John, certain lakes are on certain schedules do to recent rains, fluctuation levels, and other reasons. Cave Run was down three feet almost two weeks ago so it depends on where you are. Id say you can call the corp of engineers on that lake or the district office and they could tell you the specifics. I was curious to as to the schedule at which it occurs because I want to know which ramps will close due to water levels dropping. Hope this helps explain it some.
