Harbor Watch is led by Dick Harris, Director of Harbor Watch/River Watch, and Pete Fraboni, Associate Director and Senior Naturalist of Earthplace.  From May through September/October these men go out twice a week in the boat RV Annie, a refurbished oyster scow, along with a group of dedicated volunteers.  Some of the volunteers are high school students who help with Harbor Watch and River Watch and write up scientific analyses of the data observed.  Some high school teachers, including Jim Lucey from Wilton High School, have spent several years volunteering and encouraging their students to participate in the program.  There are also many adult volunteers who aid in the maintenance and care of the boat, help with the monitoring procedures, and with laboratory analyses.

Water samples taken from local streams, rivers and harbors are tested in the state-certified laboratory at Earthplace.

Dick Harris, Director of Harbor Watch/River Watch, and some volunteers showed local sea creatures to visitors at the 2004 Oyster Festival in Norwalk Harbor.
