A lock permit is required for all watercraft using the lock. To reduce the spread of coronavirus, all Tenney Lock permits must be purchased online. There are currently no in-person permit sales at the locks so please plan ahead. A daily or annual permit must be shown to the lock attendant (printed or displayed on your device).
A permit will be required for each watercraft to travel up river from Lake Monona to Lake Mendota. Due to congestion above the Lock, a permit will not be required to travel down river from Lake Mendota to Lake Monona.
Opening day is Thursday, April 28th.
