What's worth doing
Things to do
Why does the Navy test submarines at Lake Pend Oreille?
The lake's 1,150-foot depth and quiet water — free of the ocean noise that complicates open-water testing — make it ideal for acoustic research. The Navy's Acoustic Research Detachment at Bayview has tested submarine and surface-ship acoustics here since the 1960s, and Idaho's own small submarine fleet, dating to the 1940s Farragut Naval Training Station, still operates on the lake.
On the water & on the trail

Where can I rent a boat at Lake Pend Oreille?
Bottle Bay Resort & Marina in Sagle and Action Water Sports in downtown Sandpoint both cover boat and watercraft rentals. Dover Bay Marina, a 274-slip deep-water marina west of Sandpoint, covers moorage and launch access.
Is Lake Pend Oreille related to Coeur d'Alene Lake?
Yes — both lakes share the same ice-age origin, carved by the Missoula Floods when the Purcell Lobe of the Cordilleran Ice Sheet repeatedly dammed and released the Clark Fork River roughly 12,000 to 15,000 years ago.
