Official Notice : Sturgeon Retention Closure in WA and OR

Sturgeon are key predators that maintain the balance of the Columbia River ecosystem.

The Impact of Sturgeon Retention Closure on the Columbia River Ecosystem

The closure of sturgeon retention in the Bonneville and the Dalles pools of the Columbia River and all adjacent tributaries has significant implications for the ecosystem. This decision was made to protect the endangered North American sturgeon, which is listed as threatened under the Endangered Species Act.

The Importance of Sturgeon in the Ecosystem

Sturgeon play a crucial role in maintaining the balance of the Columbia River ecosystem. They are apex predators that feed on smaller fish, crustaceans, and other invertebrates.

The John Day Pool: A Haven for White Sturgeon

The John Day Pool, located between the John Day Dam and McNary Dam on the Columbia River, has become a haven for white sturgeon.

The land was also used for various purposes, including farming, mining, and logging, before being set aside for national park status.

The History of National Parks

The concept of national parks dates back to the 1830s, when the United States government began to recognize the importance of preserving natural and cultural resources. The first national park, Yellowstone, was established in 1872, and it was followed by the establishment of Sequoia National Park in 1890. The National Park Service was created in 1916 to manage and protect these parks.

Early Years of National Park Management

The National Park Service was established to oversee the management of national parks, including the development of policies and regulations. The agency was responsible for protecting the natural and cultural resources within the parks, as well as providing recreational opportunities for visitors. The early years of national park management were marked by challenges, including the need to balance the protection of resources with the needs of local communities and the tourism industry.
