Parachuting Beavers into Idaho's Wilderness? Yes, It Really Happened (2015) (opens in new tab)

Pioneered in Maine btw! The fish seem to do just fine[0][1]. At the end of video I've linked you'll notice they'll dump them out after landing if possible.[2]

>Department biologists using scuba gear have had trout dropped around them and observed as the fish hit the water and swam away. The biologists report that most of the trout easily survive their aerial drop without injury or harm.[0]

>The Aviation Division also supports the bureau's resource management efforts through aerial fish stocking and various data collection efforts. Aerial stocking is the least stressful method of delivering live trout and salmon to inaccessible or distant locations, Maine's Warden Pilots release more than 182,000 of them — over 28,000 lbs. — into 195+ lakes and ponds each year.[1]

We shall not forget the Cincinnati Turkey Tragedy...

Why beavers make dams is very interesting - they tend to instinctively build at the site of the sound (beavers are nearly blind) of running water. Canadian wildlife management has used this knowledge to trick beavers into not building dams where it would be inconvenient for highway management.
