The goal of this study is to develop a high level overview of the physical and ecological changes to lower San Francisquito Creek and the surrounding tidal marshes and mudflats (referred to here as “baylands”) since the beginning of intensive European-American settlement. Building upon a previous reconnaissance-level historical ecology study (Hermstad et al. 2009), this study analyzes the changes in key landscape features (or landscape metrics) within lower San Francisquito Creek and baylands through comparisons of reconstructed historical (mid-1800s) and contemporary (2011/2012) conditions. The results from this study are intended to provide baseline information that can be used to help with developing restoration and flood control redesign alternatives and appropriate habitat restoration targets. This study is one component of the Flood Control 2.0 project, a regional effort funded by the U.S. EPA to help design flood control channels at the Bay interface that support tidal habitats while maintaining the required level of flood protection. Emerging strategies for flood protection focus on reconnecting channels to floodplains and tidal marshes and using available dredged sediment as a resource to increase marsh elevations and help keep pace with sea level rise. Lower San Francisquito Creek is one of three implementation projects that have partnered with Flood Control 2.0 to assess the benefits of an integrated approach for flood control and habitat management at the Bay interface.

San Joaquin Basin Flood‑MAR Watershed Studies Basin-wide Summary and Next Steps

California Department of Water Resources (DWR) | December 3rd, 2025

The San Joaquin Basin Flood‑MAR Watershed Studies (Watershed Studies) — comprising five watershed reports for Calaveras, Stanislaus, Tuolumne, Merced and Upper San Jo

The San Joaquin Basin Flood‑MAR Watershed Studies (Watershed Studies) — comprising five watershed reports for Calaveras, Stanislaus, Tuolumne, Merced and Upper San Joaquin watersheds and a Basinwide Summary — deliver data-driven assessments of climate change vulnerabilities and adaptation that reveal risks and consequences and call for bold, coordinated solutions. In the San Joaquin Basin, the effects of climate change will exacerbate long-standing water management challenges. As these reports quantify, every water management sector — flood, water supply (surface and groundwater), and ecosystems — is vulnerable. Without bold action, the basin and its watersheds face mounting threats to communities, economies, and ecosystems. Although each watershed has unique characteristics, all confront a future climate that is hotter and characterized by more extreme weather. For flood management, the 2022 Central Valley Flood Protection Plan states clearly: Catastrophic flooding in the San Joaquin Basin is not a question of if, but when. Meanwhile, the reliability of water supplies is expected to worsen, and ecosystems face degradation.  Click here for the California Department of Water Resources Watershed Studies home page
