3.36: Swan River Delta

This large-scale air photo shows detail of the Swan River Delta. Swan River 1 flows northeast into Swan Lake 2 and along with its distributary, Rat Creek 3, has deposited a bird’s foot type of delta. Wooded levees 4 follow the course of Swan River. Back from the levees are marshy areas 5 and lakes 6 with some higher, wooded areas 7. Sediment swirls are clearly seen in the lake 8.
