Summary of February-May Delta Smelt-relevant temperature metrics comparing the Yolo Bypass Toe Drain, lower Sacramento River near the city of Rio Vista, and the confluence between Sacramento and San Joaquin Rivers (Sac-SJR confluence) for the duration of the study period.

Values shown are mean temperature from February to May for each year, the number of spawning days available for Delta Smelt for each period based on temperature (15–20°C), and the median day of year for each spawning period (where January 1st = 1).
