The flow is largely provided by snowmelt from the surrounding mountains, with peak flow occurring in late spring and early summer. There are no significant dams on Thunder Creek, but there are several minor tributaries that contribute to the flow. The hydrology of the area is heavily influenced by the North Cascades, which receive some of the most intense precipitation in the world. One interesting fact is that Thunder Creek is home to several species of salmon and trout, which use the stream for spawning and rearing.
