Yuba Gravel Placement

The U.S. Army Corps of Engineers (USACE) Sacramento District is seeking quotes for the annual placement of up to 5,000 short tons of triple-washed spawning gravel into the upper Narrows reach of the Lower Yuba River. Located near Smartsville, California, the project aims to restore geomorphic processes and aquatic habitats for Central Valley spring-run Chinook salmon and steelhead. This procurement is a 100% Small Business Set-Aside under solicitation W9123826QA014, featuring a base year and four option years. A major operational requirement is the strict seasonal window for gravel placement, which must occur between July 15 and September 1 each year. The technical approach requires a sluicing injection method using specialized equipment, such as 8-inch flexible piping and vegetable-based hydraulic fluids, as detailed in the Performance Work Statement and the Gravel/Cobble Augmentation Implementation Plan. The Yuba Gravel Placement project is a habitat restoration effort by the USACE Sacramento District. It focuses on adding spawning gravel and cobble to the upper Narrows reach of the Lower Yuba River to support Chinook salmon and steelhead populations. The project involves rehabilitating aquatic habitats in the Englebright Dam reach of the Lower Yuba River by adding a specific mix of triple-washed gravel and cobble. This effort supports the spawning and incubation of Chinook salmon and steelhead in compliance with National Marine Fisheries Service biological opinions.
