Delta Discovery Voyage

Climb aboard a 90-foot research vessel, the R.V. Robert G. Brownlee, for a four-hour expedition of the Sacramento-San Joaquin Delta to discover the life in the Delta and how we are connected to it.

Program Details

The main goal of the program is to teach students about the source of their drinking water. Students rotate through 3 or 4 stations using scientific methods and equipment to conduct various experiments to understand water quality and examine different types of life.

This program is sponsored by local water and wastewater agencies including us (Contra Costa Water District), Central Contra Costa Sanitary District, Delta Diablo and the Mt. View Sanitary District. This program is presented by Marine Science Institute. They offer in-classroom resources to support the lessons learned on the voyage.


This program is available for schools in our service area. Programs are designed specifically for 5th grade classes and are offered every year during January and February. The research vessel launches from the Antioch Harbor.
