The Springfield News-Leader ran an intriguing article on paddlefish going over dams and surviving. Sadly, it didn’t mention that most are killed whether they go through the turbines or over the top in a flood. It’s common to see pieces of paddlefish below dams after they were sucked into turbines and chewed up. Our guess is one out of hundreds survive.
But it’s heartening to know that this incredible, giant prehistoric fish occasionally gets lucky. Corps of Engineers’ dams have contributed to their conceivably endangered future. While the adults thrive in reservoir pools, damming blocks access to their spawning grounds.
In our book, Damming the Osage: The Conflicted Story of Lake of the Ozarks and Truman Reservoir, the fate of the paddlefish occupies many pages. Truman Dam destroyed the best spawning grounds in the country. All the paddlefish in Missouri are hatchery-spawned and raised. We quoted a publication by the American Fisheries Society entitled, “The Paddlefish: Status, Management and Propagation” (1986):
Finally, a note of caution. Although techniques for producing and stocking paddlefish were presented in this symposium, we do not consider stocking to be an answer to habitat deterioration and management problems. These techniques were developed for special circumstances where stocking was the only way to maintain a population. Artificial propagation and stocking should not be used as a cure-all or substitute for wise or practical management. Trying to solve problems by treating symptoms is expensive and ineffective. In addition, stocking would affect the integrity of paddlefish gene pools and is ill-advised until we know a lot more about the genetics of this species.
The MICRA paddlefish-sturgeon committee issued a warning in 1998 that “the use of hatcheries to reduce population declines is not a substitute for solving the causes of declines.” In addition to genetic considerations, the paper listed six other problems with stocking,hatche of which “delaying habitat restoration” was the worst.

The Department of Conservation fisheries people are to be praised for keeping the paddlefish from vanishing from Missouri waters. It’s an expensive program and should there be a severe recession raising paddlefish might be defunded. MDC gets most of its money from a conservation sales tax. This largely bypasses political control. Some politicians wish to do away with this arrangement. It’s likely, should the state legislature control the MDC budget, urban interests might not be favorably disposed to maintaining the paddlefish-raising program. Paddlefish might be seen as expendable.
The fate of the paddlefish (or spoonbill) was central to a lawsuit to stop Truman Dam—which obviously failed. Our 304-page book, Damming the Osage, is available on amazon.com or this website at a discount, postage paid
