What Moves You? Clear Creek Juvenile Salmon 24-hour Passage Timing Studies 2012-2013

U.S. Fish and Wildlife Service, Red Bluff FWO

Objectives

• Identify daily temporal passage

• Identify if particular environmental variables contribute to fish passage

• Determine if fish passage is proportionate to flow increases

• Utilize data to assist with passage interpolation when traps aren’t fished;

Methods • Sample RST every hour for 24-hour period,

every two weeks (where possible) during fall Chinook outmigration

• Measure environmental data at each sampling (i.e. flow, turbidity, barometric pressure, lunar phase, etc.)

• Year 1 - Sample 24-hours • Year 2 and 3- Target peak passage times to

confirm timing and possible migration cues and compare to spring Chinook emigration

What did we learn in 2012?

• Passage peaks daily in a three hour period from 1900 – 2200.

• 85 % of salmon are passing between 1900 – 0000.

• Daily distribution during 24-hour interval sampling, did not change throughout the season.

What did we learn in 2013?

• Passage peaks daily in a three hour period from 1900 – 2200.

• 77 % of salmon are passing between 1900 – 0000.

• Average passage timing was an hour earlier than 2012.

What did we learn in 2013?

• Barometric Pressure and flow changes do not seem to affect general timing.

• Both Chinook and Steelhead responded better to natural flow events versus artificial pulse flows.

Where do we go from here?

• Continue evaluation of environmental variables.

• Gather more data from flow events and determine if fish are holding during moderate or high flow events.

• Build time step model to more accurately project fish passage timing when traps aren’t fishing.
