The creek has several tributaries, including Crystal Springs Creek, which flows through a park with several artesian springs. The watershed has several dams, including the Oak Grove Dam, which provides flood control and recreation opportunities. Seasonal trends show that Johnson Creek experiences the highest flows in winter and spring due to rain and snowmelt. In summer, flows decrease and water temperatures increase, which can stress aquatic life. An interesting fact about the hydrology is that the Johnson Creek watershed is home to many species of fish, including coho salmon and steelhead trout, which rely on healthy stream habitats for their survival.
