 A camp was built on the upper river and logging operations began at Tumtum Lake . The cut logs were run down the river , then towed in booms by the company owned <unk> Helen down Adams Lake . The logs then were run down the Lower river to the mill at Chase . In 1908 , Adams River <unk> constructed a " splash dam " at the outlet of the Lower Adams . This dam allowed operators to raise the water level of Adams Lake . When sufficient logs had been collected above the dam , the gates were opened and the resulting flood carried the logs to Shuswap Lake . This proved to be destructive to the salmon run as it damaged the gravel beds the fish use to spawn .
