The Xausmdas channel was constructed to operate with a combination of groundwater and surface water, which is fed into the channel through an intake on the Machmell River. Sediment from the Machmell River deposited in the Xausmdas channel, filling pools and low gradient runs. Sediment has also blocked the intake, severely restricting flow. These two factors have limited the production of the channel. With relatively low flows due to limited groundwater and a non functioning intake there are insufficient flows to attract salmon into the channel to spawn. These same low flows also limit the amount of rearing habitat in the Xausmdas channel. Western Forest Products and Fisheries & Oceans Canada agreed to conduct a field test to determine if additional groundwater could be delivered to the Xausmdas Channel by lowering Ponds 3 and 4 and by excavating a groundwater interception channel. The lowering of Ponds 3 and 4, plus the excavation of a groundwater interception channel increased flows in the Xausmdas Channel.
