Assuming you have a standard setup, /var/hammer/$mountpoint/snap-YYYYMMDD-#### is the location of the snapshots. I don't know what the last four numbers are or mean for sure, but I assume it's HHMM. Either way, take whatever mount point, look for the snapshots in that directory, and du -sh it, that will provide you your answer. I don't know of a shorter way, but I suppose you could script something that iterates through directories in /var/hammer and then for a specific snapshot date and the takes a cumulative value of du from those items.
