Saskatchewan Ministry of Highways and Infrastructure's realignment and widening of Highway No. 219 resulted in the loss of a portion of Beaver Creek. An aging timber bridge was removed during the construction. The bridge was replaced by one 5.23 m diameter, 47 m long structural plate culvert, plus one 0.8 m diameter, 66 m long corrugated steel pipe culvert. Fisheries and Oceans Canada (DFO) authorized the harmful alteration, disruption or destruction (HADD) of fish habitat for the bridge-to-culvert project and required several mitigation measures during construction, compensation for the HADD, and three years of post-construction monitoring. This submission of this paper documents an innovative and creative approach to fish habitat compensation for a bridge-to-culvert project. The following pages highlight the key features of the compensation efforts and demonstrate the relationship between riparian habitat compensation and fish habitat compensation.
