Here is a link to the WDFW "Operating Protocols and Guidelines for Advisory Groups". Depending on the group, a chair may be elected and the group then sets its agenda.

The Open Public Meetings Act (RCW 42.30) provides the sideboards for the meetings http://apps.leg.wa.gov/rcw/default.aspx?cite=42.30

The WDFW staff coordinator "....will assist each advisory group in understanding whether the OMPA applies as a matter of law. Nevertheless, the Department encourages...advisory groups...to conduct their business in an open, transparent manner, consistent with the intent of the act."
