Rotary Screw Trap Open House

Want to get up close and personal with our salmon and steelhead?

Join us at the RCD’s rotary screw trap, an 8-foot rotating fish trap located in the Napa River to catch, measure, and release fish in order to generate population estimates and collect genetic samples. Come and see the day’s catch! RSVP to
