Map of the Sacramento River and Sacramento-San Joaquin Delta showing location of acoustic telemetry receiving stations

Map of the Sacramento River and Sacramento–San Joaquin Delta showing the location of acoustic telemetry receiving stations (black circles) used to detect migrating acoustic tagged juvenile salmon from 2014 through 2018 as described in Hance et al. (2022). These telemetry stations divide the Delta into seventeen discrete reaches, shown as shaded regions labeled by sampling occasions in each migration route (01–10, A–E). Yolo Bypass (reaches 03B and 08B) is only accessible when the Fremont weir overtops, which only occurred in 2016, 2017, and 2018.
