Evaluation of Restoration Efforts on the 1996 Upper Adams River Sockeye Salmon RunMicroform - 2003
Adams Lake and the Upper Adams River form a potentially major sockeye spawning & rearing area in the south-east portion of the Fraser River basin in the interior plateau of British Columbia. Although spawning salmon were reported as abundant in the lake & its tributaries in the early 20th century, landslides caused by railway construction in the Fraser River Canyon in 1913-14 resulted in virtual elimination of the Upper Adams River stock. This report describes & evaluates the 1996 & 1997 fish culture & nutrient restoration efforts used to enhance & restore the Upper Adams River sockeye population. Evaluation of the releases & nutrient additions was conducted by limnological sampling, acoustic & trawl surveys of the lake-rearing salmon fry, smolt sampling, and examination of freshwater growth patterns on the scales of returning adults. Results from the 1996 brood year are compared with information from other years to examine the effectiveness of the restoration techniques.
