Various barriers to fish migration have been created on the creek and its tributaries since the city was founded. Stage Coach Dam on the upper reaches of the creek was removed in 2002. It had been built in the early 1900s to create a water supply reservoir, but was filled in with sediment. Other barriers have been removed as well, often by creating noches in the middle to concentrate low flows or adding rock weirs to backup the water over an obstacle or provide a more gradual change in elevation.
