Watershed management biologist Steve Rood with the Colorado State University helps conduct a fish survey at Swamp Pond on April 30, 2018, at Fort McCoy, Wis. The fish surveys, according to Fisheries Biologist John Noble with the Directorate of Public Works Environmental Division Natural Resources Branch, are necessary to determine the health of the installation’s many waterways. The surveys produce data that is critical for fisheries management. Surveys include electrofishing streams and netting and electrofishing lakes and ponds, Noble said. Much care is taken to ensure the fish caught are not harmed. Fish caught include rainbow, brook, and brown trout; bluegills; bass; pumpkinseed; crappies; and other warm-water species.
