Knewstubb Lake Compensation Plan, Vanderhoof, BC

EDI completed a fish habitat compensation plan for an infilled bay on Knewstubb Lake. The plan included linking up an isolated pond to the main lake. Erosion patterns on the pond were analyzed (via historic air photo analysis) to ensure the site selected would be stable. The works were accepted as compensation by DFO and were very successful from a fisheries and cost effectiveness perspective. Rainbow trout have been found in high numbers in the pond since it has been connected to Knewstubb Lake.

Marshall Creek Fish Passage Design and Environmental Monitoring, Haines Junction, YT

EDI was contracted to develop a design for fish passage at the Marshall Creek Alaska Highway crossing, near Haines Junction, Yukon. The design included the use of Newbury riffles to backwater the culverts and installation of baffles to slow velocities in the culverts. Allnorth Engineering assisted with the design works. EDI completed the environmental monitoring works for the construction works which were completed in the summer of 2006.

Interior Watershed Assessment (IWAP) – Tree Farm License (TFL) 30

EDI, in association with P. Beaudry and Associates Ltd., completed IWAPs for Canfor (formerly Northwood) for all of TFL 30. Twenty-seven separate basins were delineated and watershed assessments were completed for each basin. The intent of the project was to develop a cost effective and environmentally appropriate watershed restoration program in the TFL that considered both watershed and landscape issues. The assessments were also used in developing Forest Development Plans that minimize impacts to aquatic resources.

Watershed Drainage Plan, Prince George, BC

In conjunction with Associated Engineering, EDI conducted the Fish and Wildlife Habitat Assessment portion of a Watershed Drainage plan completed for The City of Prince George. The plan was completed for three catchment areas in the neighborhood of College Heights. The Fish and Wildlife Habitat Assessment portion of the study included the investigation of urban stream systems to assess fish habitat quality and quantity, along with the identification of sediment sources, which could potentially affect stream habitats. Adverse affects of land development were identified. Neighborhood green spaces and wooded areas were examined, and their potential for providing wildlife habitat was assessed. A report was prepared, which outlined project findings and provided recommendations for sections of the project area scheduled for development.

Watershed Drainage Plan for Hudson’s Bay Slough, Prince George, BC

EDI was retained by Associated Engineering to participate in the completion of a Watershed Drainage Plan (WDP) for the Hudson’s Bay Slough Catchment Area in the City of Prince George. The objectives of this WDP were to establish strategies and conceptual plans for managing stormwater in order to meet the City of Prince George’s Water Management Policy. EDI's role in the WDP was to address the preservation and improvement of environmental quality and the protection of watercourses from erosion and sedimentation. Fish and wildlife assessments were conducted in the Hudson’s Bay Slough catchment area at an overview level, and field information was collected to determine fish distribution, as well as the quality and quantity of fish and wildlife habitat present. Potentially sensitive habitat areas were identified and recommendations to protect or enhance these areas were provided. Additionally, erosion and sedimentation concerns in the catchment area were noted and recommendations to minimize these issues were provided.

Fisheries Summary, Peel River Watershed, YT

EDI completed a fisheries information summary of the Peel River Watershed. This project involved collecting, analyzing, and summarizing all available and known fisheries information regarding the Peel River watershed in the Yukon Territory to assist with the current regional land use planning process.

Fisheries Summary, Porcupine River Watershed, YT

EDI compiled existing fish and fish habitat information for the entire North Yukon Planning area (Porcupine River watershed). Significant habitats throughout the watershed were mapped and a detailed final report was produced. The end products of this project are being used in the development of land use plan for this area.
