How often is the Lake Athens water level updated?

What does percent full mean?
It is the water stored in the conservation pool divided by the conservation capacity (29,503 acre-feet for Lake Athens). Water above the conservation pool is flood storage and is not counted, so a reservoir can show 100% while rising into its flood pool.
