In December of 2009, workers in the Homathko River area noticed an area of substantial erosion near 4.0 mile on the Homathko Mainline and reported it to DFO and the Campbell River Salmon foundation, and finally International Forest Products Ltd. (Interfor). The concern was, that left untreated, would eventually break through into Cumsack Slough, which is a highly productive rearing area for Salmonids.
The site was inspected by DFO on March 4th, and plans developed to protect Cumsack Slough. While on site, effectiveness monitoring on restoration work in 2006 and 2007 was completed.
Snow and wind delayed the project start until March 26, 2010. The project entailed armouring the erosion area with large angular rock and was completed by March 30, 2010.
