (from the camera) at each site on the data sheet in the Additional Notes section.

Data Quality Control
Volunteers are asked to adhere to the following procedures as part of data quality control.
1. In the field take duplicate measurements and double check the data by asking if the measurement "makes sense".
2. To maintain objectivity and minimize individual bias, alternate data collecting and recording responsibilities.
3. Lastly, before leaving a site, review the information on the data sheet for accuracy and completeness.
