For eight weeks starting January 9, more than 4,000 students from across our service area will climb aboard the 90-foot research vessel Robert G. Brownlee. They’ll chart a course up the Sacramento-San Joaquin River Delta for a half-day adventure to learn about the primary source of their drinking water. The ship is owned and operated by the Marine Science Institute of Redwood City. Contra Costa Water District sponsors the voyages along with Central Contra Costa Sanitary District, Delta Diablo, Dean & Margaret Lesher Foundation, Mt. View Sanitary District, Golden State Water Company and Dow Chemical Company.
