Because Delta smelt are now rarely being captured in regular CDFW fish surveys, the US Fish and Wildlife Service began the Enhanced Delta Smelt Monitoring Program (EDSM) in 2017. Results for the first four years show adult Delta smelt are still around in winter spawning season – barely (Figure 1). They continue to be found throughout the northern Delta and Suisun Bay/Marsh (Figure 2). Hotspots (likely spawning concentrations) were in west Delta near Rio Vista and the Deepwater Ship Channel. Juveniles continue to show up in EDSM summer surveys in the usual places (Figure 3). There may be a few thousand adult Delta smelt left as of 2019/2020 based on US Fish and Wildlife Service estimates.
