When undertaking the monitoring and assessment of the aquatic systems, it is important to note that effective data collection allows the surveyor to obtain an accurate analysis of the status of the system and how it is being impacted by changes within its environment. If we can determine the causes of these changes, there is a greater likelihood of being able to implement practices to reverse them. This is of critical importance in ensuring the healthy development of the trophic members that shelter and grow in these systems as well as the health of the body of water itself. Conducting a biological survey requires various measurements to assess the diversity of the area, the overall suitability of the system, and whether management practices…show more content… This lake has been surveyed annually for the past 20 years by Vancouver Island University Fish and Aqua Students. Located on Vancouver Island, “Klaklahama Lake is a part of the Nimpkish Watershed which is the largest watershed (2226 km²) on the Island, and drains north into Broughton Strait directly across from Cormorant Island (Alert Bay) (Hyatt et al. 2004).” With such an extensive range, and drainage, it is of critical importance that all contributing tributaries and lakes within this system be properly assessed in order to protect and maintain the species that rely on it. According to a Bathymetric survey of the lake, documented in 1970 by the British Columbia Ministry of the Environment (Harding et al. 1970), Klaklakama Lake has an Elevation of 292.608 m, a Surface Area of 999573.5m², Mean Depth of 7.3152m and a Max Depth of 24.9936m. In addition to these measurements, reports from the British Columbia Ministry of the Environment, have listed various members of the Salmonidae family to be present in the lake such as: Salvelinus malma, Oncorhynchus nerka, Oncorhynchus kisutch, and Oncorhynchus clarkii (British Columbia Ministry of the Environment\FIDQ - Fish Inventories Data Queries
