Middle 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 Middle 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 Wind and Hood Rivers (exclusive) to and including the Yakima River; excludes such fish originating from the Snake River Basin. This DPS does include steelhead from seven artificial propagation programs: Touchet River Endemic Program, Yakima River Kelt Reconditioning Program (in Satus Creek, Toppenish Creek, Naches River, and Upper Yakima River), Umatilla River Program (Oregon Department of Fish and Wildlife (ODFW) Stock #91), and Deschutes River Program (ODFW Stock #66). This DPS does not include steelhead that are designated as part of an experimental population. Definition implemented by Columbia River DART: March 2010.
