Weather today, Tomorrow,

The creek is fed by several small tributaries and is dammed in several locations. The flow is generally highest in the spring due to snowmelt and rainfall, and lowest in the summer months. The creek is also popular for fishing and recreation. A notable feature of the hydrology is the presence of karst topography, which results in sinkholes and underground caves. The creek is also known to occasionally experience flash flooding due to heavy rainfall.
