#AmericanRivers and #Riverkeepers celebrate the removal of a rusty, abandoned dam on Wynants Kill near Albany, NY. Already they see the flash of silver as herring swarm upstream to spawn.
” ‘Every dam should have an existential crisis,’ ” said John Waldman, a biology professor at Queens College, tells The Associated Press.” In Missouri, time for that crisis has come for one of those aging, inoperable and dangerous structures. We have an extensive discussion of the issues surrounding Lock and Dam No. 1, a monstrous relic, more than 100 years old, of Corps of Engineers river mismanagement on our website: (click here) Lock and Dam no. 1 on the Osage River.
This was taken during the 2012 drought. The river is full now and its waters barely cover the tops of the crumbling old concrete, barely held together with rusting iron and rotten wood. More than 100 years old now, Lock and Dam No. 1 serves no useful purpose for navigation or flood control, and it blocks the migration of paddlefish and endangered pallid sturgeon.
Removing Lock and Dam No. 1 would open those 80 miles of Osage River from Bagnell Dam to its junction with the Missouri River to possible spawning of both paddlefish and the endangered pallid sturgeon. Major spawning grounds of the paddlefish were destroyed by construction of Truman Dam. Per Wikipedia, the endangered pallid sturgeon, related to the sturgeon, another ancient fish (Cretaceous period), is endemic to the waters of the Missouri River system and the lower Mississippi. Like the paddlefish, its spawning grounds have been greatly diminished by river channelization and dams. Both species are now sustained by hatcheries. The gravel bars of that last section of the wide, slow Osage River could provide both species an environment for natural spawning.
