SMALL STREAM FISH LADDER
A fish ladder for small-bodied fishes that is easily portable so as to enable installation and use in a given water course when needed, and relocation at other times. The fish ladder defines a channel with generally evenly spaced baffles in the channel disposed at about 45° angles to the channel bottom. The ladder includes a bracket that enables the ladder to be attached to any size, shape, and material of culvert or other drainage structure. The ladder is attached to the bracket with a hinge mechanism, so as to accommodate virtually any height of drop presented by small drainage structures. With extendable legs, a fish ladder according to embodiments of the invention is able to be installed in streams up to 6 feet deep. The ladder can be scaled so as to target passage of small-bodied non-game species such as minnows, while also passing larger game species as well.
