What Month does Barren River Lake go back up to summer pool?

What Month does Barren River Lake go back up to summer pool? and around what day?

I think they usually start holding water around the 15th of April.

Accordding to the Corps of Engineer site, they start holding water on March 15th and it should be at summer pool by April 15th. Of course, that all depends on how much or how little rain we get.
