A minimum of 200 mm of depthshould be maintained. Depending upon the grade of the culvert and/or itslength, it may be necessary to construct a downstream step pool or installbaffles within the culvert to achieve the 200 mm minimum depththroughout the culvert.Culverts should be installed during low flow periods whenever possible.Where significant flow is present, generally acceptable techniques toisolate the construction site from stream flow include, but at not limited to,channel bypasses, temporary flumes, sheet pile or sandbag walls, waterfilled coffer dams, or pumping the stream flow around the work site.Accepted.
