Canadian Forest Products Ltd. (CanFor), Fort St. John Operations, as part of 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 fourth year results of SCQI surveys that were completed in the 2005 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 road-related sediment sources at stream crossings, and the delivery potential of that eroded sediment to be transported into the stream environment. 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 Rating (WQCR), which directly relates to the potential effect that the crossing could have on increasing stream turbidity from the accelerated input of fine sediment. The majority of crossings surveyed in 2005 were on roads built and used for harvesting in the last 2 to 5 years. The most common problems found in all areas were 1) the need for aggressive erosion and sediment control on recently disturbed areas, and 2) the need to disperse water off the road surface and divert it into the forest.
