How often is the Aquilla Lake water level updated?

What does percent full mean?
It is the water stored in the conservation pool divided by the conservation capacity (43,243 acre-feet for Aquilla Lake). Water above the conservation pool is flood storage and is not counted, so a reservoir can show 100% while rising into its flood pool.
