Safety is paramount here; no mallard is worth drowning for. And besides, the rising water will likely have displaced any ducks you’ve previously scouted. That said, it’s cruising time, but preferably after sunup when you can see obstacles. Gas up the boat and start looking. Quiet backwaters, secluded eddies, inundated standing timber, and newly flooded acres all hold potential; however, you need time spent at the tiller to find such spots. Face it—opening day just became scouting day, but it may be worth it when you discover 200 mallards paddling through a knee-deep field of foxtail.
