The rockslide opening ceremony marked the start of the third year of operations adjacent to the rockslide on Fisherman’s trail on June 28, 2018. The objective of the 2018 work was to continue rock break activities to create a continuous channel around the “house” boulder and through the rockslide area, with the aim of reducing the in-river gradient and fill the large interstitial spaces. Contractors began site mobilization works on June 18, 2018 and were able to on 64 days through the Summer period until September 18, when works ended for the season. During that period, approximately 750m of rock was drilled and approximately 760m3 of rock was blasted on nine separate blast days. A relatively uniform channel grade has formed in the downstream section of the debris pile, while a steep 2 to 3m (vertical) section remains at the leading edge section of the debris pile.
This year (2019) represents the 4th year of the project and we’re targeting 6 to 8 weeks of instream works, which will involve less blasting and more manual moving of rock to fine tune the slide area. We are using the same contractors and partners as previous years, with the aim of beginning works in Mid-July depending on Freshet and river levels. The aim is to establish a 9-11% grade through the length of the slide by the end of the Fall rains. We are expecting 2019 to be the final year of drilling and blasting in the river, including the dropping of the leading edge by approximately 2m. Following the Fall rains we are confident of adult migration by the end of 2019.
We would like to take this opportunity also to acknowledge and thank our funding partners and stakeholders, including Metro Vancouver, DFO, the Province, District of North Vancouver, City of North Vancouver, Habitat Conservation Trust Foundation, Freshwater Fisheries Society of BC, Steelhead Society, Coho Society, Supersave Group, along with the Tseil-Waututh and Squamish First Nations.
