Adult Upper Columbia River Steelhead DPS 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.

The Upper Columbia River Steelhead DPS includes naturally spawned anadromous O. mykiss (steelhead) originating below natural and manmade impassable barriers from the Columbia River and its tributaries upstream of the Yakima River to the U.S.-Canada border. Also, steelhead from six artificial propagation programs: Wenatchee River Program, Wells Hatchery Program (in the Methow and Okanogan Rivers), Winthrop National Fish Hatchery Program, Omak Creek Program, and Ringold Hatchery Program. Definition implemented by Columbia River DART: March 2010.
