A standard fisheries baseline reconnaissance of Upper Manson Lake was carried out by the Fish and Wildlife Branch (Prince George) in August of 1979. The report is on file at the Ministry of Environment, Fish and Wildlife Branch, Prince George.
Upper Manson Lake was investigated in July of 1991 by the Peace Fisheries Compensation Program to identify potential fisheries enhancement
projects.
Two overnight net sets yielded 9 rainbow trout (average length 24 cm, average weight 174.1 grams), 3 lake trout, 1 bull trout, 10 mountain whitefish, 1 lake whitefish, 6 pygmy whitefish, 4 peamouth chub, 6 coarse sucker, and 3 longnose
sucker (indicative of the 1979 netting results). Two minnow traps yielded 1 burbot and 1 redside shiner. Two people angling for 6 hours yielded 11 rainbow
trout, 1 lake trout, 1 bull trout and 2 mountain whitefish. The low densities of rainbow trout captured during the investigation may be related to the limited littoral area in Upper Manson Lake. The lake is divided into two basins by a channel 100
m in length. Moderate spawning and rearing habitat was noted in the channel. Numerous spawning redds were observed in the channel, egg to fry survival is likely. The inlet and outlet are sections of the Manson River. The spawning habitat noted in the Manson River during the investigation, was covered with a layer of organics and/or moss, which will impact egg to fry survival. However, good spawning habitat is assured further downstream. (See report, A Fisheries Evaluation of Lower Manson Lake, on file at B.C. Environment, Prince George, B.C.). Good rearing habitat was noted in the inlet and outlet. A high use (Pers. Comm., J. Ladds, B.C. Forest Service) B.C. Forest Service Recreation Site is located on the east shore of the lake.
No physical enhancements were identified or are necessary at this time. Monitoring of native sportfish stocks should be continued. A fisheries evaluation may be warranted in the future as a kokanee population may result from the Manson River kokanee stocking program initiated in 1990.
