Abstract

The velocity of water in a stream affects vegetative growth, nutrient dispersal, temperature, as well as rearing habitat and spawning areas for salmon and steelhead. We measured stream velocities and depth at 20 locations along a 1.8 km section of the Reecer Creek Floodplain Restoration Project, Ellensburg, WA. We compared our data to fall of 2014. We found that the stream velocities in fall of 2021 had a lower average velocity (0.527m/s < 0.748m/s) and lower standard deviation [0.259m/s < 0.362m/s]. For the 2014 data set 27% of data points were outside of one standard deviation compared to 40% of our data points more than one standard deviation away. From this, we were able to conclude that the restoration was successful in creating a variable stream habitat that is favorable to a healthy salmon and steelhead population.
