Silvicon Services Inc. was retained in 2006 by Pacific Inland Resources (a Division of West Fraser Mills Ltd.) to conduct Routine Effectiveness Evaluations on eleven sites spread throughout the Bulkley TSA. The effectiveness evaluations were low intensity level or routine evaluations. The purpose of the Routine Effectiveness Evaluations was to assess the condition of works at selected sites within the Bulkley TSA that were treated under the Watershed Restoration Program or the Forest Investment Account since 1998, primarily with the intent to improve or maintain fish passage upstream. The sites are all within watersheds that were identified in previous watershed restoration plans as targeted, high priority watershed sub-basins. All sites except the Toboggan Creek site were also identified in Fish Passage Culvert Inspection reports as high priority sites for fish passage improvement. The Toboggan Creek site located on the Silvern Lakes Road was originally identified by the Ministry of Environment, Lands and Parks as a stream crossing that would benefit from stream rehabilitation procedures. Since the sites evaluated were targeted at either improving or maintaining fish passage upstream at road crossings (except for Site 306A which was primarily a deactivation of a decaying structure), most of the physical and biological performance objective fields on the In-stream REE Field Form were not applicable. The sites were assessed for structure function, structure condition, structure stability and maintenance recommendations. As we only evaluated eleven sites and only scored a very limited set of objectives for each structure, summary graphs and statistics were not included in the report, however; fairly extensive comments were included for each site on the In-stream REE Field Form.
