Daily water temperature (C) in the Yolo Bypass and Sacramento River, 1998-2019

This data is an integration of raw logger data as well as relevant California Data
Exchange Center (CDEC) data (Pien et al. 2020, hourly) and water quality data collected during
the Yolo Bypass Fish Monitoring Program’s (YBFMP) fish collection (Pien and Kwan 2022) to
produce a daily water temperature dataset for the Yolo Bypass and Sacramento River at Sherwood
Harbor and Rio Vista Bridge. The raw YBFMP’s water temperature data was collected by loggers
attached to the rotary screw trap (STTD) and Sherwood Harbor (SHR). Logger data ranged from
daily means (1998) to a fifteen-minute collection interval (2013-2017 for the Yolo Bypass,
2009-2019 for Sherwood Harbor). A daily mean, maximum, minimum, standard deviation and
coefficient of variation in water temperature was produced as well as columns for sample size
(n, number of measurements per day), method (data collection or estimation), category, length
(number of consecutive missing dates) and site. Daily water temperature data for the full
extent of the YBFMP’s fish collection is valuable for a variety of purposes. For example,
variation in water temperature during inundation and comparisons between temperatures in the
Sacramento River and Yolo Bypass have been used as metrics of habitat complexity and linked to
life history diversity in salmon (Goertler et al. 2017).
