With the rain we had over the weekend and the rain predicted this week, I would be surprised if we break 504.32 by Saturday. That's always listed as the normal high, but if you look at Bizer's chart the lake exceeds that very often. If you look at the state chart, the upper bound of the standard deviation for this time of year is above 504.5 maybe 504.6 or even 504.7. That's reachable by Saturday. Looks like we are at 504.86 right now.
