“Rockwads” Project
Improving Rearing Habitat for Juvenile Salmon and Steelhead Trout
To address lack of natural rearing habitat in the upper reaches of the Sacramento River, 25 natural ‘rockwad’ structures - which are made of almond tree canopies and large boulders - will be installed from April 27 to May 3, 2026.
The ‘rockwads’ are intended to help provide juvenile salmon and trout refuge against larger predators as well as opportunities to feed which aims to entice them to stay in colder waters longer, thus increasing their odds of healthy maturation for their journey to the Pacific Ocean.
Hear From Project Leaders:
“The diverse makeup of the ‘rockwads’ - with the boulder and woody debris - create an ideal setting for foraging, cover, and rest for the small juvenile salmon and trout,” said Roger Cornwell, President of SAVER. “With less debris naturally entering the upper portions of the Sacramento River, we must provide opportunities that these young fish historically found during their outward migration.”
“Placing the structures in this specific section of the river pairs with key times in the juvenile salmon’s early rearing and migratory passage along the Sacramento River,” said Jeff Souza, Biologist with Tehama Environmental Solutions. “We hope the addition of more structures will ultimately mean more salmon fry will grow to a healthier, robust size so they can better overcome challenges downstream.”
