I started going to Powell in 1971. I was there in 1980 when it was filled. I was there in 1983 when they over filler it. It has been dropping ever since. I was there last year. Here is a shot of the Bullfrog boat ramp. This ramp is over 1/4 mile long. As of right now no boats in or out of the water.
The Colorado River goes through my town and I don't think Powell or Mead will ever be full again.
In the 2nd pic you can see where the water should be.
