Historical Harmonic Mean Travel Time Estimates
Adult Radiotelemetry Bonneville to Lower Granite Fall Chinook

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. Reach travel time is based on the last record at the top-of-ladder site (LT) at the first project and the first approach record (A1**) at the second project. 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 record at the top-of-ladder site (LT) for each Radio Telemetry 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.
