To safeguard public, crown lands and infrastructure, we have constructed erosion protection structures on the following sites:
This work also includes ongoing attention to each site and involves:
- Infrastructure inspection and reporting (twice annually before and after freshet)
- Vegetation control - keeping area free of trees
- Detailed Inspections to identify any potential breaches
- Repairing damaged sections if required.
New Remo Dyke
The New Remo Dyke and associated protective works are located along the Zymagotitz (Zymacord) River on a registered easement over District Lot 1706 and Unsurveyed Crown Land. The dyke was constructed in 1980 and has a 750 meter compacted earth fill berm. The downstream 400 meter section of the dyke is armoured with riprap (broken rock). Other protective works include a 170 meter section of river bank armouring immediately next to the downstream end of the dyke and a 440 meter section upstream of the dyke.
These protective works help with the continued diversion of the Zymogotitz River away from the community of New Remo. The works are inspected regularly and maintenance is carried out as needed. A copy of the current budget can be viewed here.
Skeena and Lower Kitsumkalum Rivers Channel Management Program
The Regional District of Kitimat-Stikine recently completed a regional flood study of the Skeena and Lower Kitsumkalum Rivers for the purpose of updating regional floodplain mapping and determining options for flood and erosion mitigation measures. The study was completed by McElhanney Consulting Ltd. The study area included the Skeena River from Kitselas Canyon (approximately 15 km east of Terrace) to the confluence of the Zymacord River (approximately 8 km west of Terrace) and the lower reaches of the Kalum River from Deep Creek to the confluence of the Skeena River (approximately 7 km north). Phase 1 of this project was completed in 2008 and included river surveying, geological, hydrological and geomorphologic work. Phase 2 of the project was completed from 2018 to 2021 and included updated LiDAR, updated river survey, hydraulic analysis, updated flood hazard and floodplain mapping, a review of fisheries values for consideration in future flood mitigation, identifying priority areas of risk and developing plans for flood/erosion control.
The outcome of the project included the following documents (found in the document container on the left):
- Fisheries Values Assessment – Report by McElhanney Consulting, Sept. 18, 2020
- Flood Mitigation: Remediation Options of High Priority Areas – Memo by McElhanney Consulting, Sept. 17, 2020
- Flood Mapping and Flood Hazard Mapping for the Skeena River and the Lower Kitsumkalum River near Terrace – Report by McElhanney Consulting, June 15, 2021
- Floodplain Mapping for the Skeena and Kitsumkalum Rivers – Maps by McElhanney Consulting, June 2021
- Flood Hazard Mapping for the Skeena and Kitsumkalum Rivers – Maps by McElhanney Consulting, June 2021
This project was funded by the Federation of Canadian Municipalities (FCM) – Municipalities for Climate Innovation (MCIP) Fund and the Union of British Columbia Municipalities (UBCM) – Community Emergency Preparedness Fund (CEPF). The City of Terrace was a project partner. Kitselas First Nation, Kitsumkalum First Nation, Ministry of Transportation and Infrastructure, Pacific Northern Gas, and BC Hydro were project stakeholders and were consulted throughout the project to identify high priority areas for flood and erosion risk.
