What is Aquatic Bioassessment?
Aquatic biological assessment (bioassessment) is the use of resident biota to determine the condition of aquatic resources. Information on this page concentrates primarily on the use of macroinvertebrate, periphyton and fish assemblages in rivers and streams, although many of the principles apply to wetland and lake ecosystems as well.
2009 Annual Meeting
The annual meeting will be held Nov. 4-6, 2009 in McCall, Idaho (a 2 hour drive from Boise) at the Shore Lodge (http://www.shorelodgemccall.com) . Registration begins at 12:30pm on Weds., Nov. 4th, the meeting starts promptly at 1:00pm. The meeting ends at noon on Fri. Nov. 6th.

Who are we - The Northwest Biological Assessment Workgroup
The purpose of the Northwest Biological Assessment Workgroup (NBAW) is to promote better understanding of the biotic communities in freshwater aquatic ecosystems of the northwest. The NBAW was founded in 1990. The NBAW encourages and facilitates the use of benthic macroinvertebrates and fish assemblages and other biota in the assessment of the condition of freshwater aquatic resources and other environmental and natural resource management decision-making. Membership is open to anyone who is interested in freshwater biotic communities and their role in aquatic ecosystems in the Northwest (generally, but not limited to: Alaska, British Columbia, Idaho, Oregon, Washington, and Northern California).
