I can't believe this slipped through my radar. Many thanks to Jack Longacre for alerting me to it. He said the proposal would have flooded Mina Sauk Falls and cut off the trail that goes between Taum Sauk and Johnson Shut Ins.
A map of how close this would have been to Taum Sauk is available here:
This has been a huge issue all summer in Missouri.

Ameren drops plans for plant in the Ozarks
By William Allen
Citing public opposition, Ameren Corp. on Wednesday pulled out of its plan to build a hydroelectric power plant and two dams on Church Mountain in the Ozarks.
The company's announcement came shortly after Missouri Gov. Bob Holden and other state officials attacked the plan.
Attorney General Jay Nixon asked the Federal Energy Regulatory Commission on Wednesday to deny the company's preliminary permit application to build the $642 million hydro plant. Among other complaints, Nixon said the project would flood state property.
"We are opposed to blowing off the top of Church Mountain and replacing it with a limestone bathtub," Nixon said in a telephone interview shortly after filing the motion.
The new plant would have produced 770 megawatts of electricity using the pressure of falling water during times of peak electrical demand. The water would be pumped back up to the reservoir at times of low demand. The Church Mountain plant would have been Ameren's biggest hydroelectric facility - producing even more power than the 440 megawatts now produced by Ameren's highest-capacity hydro station atop nearby Proffit Mountain.
In the motion filed Wednesday, Nixon said the project would flood land in Taum Sauk Mountain State Park and hurt "the scenic splendor of the region." It would also lead to "loss of habitat for an endangered species, total destruction of a mountaintop and the damming of a waterway" - Taum Sauk Creek - "which has been designated under state law as an 'outstanding state resource water.'
