The river is fed by numerous tributaries and groundwater sources, and regulated by the Rama Road Dam. The flow is influenced by seasonal rainfall patterns, with peak flow occurring during the summer months. The Cedar River is an important source of drinking water and provides habitat for a variety of aquatic species. Interestingly, the river is named after the abundant cedar trees that once lined its banks, but these trees have since been replaced with hardwood forests due to logging and development.
