Fanno Creek is one of the Tualatin River’s most significant tributaries. The area in which the two come together is well defined today; but before a north-south railroad line was established here early in the 20th Century, the creek and the river were free to negotiate the location of their confluence across the length and breadth of an area roughly 1/2 square mile in size. Since then the creek has been pinned between an elevated railway bed (to the west) and a steep bluff (to the east). The corridor through which the creek passes just before it reaches the river is less than 300 feet wide. The photo above was taken from a position less than 100 yards upstream from the confluence, which is hidden from view by a large log that has fallen across the channel.
The photo below was taken from center span of Ki-A-kut’s Bridge, the one shown in the first photograph. Note the obvious volume of silt flowing from the creek into the river. The mouth of Fanno Creek lies in the upper-left portion of the shot.
