A fish biologist's work is never done!
U.S. Army Corps of Engineers, Seattle District, Fish Biologist Chuck Ebel scraps barnacles around a filling tunnel during annual maintenance at the Hiram M. Chittenden Locks in Seattle Nov. 13. The Locks two massive filling culverts, nearly 14 feet tall by 8 feet wide and about 800 feet long, are scraped by hand to remove barnacles that could injure juvenile salmon during migration season. Ebel is the biologist who recommended the barnacle scraping to help protect salmon. It takes Corps employee volunteers about four days to complete the scraping. The large lock chamber closes each November for annual maintenance and inspection. (U.S. Army Corps of Engineers photo by Bill Dowell)
