Exit the building and jump into the water, then dive down into the submerged building and free the wooden plank from the roof.

How To Clear The Hydroelectric Dam Ambush

Before approaching them, make sure you’ve upgraded your Melee Weapon and craft some Melee Kits, then slowly work your way through the area whilst picking off any bandits in the distance with the Hunting Rifle and the closer enemies with a Shotgun.
