On December 18th, 2008, the Stockton Fish & Wildlife Office’s Delta Juvenile Fish Monitoring Program (DJFMP) took delivery of a 42’ East Coast Style Lobster Trawler.  The boat was built by Millennium Marine of New Brunswick, Canada.  This purchase marks the end of a 2 year process and is a direct result of the Interagency Ecological Program IEP vessel replacement program.  Funding was made possible by the U.S. Bureau of Reclamation. 

The new vessel, named R/V Confluence has replaced the same style trawler ‘Leslie E. Whitesel’ which has been conducting midwater trawls at Chipps Island since 1985. The Whitesel will continue to be available for comparative trawling during this upcoming field season, anytime during the Confluence servicing, plus any additional requests for use by the Department of Fish and Game or other Service partners.

The Confluence is powered by a 610 hp, Cummins QSM11 series Diesel engine, and has a cruising speed of over 18 knots.  The wheelhouse has a main helm with a full suite of hydraulic controls, bow thruster, galley, head, and bunks. The deck is equipped with two hydraulic level-wind winches, a U-frame gantry system with davits, and two more steering stations, with hydraulic controls at each station.

With its low-to-the-water design, and beam of over 15 feet, the Confluence is a comfortable platform for trawling even in rough conditions. The vessel is able to perform midwater, kodiak, and bottom trawls, along with tow net surveys, and water quality measurements.
