Canadian Forest Products Ltd. (Canfor), Fort St. John Operations, in cooperation with the participants in the Fort St. John Pilot Project (FSJPP), adopted the Stream Crossing Quality Index (SCQI) as their sustainable forest management plan (SFM) indicator for the protection of water quality in the Fort St. John Timber Supply Area. This report presents the fifth year results of SCQI surveys that were completed in the 2006 field season and focuses on both the Canfor operations as well as British Columbia Timber Sales (BCTS) operations within the FSJPP. The SCQI procedure is a field based assessment that evaluates the erosion potential of roadrelated sediment sources at stream crossings and the potential of that sediment to be transported into the stream environment (delivery potential). The numeric score generated by the SCQI is categorized into one of five hazard classes identified as None, Low, Moderate, High or Very High. These five classes are collectively called the Water Quality Concern Ratings (WQCR), which directly relate to the potential for eroding sediment to be transported into the stream and lead to increases in stream turbidity. Various stages of road development were evaluated this year including both active and inactive roads. The most common problems found in all areas were 1) the need for aggressive erosion and sediment control on exposed slopes and 2) the need to disperse water off the actively graded road surface and divert it into the forest.
