RECLAMATION OF CANMORE CREEK: EXAMPLE OF A SUCCESSFUL WALK AWAY PIT LAKE CLOSURE
Stephenson, H.G. and D. Castendyk.

The mining of semi-anthracite coal in the Bow River valley began in 1886 and continued until the Canmore Mines Ltd. closed in 1979. This article discusses Canmore Creek Mine pit lakes' reclamation into sustainable, post-closure resources that are highly valued today by the local community and tourists. The project included stabilizing and revegetating the banks of Claymore Creek using a 50:50 ratio of peat and silt, hydroseeding, and layering mulch to create a microclimate over the seeded soil. In addition, three pit lakes were reclaimed by removing debris, backfilling with mine waste, and constructing dams to create a pond to encourage seed germination and plant growth. In addition, one pit was filled using spring-fed streams to create a lake. A later project on the pit included adding a dam to deepen the lake, hydroseeding, and creating two shallow beach areas. https://www.golder.com/download/975/news-support-documents/79103/mining-engineering_august-2019-canmore-creek-article.pdf
