Bridge heights reported on Bizer's chart assume a full lake level of 4.3 feet. To calculate today's bridge clearance for any bridge on Lake Winnipesaukee, add 4.3 feet to the height shown on Bizer's chart. Then subtract the most recent lake surface-level reading to obtain the actual clearance of any bridge.

Today's surface reading is 4.38 (rounded to 4.4). The height reported on Bizer's chart is 4.2 feet. Therefore, the bridge clearance today is 4.1 feet (4.3 + 4.2 - 4.4)
