Activities include spearfishing in Lake Oahe and drift diving in the tailrace below the dam. Imagine shooting your limit of walleye above on the Lake, then exploring for ancient buffalo bones and lost lures while observing prehistoric sturgeon and playful small-mouth bass in their natural habitat during an invigorating tailrace dive. Other fish include burbot, trout, and white bass among several other beautiful species. Come visit Pierre and Skin & Scuba Oahe for your next diving adventure!
