This dive site is an advanced drift dive located in the Columbia River Canyon. Divers navigate through the canyon, experiencing moderate visibility and often dark conditions, necessitating a powerful dive light. The dive begins upstream, progressing with the river's strong current, and the exit is near the base of the 182 bridge. As a major river system, the site's history is tied to the geological formation of the canyon and its long-standing use as a waterway and source of life.
The canyon is home to notable freshwater species. In the deeper sections, channel catfish and juvenile white sturgeon are commonly observed, while the shallower areas may reveal bass, shad, walleye, and carp. The description does not mention specific aquatic plants or other macro life.
The best time to visit for diving is not specified, but appropriate cold water gear (like a drysuit) is essential for this Pacific Northwest river. Divers must maintain extreme vigilance for boat traffic near the marina, which poses a significant hazard, especially with limited visibility. Due to the challenging conditions, this site is exclusively for experienced divers comfortable with strong currents and low visibility.
