Our mission is to create a better future for the San Diego River through volunteerism, advocacy, education, and championing the creation of a river-long park system.We are a San Diego based 501c3 nonprofit that started as an all volunteer group and remain grounded in engaging people through volunteerism. Before the pandemic, we engaged more than 7000 volunteers. We believe in targeting our programs to make a meaningful impact for the river, its ecosystem and San Diego. Our mission is to work toward a day where nature and people live in synergy. A world where being outdoors in nature is accessible and valued. A place that works to conserve our vanishing species and values their intrinsic beauty. A place where we find wonder and awe in nature and integrate it our daily lives.

Save the Bay™, and keep it saved, as defined by reaching a 70 on CBF's Health Index. The Chesapeake Bay Foundation's (CBF) mission, simply stated, is to Save the Bay and keep it saved. We define a Saved Bay as having a score of 70 (out of 100) on CBF's State of the Bay health index. Thanks largely to a dramatic reduction in the amount of pollution entering the system, at 70, the Chesapeake Bay and its tributary rivers will be highly productive and in good health as measured by established water-quality standards. The result will be clear water, free of impacts from toxic contaminants, and healthy oxygen levels, able to support living resources in all parts of the Bay.
