Your tax dollars at work.
Prior to the building of the Glen Canyon Dam, the humpback chub lived throughout the Colorado River system in Arizona and Utah. However the dam, among other things, destroyed the habitat of the chub and it was added to the endangered species list in 1967. So the Bureau of Reclamation has been creating artificial floods to restore the habitat and the endangered minnow. Only one problem, the increased flows resulted in an 800% increase in rainbow trout populations who like to feed on...wait for it..... humpback chub. So now the Bureau of Reclamation is again proposing to kill thousands of trout using electroshock, perhaps annually for up to a decade, and at a cost of millions of dollars to taxpayers, to protect the chub.
To top it all off researchers aren't even sure that removing the trout, as they did between 2003 and 2006, will do much good.
FYI....the Feds don't electroshock the 15 miles of tailwater below the dam that encompasses Lees Ferry.
