5.0 SITE

The existing water control structures have concrete construction for the floor, walls, and bridges. The stop log risers were constructed in 2017 of stainless-steel channel. Engineering plans will be provided of the stainless-steel channels. The fabricated weir board sliding lift gates will be permanently fitted into one of the riser board sections after all wood boards are removed. Each water control structure sits below a section of cattleguard, which will be cut back and retrofitted around the weir sliding gate. Adjacent to the structures there are stainless-steel platforms for access to the water control structures.
