Bonneville Fish Hatchery

Bonneville Fish Hatchery is a working fish hatchery with public ponds and a sturgeon viewing center on the Columbia River near Cascade Locks. It is one of Oregon’s major fish-production sites, but the visitor draw is its live displays, especially Herman, a white sturgeon about 10 feet long. You can look down into his pond, then step into a covered kiosk to see him through a large underwater window. For a short, fish-focused stop, this is one of the Gorge’s better detours.

Begin at the Sturgeon Viewing Center, then follow the paved path partway around Herman’s pond to an outdoor viewing platform. A nearby outdoor pond holds young sturgeon. Two other display ponds have rainbow trout brought in for visitors to feed; the trout aren’t raised here. Feeding gives the visit a hands-on moment. Trout can bite, so don’t touch or tease them. Interpretive displays and a short video explain the fish and the hatchery’s work.

The facility dates to 1909. It was expanded in 1957 as part of a program to improve Columbia Basin fish runs, then renovated in 1974 to mitigate fish losses tied to John Day Dam. Today it raises Chinook and coho salmon and steelhead. The sturgeon in the famous viewing role has changed over time: several individual fish have been known as Herman. The current Sturgeon Viewing Center opened in 1998, giving the fish a dedicated home on the hatchery grounds.

Use 70543 NE Herman Loop in Cascade Locks and take I-84 exit 40. The hatchery campus is separate from the Bonneville Dam visitor center on Bradford Island, so don’t mistake one attraction for the other. Fall brings adult Chinook and coho into the outdoor ponds for spawning. The trout display ponds are a year-round draw. You’ll find picnic tables, accessible restrooms, interpretive displays, parking, and a year-round gift shop. The viewing center is accessible, and the path around the sturgeon pond is paved for part of the way.
