A culvert has an attachment at an entrance end for inhibiting beaver activity at the culvert where the attachment includes two panels coupled together at one end by a third panel portion or by a hinge to form a pivotal structure with each panel including a bottom rail placed on a ground surface extending from the culvert entrance and a plurality of upstanding bars at spaced positions along the bottom rail. The attachment is opened at the hinge line or the third panel portion so that the hinge line is located in front of the entrance with each panel extending back to a respective side of the entrance and fastened by a chain coupling to that side. The upstanding bars are arranged so that water passes therebetween to or from the entrance end and the bars are closely spaced so as to prevent passage of beavers to the entrance end.
