A team of aquatic biologists descended into Napa Creek on Thursday to remove fish from an area of planned flood control construction. Using a long wand and a battery pack, a worker stunned the fish with a mild electrical charge, then scooped them up.
As of Friday morning, approximately 1,800 fish had been relocated upstream. Except for a bucket of crawfish, which were deposited downstream, all were native to the Napa River watershed, said Julie Lucido, project manager with the Napa County Flood Control District.
Captured fish included about 1,000 three-spine sticklebacks, 500 California roach, 150 Sacramento suckers and 100 steelhead.
Once the “de-fishing” is done, the creek between Behrens and Coombs streets near downtown Napa will be put into a pipe so that flood control work can begin, flood workers said.
Between now and October, the federal contractor, Proven Management Inc., will be removing the Coombs Street bridge, terracing the north bank between Coombs and Seminary streets, and completing a flood bypass culvert between Behrens and Seminary.
By year’s end, defenses should be in place to protect the Napa Creek neighborhood from winter floods.
The creek project is part of the larger Napa River flood control project run by the Army Corps of Engineers.
