I was told by a person that works for the corps of engineers that each lake has a projected pool level for every day of the year...Example lake X is suppose to start holding water March 15 and reach summer pool on May 1 under "perfect" conditions. If the lake is over targert pool they will discharge water until the lake is close to the target level for the particular day of the year.

If what I was told is true and the lake in question is over the projected pool level, then yes they will pull water below summer pool.
