The model run failed. Details of the error have been logged.

There are no public scenarios to display for the current water year.
A new scenario for this water year can be created by copying a scenario from a previous water year and changing the decision date to this water year.
Note: October 1st will become a selectable decision date once real-time data for that date becomes available on the morning of October 2nd.

¹ Maximum flows are used to determine mortality due to scour; minimum flows are used to determine mortality due to desiccation.

² Rearing mortality is based on temperatures and density-dependent interactions.
