Summary Despite growing interest and investment in salt‐marsh restoration, relatively few marshes subjected to restoration efforts have been systematically monitored assess physical trajectory or success. In south San Francisco Bay, California, USA, where 83% of wetlands were lost via human manipulation, the largest wetland effort on US west coast is currently underway, restoring approximately 6000 ha former salt‐production ponds mixed habitats. The Whale Tail–Cargill Mitigation complex Bay has a century‐long history drainage, industrial use as subsequent recovery. Restoration 20 Cargill Marsh was initiated late 1990s when levee surrounding subsided, pond breached two locations, enabling conversion back habitat decades. Here, we present time‐series measurements sediment fluxes primary tidal creek entering complex, which are compared decadal‐scale sedimentation patterns determined from repeat elevation surveys cores collected at study site. All three methods show net import restored marsh. greatest equivalent rates occurred early with generally decreasing through time. long‐term average, expressed vertical rate, 1.8 cm year −1 . Rates data between 1.4 2.6 , higher earlier restoration. most recent estimates, computed instrument deployments, indicate seasonal variability import. Annualized lower winter, 0.1 summer, 1.7 Although our measured considerably greater than current local relative sea‐level rise (SLR) 0.3 an increase SLR decrease available suspended would threaten ability marsh keep pace avoid drowning future.
