Bonneville HatcherySturgeon range throughout the Columbia River system, however the construction of Bonneville Dam and the other dams upstream blocked sturgeon migration. Sturgeon, unlike salmon, do not use fish ladders. Sturgeon below Bonneville Dam travel up and down the Columbia and even out into the ocean, often entering other coastal bays and rivers. Sturgeon migration depends on availability of food and spawning cycles. Sturgeon need fast, flowing water of moderate temperature over rocky bottoms for spawning success. An ideal spawning area is located just several miles below Bonneville Dam.
