Snake River Chinook Spring/Summer ESU Historical and Current Year Mean Travel Time Estimates
Click on a reach travel time in the table to view a plot of the reach-specific daily mean travel time as it varies throughout the season. The date of the daily mean travel time is determined by and plotted on the reach entry date, i.e., the date of the last detection for each PIT-tagged fish at the first project in the reach. The plots include a 95% confidence interval for each reach entry date on which more than one fish started traversing the reach.
