Delta Discovery Voyage

2021-22 School Year Update

With safety as our guide but with the understanding that student learning is best achieved in person, the program format has changed this school year. The program will be held in person at the Big Break Regional Shoreline facilities in Oakley, instead of the typical format aboard the research vessel. Students will experience two outdoor educational stations and a single indoor station inside the interpretive center that closely mimic the stations the students typically experience aboard the boat—the goal is to maximize safety while preserving program effectiveness.

About the Delta Discovery Voyage

Students learn about the source of their drinking water through an expedition on a research vessel in the Sacramento-San Joaquin Delta. This interactive program features breakout sessions to cover various topics about life in the Delta and how we are connected to it.

This unique water education program is designed specifically for 5th grade classes and is available free of charge to schools in our  service area. The 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

Typically, this program is offered in person every year during January and February aboard a 90-foot research vessel, the R.V. Robert G. Brownlee, that launches from the Antioch Harbor. See photos of voyages from previous years to the right.
