Detailed Design of Avonlea Dam Riprap Upgrades

This RFQ for Engineering Services is for design and construction support services at the Avonlea Dam. The Avonlea Dam is an earthfill, embankment dam located approximately 60 km southeast of Moose Jaw, SK and about 1.6 km south and 3.2 km east of the Village of Avonlea, SK. The riprap at Avonlea has been the subject of recent engineering studies including a dam safety review (DSR). While there are no serious observable erosion issues with the riprap, the existing does not meet the industry standards for size and depth in many locations. WSA would like to remove some risks noted in the latest DSR by upgrading the riprap and making other improvements at Avonlea.
