The Garrison Dam National Fish Hatchery in North Dakota is currently lining more of its ponds. The expansive site has had a mix of lined and unlined ponds, and over time hatchery personnel have reported significantly higher, healthier yields with lined ponds. When federal funds became available for improving the facility, which is an important link to fish supplies in the Midwest, the hatchery capitalized on the opportunity. Installation work is going on right now.
