A project that’s placing more of the right kind of gravel in the Sacramento River to provide salmon with spawning grounds will continue. The vast majority of spawning for Sacramento Valley Chinook occurs in the Redding area. A project began in January to place more than 21,000 tons of gravel in the river locally. The work started under the Market Street bridge. Now it’s moving upriver to a spawning area about a mile south of Keswick Dam near Salt Creek and Middle Creek Road along the Sacramento River Trail. Trail users should be cautious all next week as large gravel trucks will be crossing the trail at that location.
