Glad to be here!
It's not a big lake, so the typical size is on the smaller side depending on what area of the lake you fish, but in the 1.5lbs range is the average.
I don't bring a scale out with me, but the best I've done is maybe around 3.25-3.5lbs from there.
-edit- actually, after looking at some the photos on the site with estimated weights, the best I've pulled from the lake is closer to 4.5lbs.
I'm not very experienced at estimated weight so the figures could vary.
Here's a link to a shot of a decent crappie from the end of last summer. If you think of it in typical largemouth to crappie size for a lake, this is an above average crappie for the lake, maybe that will give you a sense of the average largemouth.
