Working on the basics for proposals to open up fish access to spawning/thermal refuge to tribs on a large river in PA. There are several tribs which have bridge structures (specially concrete box type culverts) which prevent fish passage. Most involve having created a plunge pool of 3'-4' lower then the bridge stream base.
Does anyone have any experience in remediation to allow fish passage, or know of where one can find specific information on this subject? Tons of info on fixing simple metal culvert type structures, but little dealing with concrete box types.
Any help or direction is greatly appreciated!
