The bow is closed above the weir as of today. So u'll have to wait untill June 1st to fish it. Many good spots below the weir that are open to fish all year.
"Quote"If you want to go after whitefish try a royal coachman tipped with a maggot and a small slip shot about two feet up the line. Allow it to drift and bounce its way down river. If you find you are getting hung-up on bottom a lot you can add a small float (torpedo type work well) about 8 feet or so up the line.
Maggots are the only bait allowed on the bow and only from Aug 16th till Sept 30th.
hope this helps
